What's the best android head unit available for <1000$ for VW/Skoda?
Is Quad Core and 2 Gb RAM state of the art?
What if it comes to EQ Settings, MCU sound processor and amplifier chip? I want a good sound and to be able to adjust the sound to the car.

not a fan of "who's the best" but I think this is the most supported android HU
http://forum.xda-developers.com/and...4-4-2-kitkat-head-unit-newsmy-carpad-t2865525
see in the wiki for vw variant, 2bg ram and 4 core. My unit works great, I installed one in golf6 for a friend and mine is going to be installed on my scirocco in a couple of days Have a nice reading
I was curious about what the best was too, but then realized in this scene with these manufacturers the best is essentially the most actively supported. The newsmy carpad nu3001 seems to be the most supported singular model at the moment and the RK3188 variant head unit may be the best spec'd because of the quad core and it appears to be the latest chipset
I would say just look for specs. An RK3188 is the standard right now for what I've seen (don't think there's anything more powerful) and 2GB RAM is more than adequate. Look for other things that you might need/like (screen size and resolution, Android version, etc). In the end, it doesn't matter much which specific headunit you have as long as the chipset is supported so going with a RK3188 means there'll be plenty of options.

Sorry I am not allowed to post links yet. Just google something like "2gb android quad core car" or search for the same in aliexpress.
You'll find 2GB from a few sellers now. Sometimes it's optional.
Which android unit has the best hardware when it comes to sound quality?
THD, Noise etc.
Yup, sound quality and overall quality of the unit matters most to me. I don't need all of the fancy features, but the unit needs to be reliable, well made and playing music in a good quality. I haven't seen that being a priority for majority of the chinese units described here
Have you seen good sound quality in any android unit yet?
Or which don't have good clear sound?

I have a Navall 3 that has a quad core RK3188/2gb mem/16 storage/DAB+FM radio.
And, how is it in general?
How is sound quality?
+1 here for SQ head unit
I'm desperately reading the forum here, and am really keen on ordering the newsmy VW flavor.
I don't mind the software annoyances, can live with them or try to fix.
For me, there are two major hardware concerns:
1. I absolutely cannot give up a superb RCA OUT quality.
Got a Pioneer head-unit now and the sound quality is great!
It is connected to a high-quality amp, a component set and a subwoofer.
If I install the android unit and discover SQ is not as good as my current setup, I will have to ditch it
2. I need the ability to separately control the speakers and the subwoofer.
This should include high-pass/low-pass filters, just like I have with my Pioneer.
I was thinking about using an external USB DAC. Have verified that this is indeed supported with the newsmy units.
But this will only leave me with a stereo out, without the ability to control the subwoofer.
The Ownice units do have 5.1 RCA output, but it looks like they are not well maintained and there are severe bugs plaguing all around their software.
Plus, I love the way newsmy separates the screen from the brains. It would be so much easier to configure and upgrade in the future.
OP - I think we share the same concerns, right?
Now what do we do?

They use quite good parts in that device, the radio is from NPX 6624(Philips), Bluetooth v3.0, U-BLOX GPS/GLONASS receiver, and it has a STMicroelectronics mosfet amplifier (4x 45 watt), but i have a Audison 5.1k system in the car and it sounds fantastic.
You can find all the parts on Google

How often do you use the DVD player? Do you just stream movies directly on the HU itself via hotspotting? I appreciate this thread as I am in the market of getting a new HU. I was looking at a Pioneer but having a OnePlus One that option is out since we do not have a HDMI/MHL output. I know it's a crap shoot with these Chinese radios and do not want to throw money away being a teacher ha

Sound quality is pretty good on these units but they do have limitations regarding the controls for the subwoofer and the HP, LP settings. I also had a Pioneer HU before and this one sounds just as good to me using the same setup (Pioneer components on all 4 doors, 2 Pioneer shallow mount subs and a 1200 watts Rockford amp). What I did was settle for setting LP and HP on the amp and it's been just fine for me. A handy trick I used was that I hooked up the subs to the rear out on the stereo and then I shift the front and rear balance on the HU in order to alter the mix between the subs and the speakers. It's not quite the same as having LP and HP on the unit but it does the trick.

I've only used the DVD player a handful of times (just for testing it and making sure it works actually). I usually play videos from a USB drive or stream them from YouTube, but the DVD player works just fine. It takes a few seconds to start (I find it to be a little longer than it should) but nothing that would be a real issue in my opinion.

Thanks for the great info!
I'm also with a rockford amp (plus a Hertz component, which I'm not sure if sold in the US).
The HU I'm looking at (the newsmy 3001) doesn't even have a way to change balance - just a single pair of RCA outs. I think as a first step I'll try to disconnect the dedicated sub out from my Pioneer HU and use the onboard amp crossovers to HP/LP the components and the sub. Hopefully that will provide a decent configuration. If that works, I will go ahead and get the android unit.
The most critical factor for me was the RCA SQ and your inputs are tremendous here.
Thanks!
War Rasta,
Which unit do you have?

HI
All of the bad sound quality issues I've read about in regards to various Chinese Android head units seem to be related to the internal amplifier/chip from what I can gather.
If you use the pre-outs and run a good quality external amplifier, is the pre-out signal clean enough to sound good, or does it still sound bad, just with more power behind it?
Thanks!

Joying has these new units with some sort of enhanced amplifier and EQ that at least on paper look way better what other Chinese units offer... in fact no other Chinese manufacturer made the effort to offer something better... all go the same route... basic and cheap so kudos for Joying that they are trying something different.
Now we need confirmation from buyers that the new amplif is indeed better....

Yeah, I was looking at picking one of those up, I'm just curious, if I'm not happy with how that sounds, if using a good external amp will actually provide "really good" sound quality vs. the internal amp. I know that using a crappy preamp source can give pretty bad results even on a good amp, but at the same time, the preamp section of these units might be clean enough to provide a good usable signal to an external amp.
Though it would be cool if the new internal amp Joying is using is actually good! Be nice to not have to spend money on an external amp if I can avoid it...

Don't set your set your hopes way too high, after all we are talking about 300-400$ units here. If the sound quality is the top priority these are not the ones to look at, with or without an external amplif. Very good sound quality is expensive. Most (like me) pick these up for the convenience of having an navigation, backup camera, access to various streaming apps and so on... the list is long. My original Ford headunit is head and shoulders above these Chinese units when it comes to sound quality, FM Radio reception/ sound quality.... but it also lacks so many features that you find in a modern headunit that I find them useful enough to give up on the original headunit high sound quality.

lol, yeah, I'm not expecting super high quality sound... I have an older android unit in my truck now, so I know how it feels to have crappy sound.. Just debating if it's worth spending the money on an external amp to help things out... Not sure if it'd be worth the expense/trouble to install, or if it would just make crappy muddy sound louder.
Love the convenience of these units though, especially compared to my 20 year old stock CD player, talk about a huge technology update!
Suppose I'll just get one of these new Joying units with the new digital amp and hope for the best...
Thanks again for the info!
I have one and should have it running in the next week. It's my understanding that if you enable an external amp with the new units the surround sound is disabled and the old app is enabled. In other words you lose all the fancy adjustments if you use an external amp. I have a few cars and one of them will use an external amp and I'm only just hoping for less heat from the new design. On another car I'm hoping to bypass the original amp with the new unit and drive it right from the joying unit.
Of course sound is pretty subjective so I'm doubtful even if I say its better that that is meaningful to anyone else in their car etc. A the end of the day I like decent sound, but the android functionality is my primary need. One of my cars is a Honda Element. This thing has so much road noise a person might be throwing their money away if they went with premium quality.
400 bucks can either be a lot for someone or less significant for others.
well now the Sony Android Auto unit is down to $400. I was actually never unhappy with the sound of my Joying, but holy **** the sound is dramatically improved with the Sony:
https://forum.xda-developers.com/an...-xav-ax100-t3647891/post73238321#post73238321
However, I do miss the full functionality of Android, so I'll be going back to either Joying or Seicane. But after having that Sony, i may look into adding an amp or a DSP or something to try to get that sound
i got the new Joying with the Amp and DSP, and I think it sounds pretty great.

The old Joying is ok as long as you install Viper.
Do not compare onder units with Joying Intel based units...
I have all amplified on my car, with Joying 2Gb Intel unit (not the new ones with digital amplifier), but applyied some on stock audio cars and sound is not worst than pioneer, kenwood, sony 100-200€ units.
But to made the sound better, disable LOUD and on Car Settings app, on the code protected menu, on balance sound option, put the sound bars on 0 (zero). Now you can volume up without distortion and the sound will be more clear.

No, the problem isn't with the amplifiers. The amplifiers they install may be somewhat small, but they're not bad units. The problem is in what they send TO the amplifiers, which will be exactly the same if you use an external amplifier.
All that an amplifier actually does, is makes the sound LOUDER. If the sound that you are amplifying is full of noise, artifacts, and clipping, then those *painful* bits of sound will also be amplified.
I know this thread is a blast from the past, but in searching xda i am having a hard time finding if any of these android headunit make clean sound out the RCA.
I have a Sofia unit from about 2 years ago, and have never been able to get rid of whine of the engine across rpm range (especially if engine is running with headlights on) i have a good grounding kit under the hood, quality 4 gauge power and ground to amp, tested PAC SNI-1 Noise Isolators on both front and rear RCA, have even tried a Axxess AX-ANR1000 Power Noise Filter. All to no avail.
Is there any units that are better for clean output?

Filtering noise out of a system like that can be a bit of a daunting challenge.
There are a ton of different places where the noise can be brought into your radio from your car;
1) ANY electrical connection between your car and your radio. This includes power+, power-, and even all the different *signal* wires, like ACC, headlights, reverse, etc.
2) RF. This is a really challenging one to deal with, because if your alternator is blasting out a whole bunch of RF noise at a frequency in the range of 20-40,000 Hz, and if that RF gets picked up by an audio wire pre-amplifier, then the amplifier will take that noise, amplify it, and play it on your speakers.
You've tried a power noise filter.
Have you tried connecting the ACC line to the filtered side of that filter instead of the ignition? Have you tried disconnecting ALL of the other signal lines coming into the radio?
Now about the RF part.
Here is the thing. If you're using the pre-amp audio outputs, then that means that you are bringing the pre-amp audio signal OUTSIDE of the protection of the metal box (faraday cage).
The SNI-1 ground loop isolator that you've tried isn't going to do a damned thing if your problem is RF noise. In fact, it is an idiotic part altogether since all it actually does is it converts a signal from one ground reference to a possibly different ground reference. Instead of that, what you should be doing is making sure that there is no potential difference in the ground reference level of the two parts being connected -- specifically, the radio, and the amplifier.
Two things you can do to help with this;
1) Add a big cable from the amplifier chassis to the radio's metal box.
2) Use the highest quality and SHORTEST audio cables possible.
Also... have you confirmed that the amplifier you are using isn't actually the source of the noise?

Thank!
I can confirm it's not the amp itself by a headphone to rca cable from my phone into amp w/o noise.
1.) I need to try running a wire from amp ground to cage of hu. Think better to attach to ground of the case or attach to powerline filter? Going to test with bridge both wires of premium speaker wire. That should be plenty right?
2.) only wires that are a bit longer than needed are the rca. Might be 2ft slack because amp is under passenger seat.

Hi,
I looking for double din with android with sound quality,
I'm not an audiophile but looking for some quality, I know that chiense android double din
comes with crap quality.
So my question is if you know some android double with quality ? or maybe to add DSP to get some ?
Thank you.
Having excellent audio quality is probably not a priority for the chinese. If you want audio quality you're better off buying a brand name radio with android auto.

You can add a USB DAC output. There are a few out there with full 4 channel control. But simpler stereo ones are nice too. The caveat being your amp need to have built in crossovers and your sub will have to be remotely controlled for level.

With the android auto, what I will see on the screen? it will make mirror ?
Off: is there any point having Android Auto on a HU with Android?
Android Auto for sure would be great on a proprietary HU system with closed OS widening its functionality. Android HU functionality is already Play-market-wide. At least very close to "infinity" . I may be wrong though.

Perhaps somebody would be kind enough to clarify what is wrong with the audio quality of these units, at least with said quality for the ones equipped with DSP (which as far as I know is nowadays the norm for MTC* units). According to my personal experience (and of course taste) these units sound great, and certainly better than OEM.
In case it matters, I had three such units in two vehicles:
(a) 2011 KIA Sorento with non-premium, non-amplified sound system. I started with an old (2015-ish?), wheezy RK3066 MTCB unit with DSP (though a limited set of controls was exposed to the user) and it produced excellent sound. I then tried a more recent non-MTC*, non-DSP unit and even that produced decent (though not outstanding) sound -- certainly better than OEM but not by much.
(b) 2013 Mazda CX-9 Grand Touring with premium (Bose), amplified sound system. A MTCD PX5 unit (with DSP and the same limited set of controls exposed to the user) feeds its preamp outputs into the factory amp of this vehicle. The resulting sound quality is excellent.
In all, my question is why do people complain about the sound quality? It may be argued that the sound quality is not audiophile-level, but I will argue back that such quality is useless in a noisy automotive environment. There is also a long thread of back-and-forth arguments regarding a dedicated DSP versus the on-chip one, but again from my experience I side with the people who claim that the on-board DSP is good enough for this application. In other words, I believe that the limiting factor is not the audio system, but the noisy environment of a vehicle.
Myself I am able to actually hear most nuances in classical music (between other genres, I mention this only because it is the most challenging for an audio system) in my car over road noise, which in my book makes for an outstanding sound quality for the application. So what's the fuss?
So which unit do you recommend then? I've been looking at the pumpkin 8.0 unit. But haven't seen many reviews, seen a lot of talk about joying but there is so many different units and I don't really know what I'm looking at, I just want the latest and greatest I guess?
So i was browsing through joyings new intel head units on their site with DSP. I found that all intel based joying headunits with their DSP now have a SPDIF coaxial output. This is a huge step for them since many of us been trying to use a USB DAC for toslink or SPDIF output.
A regular name brand HIGh res deck with SPDIF output runs over 1200$ . And their not even touch screen.
Joying finally woke up and did it, now us guys with fancy name brand DSP’s can finally send true digital coax output to them. I will be ordering one of theses units and not utilizing the dsp that is built in. Simply because i find that they are not there yet with their built in dsp’s for individual speaker functions. I have a nice audio control dsp that has a coax input.
Enjoy!
if u order it pls make some pics of android board and som
Subscribed... I'm thinking buying one. I found two version. 2/16 and 4/32 GB. What do you suggest? Enough the 2/16, or better the 4/32 version?
Depending on what your looking at doing with the unit. Im going all out with the 4gb of ram. I caught myself multitasking on the 2gb ram units (not joying) and the audio would studder sometimes.
Theses new joyings will change the revolution of car audio with this coaxial output!
Ill be able to listen to “tidal” app do get high lossless sound tracks right to my Audiocontrol 608 DSP via coaxial.
The only other way to do digital sound is an ipad or the highly priced sony unit at 1500$ for a single dine with no display?.

I will try and do so
Just ordered mine, but with 2.5inch curved IPS display. I will try to make a frame to fit my car.
I won't be using the digital out for now, I will try the RCA out first and see. I like the build in eq.
My last joying unit had hissing noise when not playing music, hope this one will be quieter.
Yeah. For the average user, their dsp seems to have eq front and rear independently. Which is nice.
You can also order a longer ribbon for their screens to locate the unit in a different area from their screens. This would probably help with the mold you want to make for your display.
If you have a high fidelity sound stage like me. : tweeter on an amp, mid ranges on a separate amp, woofers on another amp . Then rear stage on another amp, then all amps hooked up to a 10 ch output dsp to control each speaker independently.
The built in dsp is no good for me. But the digital output will be king to supply my external dsp with digital audio??

I did research some DSP (Thanks for the tip on youtube). I came up with the Rockford Fosgate DSR1 for $283, which was the cheapest of them all. I will wait and try out the build in DSP first before jumping onto this one.
I currently have an 5 channel infinity amp coupled with a pioneer monoamp for the sub.
I am also using component in front and coaxial in rear. I am using the crossover that came with infinity speakers for the front.
Not sure if I should connect the sub directly to the unit or leave it connected to the infinity amp. I will have to play around and see which gives better sound.
The rockford is a nice unit, i tried it out myself. I am not sure if it has a coaxial digital input. I forget.
Another thing i did not like was it does not have presets and their app is not too android friendly...(to be run on a head unit apk)
And i also forget if it has volume control knob...
This is why i went with audio control.
My head unit should be arriving by next weekend i hope . Then ill be gearing up to make a huge review video , based on audio quality and features and obviously the new spdif digital output!
Can you test the rcas as well and not just spdif? I'm planning on getting one myself but I will only go digital if the normal rca output is bad. Also can you test spdif to see if you can control the volume through headunit or steering wheel controls instead of using dsp volume knob? I guess if you could be as thorough with some of thr main feature(wifi, Bluetooth, 4g, sound quality from both outputs, camera input etc) that would be very helpful. I've never pulled the trigger on an android headunit because the lack of some features and poor sound quality but I'm almost ready to get this one. Which size did you buy?
I will for sure be doing exactly as you mentionnned above. I will also be using my oscilloscope to measure distortion in the rca’s. I had a eonon headunit and there was terrible noise in the rca’s and even more noise when a Hard drive was plugged into the usb ports. And more noise with my 360view camera hooked up.
I will be doing bench testing first then i will be moving to vehicle testing.
I bought the double din 10.1” headunit intel with 4gb ram and 32gb ssd.
Its going in my 1997 chev c/k1500 pick up. I have hifi audio in there . Ill be doing more upgrades down the road as well.
Sweet. I'm excited to see the results. I just hope it isn't a let down. I really want to go ahead and order one but if you're doing a review I'd rather wait. I've wanted an android head unit since they came out. I've even looked at building a raspberry pi or like rock pi and adding a screen but I just don't think I'd be happy with the results. These Android head units really have a lot of features but the sound quality has been the deal breaker for me. I asked JOYING what their rca voltage is and they always tell me they don't have voltage... Not sure what they mean but whatever. For all of our sakes I hope this one gets the job done.
Mine will be delivered tomorrow, but I wont be to test it out until next weekend since i will be out of town.
For sound, i will be using the rca going to my amp, not planning g on using a DAC right now.
Just make sure you tell us about it as soon as possible lol.
Just got mine yesterday, but what a disappointment, no digital audio out. Although I did order the one with the digital audio out.
I emailed them back, but they told me they are on vacation and will not return until Feb14 or something, but the lady said she will replaced it for me.
I just powered it on on my bench, so I have not been able to play with the audio in the car or the equalizer, will do so this weekend.
The 10.1 2.5D curved screen is nice though

Dang that sucks. It looks like it has the 4g dongle built in. Are you able to test that out?
Usually its under the yellow cap... instead of the yellow video 2 out, it will be a green rca. Take off your yellow caps.
My video should be on YouTube by tomorrow.
Everything you can ever possibly want in an android headunit is finally here. Crisp sound through the digital source and no noise or hiss on the rca’s .
Be patient i will post a youtube link shortly. Better grab popcorn, my vid is 1.5 hour long lol

That's great news. Can't wait to see the review. Did you order model(JY-UO134N4G)? I want to make sure I get the right one when I go to order.
I've actually purchased a few of these over the years, mostly because they were very vague on this specific feature. Given many of these units are identical just rebranded copies it's hard to sort things out.
The following is based on countless hours searching the web and 4 or 5 personal purchases of these Android head units. If any of this is incorrect please tell me because I have been desperately searching for one due to BMWs incessant need to one off everything.
In my experience the bottom line is no. Android head units do not offer genuine sub support. Yes you can use the rear output and a line converter or run the signal into the high level inputs on your amp (if it has it) but there is still a very simple a basic problem. You still won't have the needed components and or firmware to properly run it. Specifically frequency control, crossover or even a 7 band eq on the unit. I only found one that offered that last and it was janky to say the least (more probably offer the eq now but still very subpar) assuming you can run v4a on the unit that may clear some up but that was written for head phones not a 4 or more speaker system.
Another point is most mainstream headunits, pioneer, Kenwood, alpine heck even boss have 4v rca preout and signal conditioners not to mention both high and low-pass crossovers.
Unfortunately to my knowledge these Chinese Android suppliers have really missed the ball. Yes they offer some cool features but car audio guy's spend many thousands of dollars on these systems and to be honest I have a avh-4500NEX in my 325xi and since it mirrors wirelessly as well as Android auto and car play wireless it provides excellent sound.
Major difference my NEX $1800.00 us brand new these Android's I've seen get spendy but mostly right around 150-400. But you get what you pay for.
The biggest bonus I found though was you can put them anywhere since they are mostly just and inch or two deep.
If I missed the mark please let me know and if you could send a link to where I can pick up a decent one. The I-Drive in my 535i is making a stereo upgrade next to impossible
this is the honest **** i been scouring for... as a AV guy everyone keeps telling me go daisaita blah blah blah but everyone here seems to not have ears or know what they are talking about when it comes to sound... my original gut was to pick up a NEX but i got side tracked with Atoto and the rest because everyone talks out their ass about how amazing they are... with no clue about their soul purpose

They have amazing abilities for instance the iDrive in my 525i is old and outdated and these Android HU are the only option and they are fully functional and compatible which no mainstream HU can claim that I'm aware of. But I'll deal with old and crappy and tap the harness for a signal for my amp before I'll downgrade on sound quality.
You can use an Android successfully IF you install an EQ and probably noise filter but there goes the saving you would have seen.
Spdif out to dsp-amp is possible with Joying for example. SQ shouldn't be problem with it.

I've had pioneer, Kenwood, Alpine, Blaupunkt and a few others and you haven't missed the mark at all. The audio quality on these Chinese head units is just not comparable and the RCA output voltages (1.4 volts) are standards from 15 or 20 years ago. And yes... they are NOT true sub outputs.
Now having said that, it doesn't mean that you can't bring the audio quality up to par. It does however require some extra money and extra components. I don't run Dasaita's sub outputs but rather have an active electronic crossover which can generate a sub output and I run that plus the Dasaita's front/rear outputs through an AXXESS dsp sound processor before the signals go into the amps.
It's certainly a bit of extra money spent on top of it all, but IMO, worth it because these Android head units beat out the traditional Kenwood's and pioneer's in just about every other respect.
It WOULD be nice however if these Chinese manufacturers started paying a bit more attention to audio quality at the end of the day.

Apparently you haven't played with any of the recent Joyings....You also obviously don't have much experience with different cell phones out there either.
Ok, fine....show me a Pioneer, Alpine, Kenwood, etc that can run Google Maps, Waze, Firefox, Gaia Navigation, Torque Pro, APRS Droid, etc natively, right on the unit....just ONE unit, from ANY of the "big name" manufacturers...they just plain don't exist. Not a single one that runs Android natively, or anything else other than their own, completely closed souce, proprietary OSes that we can't do anything with beyond what comes installed on them from the factory. Don't like their nav app, launcher, or general interface? Tough schmitt...
I've said the same thing for many years...I'd be HAPPY to drop a $1,000USD or more on a solid unit from a major manufacturer that runs Android natively. Or even a Linux based OS, that I can add additional apps to. Hell, I was dropping a thousand plus on putting a touch screen in my dash connected to a PC tower in the back YEARS before these factory double din units hit the market. Some company like Pioneer drops one of them, and I'd be one of the first in line screaming "take my money!!".
Screen mirroring isn't an option for everyone either, as screen mirroring is largely based on Miracast. Especially so for anyone with a Google phone, such as my Pixel. Google has gone out of their way to limit or even eliminate that ability to push more sales of their lousy Chromecast devices, and they have stripped Miracast support out of the core Android as of version 6 (Marshmallow). If your phone supports screen mirroring, that's because whoever made it added Miracast support back in themselves. Android Auto is also a rather lousy compromise for many of us, such as myself, that want to run alternative apps. If it wasn't coded to run within Android Auto, it generally ain't happening which is the case for the navigation app that I use for off road purposes.
I've tried several different Pioneer double din touch screens with several different Android phones. Never once was I able to get screen mirroring/mirrorlink to work correctly to truly screen mirror the phone. Only the crippled Android Auto worked...which is what ultimately pushed me into completely going with these Chinese Android head units.
That said, the Joying JY-UO135N4GS - https://www.joyingauto.com/joying-l...avigation-system-with-built-in-4g-module.html that I have in the truck right now does have a 16 band EQ built in, F&R RCAs as well as a dedicated Sub RCA output, though it's a single. I haven't put a meter on it to verify voltage, but I'm guessing it's around 2V based on gain settings on the amp compared to other head units that I've known to have 2V outputs. A LOT of "brand name" head units today still come with 2V outputs. Also has both LPF and Subsonic filters on the sub output, as well as independent HPF crossovers on F&R channels. I currently have my subs set to 30Hz-100hz, fronts set to 80Hz high pass, and rears at 135Hz high pass (yeah..blame Chevy and their piss poor design on their trucks). Subs are a pair of JBL GTO 12s fed by a Kenwood monoblock amp. Door speakers are Infinity Kappa 6.5s, rears are factory 4x10s.
Is the sound quality on par with the Pioneer head unit that it replaced? No. Can I hear the difference at 75mph over the wind and diesel engine noise? Nope. Maybe I'd hear the difference if I put one of these Joyings in my Cadillac...Do I plan to replace this Joying with a Pioneer/Alpine/Kenwood/etc? Wait for it....has not ever once crossed my mind. I also have a Joying in my Suzuki Samurai, and am shopping for another Android unit for my Suzuki Grand Vitara.

If you are fine with sub par audio Then your opinion doesn't matter
The #1 purpose above all the bull**** you rambled on about is SOUND that's the purpose of an aftermarket head unit... Regardless of additional features

It's already been stated that audio quality is not the best. It's also been made clear that for some extra bucks and a few more components you CAN have your cake and eat it too. Now if you wish not to go that far then why are you here? Go to the pioneer forums.
As for the purpose of an aftermarket head unit.... yesteryear it WAS all about sound. Now it's more about central information centers. All kinds of information at your fingertips... and these Chinese units just beat the crap out of ANY of the traditional units as general information centers. Try hard as you can to make a traditional head unit do something to this level of detail and customization:

Now.. do I have to put some extra money in making the sound better? Yup, sure do, but to my eyes it's worth it.
I´m running my Joying still from speaker out to Match M5DSP. SQ is even now better than with stock HU (PSA MyWay) that I used to feed M5DSP. I don´t hear any problems and I´ve been hifi-guy nearly 30 years.
Why is it not a true subwoofer output? I have a 1500w rms amp connected to the green subwoofer output and a dayon max mx12 and its clear as day. My only problem is my hengcheng which is like a teyes c3 clone only has front rca output and I want to leave my front speakers on the tda7851 built in amplifier and connect my rear speakers to a 200w amp in the back. But if I use the front rca out I will loose fader control cuz the system will think my rears are front speakers. What about the output voltage? I don't have a line out converter and everything sounds fine.

They are mostly the same but not all the same, I.e. MTCD with MCU mod sub out.
Yes, line level is 1.5-2v RMS not 4v as car audio mostly is.
Your post doesn't list "Android units" so cant tell what your test units were.

Which one is
Excuse my ignorance, I don't do high end stereo builds for cars(home theater yes).
Just curious, if you're trying to put out that kind of wattage and care that much about crystal sound, why aren't you using spdif(optical or coax) to output digital from your stereo regardless of brand. Then your Head unit is for the features/apps and screen and your high end equip is for signal processing?
Because the optical is 5.1 so a DAC would be mono output to each speaker, and there isn't a digital rca spdif or optical that is stereo. I thought about doing that and just using y cables but not with it really the signal wouldn't be any better just less chance of interference and I have none. An amp with optical starts around 1k unless you go aliexpress or something. My amp topsolidgear 1600w 1 ohm stable as tested by wiliston audio on YouTube is $150. My Dayton MX12-22 12" subwoofer was $140. I have it running 600w @ 4 ohm and its already crazy. After I break it in I may switch to 1 ohm and get even louder. My speakers are coaxial ds18 3 way black diamonds ($39) and my rear speakers are component ds18 6.5 with 3.5" bullet tweeters with built in crossover ($70) so it's a budget system. But it sounds great. All my audio is high resolution lossless flac files and the dsp does a great job. The 32 band equalizer let's me adjust subwoofer frequency and speaker frequency so I can turn my speakers off between 30_whatever hertz and set my sub anywhere from 30_70 hz range. It also has time delay and surround function and turns my amp on and off with a trigger wire amongst some other settings I haven't figured out yet.
Can't figure out what bass enhancement does. Bass filter is to filter bass from speakers and surround is to adjust timing.
Here is a pic.

My speakers are coaxial ds18 3 way black diamonds ($39) and my rear speakers are component ds18 6.5 with 3.5" bullet tweeters with built in crossover ($70) so it's a budget system. But it sounds great. All my audio is high resolution lossless flac files and the dsp does a great job. The 32 band equalizer let's me adjust subwoofer frequency and speaker frequency so I can turn my speakers off between 30_whatever hertz and set my sub anywhere from 30_70 hz range. It also has time delay and surround function and turns my amp on and off with a trigger wire amongst some other settings I haven't figured out yet.

"there isn't a digital rca spdif or optical that is stereo"
not sure I understand this statement? Digital is stream is whatever is on it the stream. I send stereo over optical all the time in home theater(well I used too, it's OLD now ;-) Yes technically each speaker would be mono(it's channel) maybe I'm missing something.
I understand your point on cost, but if you already have the amp you want with solid RCA then just use a 50 dollar 4.1 or 5.1 DAC to RCA
It will skip the "crappy" DAC in the the HU and avoid interference(sorry but from what I read they ALL have it). I know both mine do.
The only reason I can think it will still be bad is if they are still doing DAC then reversing it for the optical. Again I have not tested the optical on the one I have with it as my stock system doesn't do spdif or even RCA.
