Android Head Unit-use Bluetooth as source to Amp - Android Head-Units

I'm looking at an Infinity Kappa K5 amp and it says it has direct bluetooth connection capability, so I got to thinking. It seems that there is a consensus that the audio quality of all of the Android head units is poor. Does anyone know if you can setup the head unit to be the bluetooth source to the amp? Can anyone test this theory by using a bluetooth boombox? I'm really interested in an Android head unit but the poor audio is not an option. I know Bluetooth is terrible too, sometimes, but this was just an interesting thought.

Low Quality Bluetooth Audio (Treble distorting)

Hey! I'm more of an Android newbie (I have an iPhone). I just installed an Android head unit in my car. So far everything is pretty good except the Bluetooth audio quality. Whenever a cymbal hits in a song, it distorts and sounds really bad. It doesn't distort when playing music any other way. I know it's not my iPhone, because it streams to other devices just fine. This seems to be a common problem in some radios, and even just the android OS. How can I fix it?
My radio is an Android 6.0.1 unit with an Octa Core chip, 2gb of ram, and 32gb of flash, which I bought from Idoing on AliExpress (since it won't let me post a link)
Thanks!
I'm having the same issue. I'm really bummed about it as I love the unit but the bluetooth sound quality just sours it
I've read people just getting Bluetooth dongles and attaching them to AUX, but that's more of a hack then a solution.
We may be SOL if it's a hardware issue. I'll keep searching.
After reading a lot of the MTCD threads I've heard people using this Bt+Wifi dongle

According to reports, the head unit will use it as the system's internal Bluetooth.
I've ordered one and once it arrives will report back on it this fixes our issue.
Dont know if it's relevant, but I'm using the preamp outs on my unit as my car has a builtin bose amplifier,
@bonesteel94 are you using the preamp outs or just the standard amplified signal from the head unit?

Android Head Unit + Pioneer DEH-PRS80

Hello everybody , I'm owner of Ownice C200 Chinese head unit and i hate about audio quality and Bluetooth. I was using Behringer UCA 202 Usb dac but few months ago it stopped to work. Dac working with other devices but with head unit it is not working. When i use USB audio player, I can hear sound via headphone but from stock car speaker , no sound. For this i bought line converter to connect directly RCA from USB dac, but then i learned it need amplifier to power speakers. ( if i am wrong , please correct me)
I search a lot of topics in XDA and i saw one message using two head unit in car but there is no more information. I want absolutely same things. I want to use Pioneer deh-prs80 ( i will hide it somewhere in car) and will continue to use Android head unit for navigation, watching movies, rear view camera purpose. Is it really possibly ? I don't want to install any amplifier to my car, i don't need loud music, i just need clear and crystal music. I have hertz esk 165.5l as speaker.
If it's possible how will be connection ? Car battery enough to make power for both head unit ? ( i will connect speaker wire to directly pioneer) , is it possible to connect android head unit to pioneer via aux or Bluetooth or what ? I wish when i use android head unit, sound will go to pioneer and this head unit amplifier to speaker quality sound.
I also wonder if it is possible can be sound quality difference playing directly from pioneer or through android head unit to pioneer ?
I hope this topic will help to people who suffer from audio quality expect other features in android head unit..
Nobody can help ?
Well I would connect it via Y Splitter and the Front RCA out on the HU would go to the AUX in the Pioneer deck and connect your bluetooth to the Pioneer HU instead of the Android. You would have to zero out the sound from the Android and adjust your EQ settings from the Pioneer to get the best quality needed.

Hizpo Android Stereo, no audio for bluetooth cell calls

Maybe someone can give me a hand with my head unit. I have a Hizpo Andriod 7.1 for my Porsche Cayenne. The install was easy and works great but I cannot get a bluetooth cell call to work with an iPhone 6 plus or a Samsung A5. Both phones connect no problem and you can make a call on the screen but there is no audio out of the speakers and the person at the other end cannot hear me. I can listen to music by bluetooth so I do know it's connected. I even bought Apply carplay and it makes no difference. Any ideas? Maybe there's a setting I'm missing?
Same here, Hizpo PX5 Android 8.0 .
I can start a call from the stereo, but the phone will still use its internal speaker for the audio.
Did you resolve in any way?

Play car sound on bluetooth speaker

So I replaced my head unit with a after market one a few months ago.
the exact model is an Xtrons TE706PL.
I also have a good set of car speakers ( 2x pioneer ts-g1720f (front door), 2x caliber cds46(trunk)
they work great and stuff but when I try going for more bass the sounds starts cracking. I know I could get a subwoofer to fix
but I wanted to try if it was possible to connect a bluetooth speaker to my car headunit. I have a JBL Boombox which sure pumps out more bass for sure. My idea was maybe trying to connect the JBL boombox to my headunit via bluetooth and using it as a Sub.
Did anyone try this? Is it even possible? if not I think I might have to get a Sub after all but I'd rather keep the 200-300 dollars in my pocket (I don't have a separate car amp and even though my head unit does have a sub input I'm not sure if that's actually a good think with the head unit amp(4x 45w)
any other thoughts and Ideas are more than welcome.
PS. im not 100% sure if this is the correct place to ask this

Head unit with fully working bluetooth?

Does anyone have an recommendations on an double din android based head unit that has a fully working bluetooth module? Something that can pair with and control an Alpine PXE-0850S amplifier. Does such a head unit exist?
Thanks
I would also like to know if such a product exist.
With new headunits including plenty of memory, storage, fast a75 cores and 4g -but high noise floor and only 2 slow usb ports+crippled BT is such as letdown :-(
I noticed the Atoto units have two bluetooth modules and support bluetooth tethering. Any chance those will pair with generic devices?
Well, I answered my own question by buying an Atoto S8 and trying it out. The second bluetooth module seems to be a normal fully working module and does pair with the Alpine amp and allows the amp settings to be configured using the Alpine app. However, since the amp also supports bluetooth streaming, whenever the head unit connects to the amp over bluetooth it routes audio output from music apps (but not the radio) via the bluetooth connection (instead of spdif), bypassing the head unit volume controls. So whenever I want to change the amp configuration I have to pair it with the head unit, run the Alpine app, make the changes, and then unpair the amp. Grrrr.....
