I just picked up this phone and I absolutely love it, only issue though is the low headphone and Bluetooth Audio Volume. I know I can change the headphone volume by changing the mixer file, but I haven't seen anything on Bluetooth. Unfortunately my car doesn't have an aux port because Honda thinks everyone just uses Bluetooth now -_-. Does anyone know of a way to raise the volume level?
That's strange, because I find Bluetooth to be louder than the headphone output when going to an external speaker. In my car, bluetooth on my phone is maxed and even at 70% volume in my car it's ear blasting loud. You can't use steering wheel controls with the aux cord too.
If you're rooted you can try Viper.
Hello, I have a RK3188 1024x600 head unit.
My subwoofer is hooked up to a digital amp, and the amp is hooked to the head unit subwoofer port (using the Y coaxial converter, and the antena booster "blue wire" as the switch for the amp on/off).
When I play music on stock apps (radio, music, BTmusic, video, aux, ...) the audio sounds great, works perfect, the subwoofer works and the sound is equalized.
But, on all other apps (including Spotify, Power Amp, ...) the sound is tiny, the subwoofer doesn't work and eq is flat.
How can I fix this problem? How can make my subwoofer and eq always active? Or at least turn it on on spotify.
EDIT: the amp turns on along with the head unit, and stays always on until I take off the keys.
Thanks, Gabriel.
did you ever resolve this issue?
I also need to know if this issue was resolved lol
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.
Hello. Im owner of PX5 Android 9 Head Unit for BMW E46. I know hot to change buttons color but i don't know how to make it dimmable. They always have 100% brightness and it is annoying. Should i change something in radio settings or with the cable connection? 17pins BMW E46 sedan 2003 by.
Other question is - are there available mods or DSP settings for best sound quality? In my opinion this HU sound very raw even with enabled Loud. Previously BMW Business CD53 HU had very soft and warm sound quality. I would like to achieve this on this HU too.

The lighting wire (orange) from the radio needs to be connected to the wire in the car's harness that does the dashboard lighting. If your radio gets that signal through a CANbus decoder you will have to cut the wire and connect it directly to the car harness.

thanks i will try that.
And any advices for better sound quality? My previously CD 53 had better sound quality (more soft and warm) than this TDA 7851 based device.
The way you hear sound is personal. Your factory HU would have been tuned and equalized to sound that way so you'll have to play with the equalizer to replicate it. The DSP in those units is missing preset effects like you would find on a home theater receiver. You should probably start by making sure the speaker settings match what's in the car like distance and # of ways. If you find the sound too harsh look at lowering the low pass filter frequency and try a different type of filter. You can adjust the PHAT slider to give the sound more volume. Too bad there isn't an easy way to control reverb directly. Then adjust the equalizer to your taste.

Different radio (original BMW) sound warm and soft. This, even with playing on different EQ settings and DSP cant achieve this warm quality. Im using car amp and hertz DCX 165.3 on rear, Audio system MX165 PLUS on front. Everything is connected to amp via Hi_Lo converter. Should i connect this HU with RCA cable? Does this affect on sound quality?
Also are available somewhere custom setting presets for EQ and DSP?
Oh no wonder you're getting a different sound than the factory radio you're using a line level converter. Some people swear they don't change the sound and some other have better hearing and swear they hear a difference. Either way there's no denying basic electronic principles if you drive a signal through coils it will affect the signal more than just reducing the amplitude. It will definitely add/change harmonics and it might not respond evenly at all frequencies. Something like that is probably acceptable to drive a subwoofer. It would take some finely tuned filtering of the output to get the same signal that went in.
If you're using an external amp you should connect it to the RCA's. The problem with these Chinese HU is the line out level is too low they're still living in the 80's when a 1 V line level was standard. Some amps have an adjustable line in maybe find one that works with 1 V.
It might not matter as much but you replaced the factory speakers, all speakers sound different. Usually aftermarket speakers have better quality and sound than factory.

yes i know, but my external amp and new speakers were installed also on previously radio.
i will try connecting this HU with RCA cable
Hi. I bought an android head unit for my megane 2.2. All the sound is good except that my subwoofer doesnt sound like with my old Alpine player. I recently bought a bigger and better subwoofer, but its still doesnt sound like it should. I tried connecting to audio R and L and it gave a little more loud bangs, but more disortion. I have 1 subwoofer rca cable, bought a Y cable for it to make that double channel but its still the same disappointing result. Can I somehow make that work like it should or cant help that with these android head units. I want to mention that i dont have a subwoofer setting on the unit.

Hi!
If you bought this device in the link then Android DSP equalizer and output chip is to low to transfer bigger wattage to speakers.
One way to fix that is to buy external DSP output with more wattage then default android unit and connect amplifiers to this one, then reroute unit to use this external output.
If you have external subwoofer with amplifier try to decrease output to this amplifier in extra settings or factory menu (pin code) / sound. Output will usually be marked as speakers.
