As the title says I have found a fix for the rear speaker low/no volume problem on the double din android head units that quite a few people including myself have purchased. (Apologies in advance for the long post)
As the title says no extra parts/looms/adaptors are needed, everything i have done is within the unit itself and it is plugged in with the quadlock adaptor provided in the box when I got the unit. Now after the tweeks I have done my volume is the same as it was when i had my Audi symphony unit in.
For reference my car is a 3 door 57 reg s line with no Bose.
1. Go into settings on the unit, the same place you find wifi and Bluetooth etc etc and go to Amplifier/EQ as shown in picture below
2. Next step is to go to fader and adjust it so that it is more biased to the rear of the car as when it comes as default it is set to the centre and will produce no noise from the rear speakers. My setup is below and this sorts the problem of having no volume from the rear speakers but now the problem will be that the volume doesn't go nowhere near as loud as it should do.
3. Now you need to go back into settings as shown in the first picture and click on Factory Settings, this will ask for a pin/password, mine is 126 I don't know if this will be the same for every unit but I found mine in the instructions which for me is an app on the unit as I didn't get any instructions in the box when I got the unit. This will hopefully bring up a screen like below
4. At the top of the screen where it says Audio click on that and this is where you can adjust the volume further and you should get something similar to the next screen
5. At this point you need to increase these figures, the picture above is after I have adjusted mine as I think they were all set to 10 or 12 as default. I first increased the one that says RADIO to 20 and the one that says BT to 20(assuming that BT meant Bluetooth as I play a lot of music through Bluetooth from my phone). This solved the volume problem when using the radio and it was now back to normal and goes as loud as ever but the Bluetooth playback volume was still quite low. After this I went back to this screen and increased them all to 20 which is the maximum and now the Bluetooth playback is just as loud as the radio and now PROBLEM SORTED!!!!!! All volume is now back to normal!!!
I hope this helps someone as when I was looking into buying one of these units I spent a long time trawling this forum and other forums looking for a solution to the rear speaker problems I had heard of and turns out all along for me anyway that it is just a case of changing some settings.
