Cant figure it out!!! Audi 2012 S4

[Dave Rensberger]

Its been almost 1 year and still cant get this fixed. Ive tried so much trouble shooting. Looks like only the Chinese after market head units are compatible with my car. Ive tried two different head units and the same issue happens. My vehicle was the last year before bluetooth audio so it has to have an AMI Plug plugged in the glove box to get a AUX signal. What ends up happening both head units which was easy to install is driver side speaker all do great volume and the passenger side is very low volume where I need to put the balance a good amount to the right, also there is a high pitch noise in a few speakers as well. My unit has the factory amplifier and wasnt sure if the amp maybe and the new head unit is giving two much power. Or is this a ground issue? Ive checked the connections many times and again on now my second unit. The head unit works great and if the sound could be equal and more balanced It would be perfect.

Ive installed these units before on other audis but this one again has the AMI MULTIMEDIA system.

Help please

It may be time to bypass the OEM amplifier. You can still use the original speaker wiring to prevent running new one. Since you are using an aftermarket radio, you will wire direct to the amp via RCAs.

How would you bypass the factory amp? What steps would I need to take and do? Sorry I would consider myself a non-expert and the advance audio stuff. Is this something I would be doing with the new head unit? Any help would be appreciated.

If you have a technical mind you can do it yourself. Depending if you have a Bose or B&O system, you Google 2012 Audi S4 amplifier pin out. Compare the harness to your's. You will snip the wires going out of the amplifier to the speakers and splice them towards the new amplifier. This is the most difficult part.

Metra or somebody may make plug n' play harnesses so you can avoid hacking up the OEM wiring.
