Audi A4 B8 2012 Concert (Non Bose) Bypass OEM Amplifier - Need Radio/Amp Wiring Info

[dawoodessop]

Hey Guys,

Been searching for ages on the net and these forums but cannot find the answer to my question. Hoping you gurus can help out.

Scenario and Goal:
- I want to remove the OEM Amplifier on my Audi A4 B8 2012 with Concert Radio (Non Bose and Non MMI). I will be replacing the Amp with a DSP and Amplifier.
- I DO know that I can use the High Level Outputs from the OEM Amp however I want a cleaner signal into the DSP and less equipment in the car. There are plenty of write ups about the high level output wiring and colors - I don't need this.

Challenges 1: I want to know what the NON High Level wires are in the OEM Amp harness. The twisted pair wires are as follows:

Orange / Violet -- Orange / Brown : Can Bus (Purpose: Switch on amp, Other ?)
Green / Black -- White / Black : Audio ?? (??)
Green / Blue -- White / Blue : Audio ?? (??)
Green / Yellow -- White / Yellow : Audio?? (??)
Red / Violet -- Brown / Violet : Audio ?? (??)

Challenges 2 : What will not work if I remove the amp from the system.?
FYI - If I have unplugged the harness from the OEM Amp and the radio turns on and seems to function normally
Does the CAN BUS Serve any other purpose for the amp?

Challenge 3:
Best place to get Remote Turn on for DSP?

Thanking you in advance!!

By a PAC audio adapter for that model it will solve all your problems and yes the can bus controls speed - climate - and oil display. Disconnecting will throw errors.

If you have Bluetooth audio module currently that will cease to work because the output into speakers will be bypassing amp now.

I put in an alpine style unit in mine way better solution if money isn't a big deal. About $1,400
alpine x701d only sold in Europe. Buy on eBay.
