Does anyone have a diagram of the wires to the 2001 A4 Symphony radio. I want to put in a after market radio, but don't know which wires. Theres four plug to it. It would save me alot of time, testing out every wire and opening the speaker to see the wires.

Thanks

 

cant you just buy a harness?/??

 

buy a wiring harness

 

Yah, I could order one and wait about 10 days but I want it now. I have no radio, lost the code to it.

Well, I got the deck in and the front speakers to work but couldn't find the wires that leads to the rear speakers.
Is the rear speaker power by a stock amp? 2001 Avant Symphony radio. I tested all the wires but couldn't fine the one that leads to it.

Does any one know what wires I have to tap in to to get the rear speakers to work?

 

PM me for the wiring diagram.

 

I don't have the Avant diagram, but on the B5 A4, non Bose, the rear speakers are powered by an amplifier attached to the back of the driver's side speaker.
