I have a -97 A4. I recently bought a new kenwood player for it. The old player didnt have rear speakers connected to it. Also those wires who keep the player memory saved when car is not on werent connected (cant remember the english word for it). When i installed the new player out everything was otherwise okay but those wires i mentioned were all ripped off from the adapter, so my rear speakers arent working at the moment. The problem is i dont know which wires belongs to what device. I've googl'd a lot but havent found the answer, as my audio wires seems to be completely different coloured from others. Wires are blue/green, blue/red, white, white/yelow and 2x brown/red. I think the brown/red wires are minus wires for rear speakers but im not sure. Im asking for your help to recognize the wires for me.
E: I think the car had blaupunkt player stock.
