harman kardon

Hi, For my 9-5 estate 3.0 TID 2004 I got a complete AS3 set from a donor car, a 2001 estate. Does anyone know if the wiring from the radio to the amplifier from AS2 is the same as AS3? It would make things a lot easier. Thx Daan

My factory harman kardons reciently started sounding bad, so I wanted to replace my rear deck 6x9s with some 6x9 220w Sony xplod speakers I had lying around, and the had almost no bass and when they did it didn't sound very good, and so I was thinking about getting some 4 ohm rockford fosgate...
