I have a 325Ci with no power to the rear speakers. Does anyone have any suggestions for tracking down the problem?
I have the same problem in my `02 525, every once it a while I hear a loud pop and the passenger side speaker works but just barely. I have checked connections at the head unit and the amplifier except I can't get one of the plugs out of the amp. The AM reception gets crappy at times too. I assume that might be caused by the antenna amplifiers that are in the C pillars but I am not sure. I troll the Bimmerfest forums looking for answers but haven't found any. Chris
