Hi, I have 2004 X5 car, with business radio\cd, and I would like to add the BMW Sub to my car, I saw that it has 2 speakers, so its - 4 wire.. But the connector has 12 wires... can anyone please explain to me - 1. Why does it have so much wires, 2. The wiring diagram of the sub, so I will be able to use my non-BMW amp to connect it to the sub.
thanks ALOT in advance,
