I've been serching forums for a while now trying to find two things: the location of the factory amp and a wiring diagram for the amp of an 06 or 07 X3. I have found a lot of stuff on the X5 but info on the X3 is much harder to come by. Any help or a point in the right direction would be helpful thanks. (P.S. ive tried using the online WDS but none of the pictures are comming up and i just updated my adobe software so i know its not that)
