Hi guys. This is my first thread so bear w/ me. I own an 01 X5, no nav, non DSP, no premium sound. I'm putting the finishing touches on my first mod, installing my changer in the center console and building and installing a sub in the right rear where the factory sub would go. I've read virtually every post on this site about the subject and other sites as well. I'm still trying to locate the infamous "blue Conn" for the sub signal. The only one I've found so far is on the left rear near the amp. It has 15 wires going in and is terminated w/ a 10 pin black plug labled AMP. Is this where I get the factory sub signal?
I'd like to thank the guys who run this site and all of you who posted. It has been a great help.
