Bumping this old thread, hoping for some resopnses. I have a 2002 M3 coupe, HK system that I am about to upgrade. I want to replace all the factory speakers, but use the factory wiring and upgrade the HK amp, hoping to get some feedback on this thread before I cut any wires.

anyone have a good link to the wiring diagram of the HK amp?

Thanks!
