I've searched and read a bunch of threads here about how the 900W HK is anything but "premium." I agree it sucks pretty bad. I'm thinking of installing in the trunk a small Pioneer mono sub amp and small subwoofer I have laying around that I was going to use on another vehicle. I would tap into the high level signal wires coming from the amp mounted in the left side of the trunk to feed the sub amp. I don't want to lose volume or balance/fader control of the head unit.

Has anyone decoded the wiring colors/diagram for that factory amp?

I assume the factory amp has a built-in crossover to split high, medium and low frequencies which are then fed to the factory speakers?

Thanks in advance!
