I am looking to add a aftermarket amp and sub. I however would like to keep the stock HK head unit and everything in tacked. I order a RCA addition kit that taps into the speaker wires, in the wiring harness on the back of the head unit. Anybody know which wires were the speaker wires or how to find them? I am in the air about taking it to the professional. I skimmed through the forum a little and didnt see anything.
