I finally got my Kicker ZXM 700.5 5 channel amp and my new 10" POLK MM1040 Sub installed. I also installed a dual batter system with just the dual battery switch. System is working really well and I love the extra warmth that the sub brings. The only issue I have is a CLICK that feeds through the speakers when I move the wake plate. I have the stereo and amp as well as the + & - busses hooked up to the stereo battery and just the engine hooked up to the other battery. Any suggestions? mabe move the -ve bus to the starter battery?
