I think I may answer my own question, but when I've found after I installed my amp and sound system that when I raise and lower my wake plate I get a pop from the speakers when I trim the plate. I'm thinking this might be a grounding issue from the amp???? Or...could it be coming from the where I wired in the on/off wire which is in on of the non used aux switches next to the throttle. Oh...it's a 2006 21V
Any suggestions?
Thanks!
