Whenever I change radio stations, or change between the radio/CD player, my speakers/subs make a LOUD ass poping noise. Anyone have any idea whats up? I have a Sony Xplod CD/Tape HeadUnit with a 10 disc changer in the trunk), Sony Xplod speakers, and Sony Xplod subs. (Dont tell me its b/c Sony is junk. I dont care if you think Sony is junk. They never used to do it, and now they are). Any ideas?
