Friend had a total sound system installed. Now his CB Barley Receives. At First subs hit great now they come and go. Last week he lost sound to one speaker think we have it traced to one channel bad in amp. I need some help i feel it is mainly due to the power side. The guy ran a power feed up from batteries. Not sure yett how i still need to look at it. I am thinking that it may be a grounding issue. I keep hearing talk about isolateing the grounds. Can someone give me some ideas i can look at next time he gets in town.
