panasonic cq-c5301u tech support manual
all speaker channels and the rca preouts have static coming out speakers. Even when speakers are hooked up through an amp they sound bad. There are no grounds and raido was professionally installed. I've tried changing speakers and installing ground loop isolator. Still poor sound quality. Any ideas or maybe tech/ support guide?
