I am replacing the head unit in my truck. I have a JL Audio A4300 amp that has been rock solid with the previous head unit. When I turn on the truck and power up the amp and I get a whine from the left speaker. I don't have to start the truck for this to happen. If I swap the L-R speakers, obviously it goes to the right speaker. I do not have the RCA plugs from the head unit connected to the Amp.
Left channel Amp issue? Any ideas if fixable?
