[QUOTE="HardofWhoring, post: 8851341, member: 674149"] If you just swap RCA's at the amp, you can figure out if its the head units channel or RCAs, or if it's the amp and the amps ground. There's no reason you can't take the amp out, wire it short to the battery, and as close to chassis ground, as you can get if you can find a good obvious ground. Something I have found before: Your head unit's wiring might not work for the cradle/head unit space. I have found with a vehicle before that once a head unit was mounted, the bracket behind the head unit was putting pressure on the RCA cable plug behind the new head unit. That was causing resistance and a ground loop. Take the head unit out of the mount, and sit it somewhere so that none of the wires have pressure on them. If you haven't isolated it yet, that RCA cable might be making contact with a bracket or something else behind the head unit that's giving it a slight bend and resistance. We actually had to switch to a different head unit because of what side the RCA plugs were on. [/QUOTE]
