My buddy's Hifonics Zeus 3000.1 is having problems.
It works fine until we had to move it around and it got a little shook up. It'll power on and everything fine except when RCAs are plugged into the "Input" side it goes into protect. It did this in his car with the RCAs coming from a LOC, straight from his head unit, and in mine connected straight to my head unit. It's not the RCA wires themselves because we've tried 3 different pairs and as soon as I hooked my amp back up with the exact same wires it works fine.
Does anyone have any idea how I could fix this?
