HELP Power wire touched rca wire at amp port

Aug 8, 2020

Just like the title says, I touched the power wire from battery to the rca wire at the copper plug while it was plugged into the amp now the amp makes a loud humm or whine thru the speakers, I've checked everything from wires to head unit, it affected 2 amps one keeps going into protect while the other works but whines and hums VERY LOUD and it's not no interference between wires. Any tips on how to fix this issue?

You definitely slagged at least one of those amps and possibly your head unit.... that stuff isn't user serviceable.
