ive had a kicker kx600.1 amp installed for over a year with no issues . as of 3weeks ago i broke the rca cable and didnt have another but did have a line converter so i installed that ,no issues there either. now this morning for some reason the protection light is on ,amp doesnt work, and every so often it tries to get power but goes right back to protection. i put an old 600 bazooka in and that seems to run fine. any ideas whats up with my kicker?
