I think you have to change protection diodes,Sometimes they seem to be ok when not load but when the power gets in they change the behavier or it can be the regulator ic which is fualty.........
I hope your problem is gonna be solved

In most of Rockford's amps, the low voltage detection is connected to the remote input. If the remote voltage is too low and they use the same circuit on this amp, it could trigger the protection circuit.
Disconnect the head unit's remote from the amp. Use a fuse holder with a 3 amp fuse to jump between the B+ connection and the remote terminal of the amp. If the amp powers up, the head unit's remote output may be defective. If it blows the fuse, the remote input or part of the power supply is damaged. Do not try it with an unfused jumper.
