You blew up the DC-DC converter in the power supply. The whole PS is going to have to be rebuilt not to mention I am sure some output transistors are bad as well which caused the failure. I would say you are looking at $200 min charge. Those amps are nice and very well built.

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.
