Question about Rockford Fosgate Punch 500a2 Car Audio Amplifier
Have you checked on the fuse terminals?
Maybe the zener diode along B+ and ground got shorted when supply was reversed.
Check for for the continuity along the supply line. Also, consider if there was a sudden surge of supply that busted parts along the filter line of your unit.
