It's possible that the installer cheated on wiring gauge, using wire too light for the 12v side causing the voltage to be dropped to a level the Fosgate won't tolerate and causing it to shut down.
If you have a multimeter, monitor the supply voltage at the amplifier while a friend turns the volume up. If you see a significant decrease in the 12 volts, the wire feeding the amp is too light.

Quick question, amp problem


make sure you ground wires arent shared, meaning run each ground wire from each amp to its own grounding point
