Question about Rockford Fosgate Punch 801X Car Audio Amplifier
This can be caused by too low of an impedance from the way the speakers are wired, bad speakers, crossed/shorted speaker wires, and sometimes even a poor charging system (if the amp goes into protect when the volume is turned up) and is usually what the problem is 95% of the time. As you said, very possible to be shorted output devices or shorted power supply rectifiers. Beyond that, it could be a shorted filter cap, some sort of short across the power rails, some sort of short across the output, shorts across the primary. And of course loose hardware - any missing screws or nuts? A loose one under a pc board can short out most anything.
