Dead amp?

So, I had just picked up a Rockford Fosgate P300-2. A 2-channel amp. I had purchased it for 20$ knowing it wasn't working. But I was hoping it was just a blown fuse. Either way I have a good (In my perspective) amplifier. So, I crack it open, and I find that the right-hand side MOSFETs are blown (HUF75344G3) Those ones. Since I have no knowledge repairing boards. Could anyone let me know what had to of happened for this tow happen, how to fix it, and if the amp is toast?

Short on the output, abusing the amp.

Somebody had it at too high of an output and overheated it.
If only MOSFET damage is all that is fried anybody with common sense could fix it in an afternoon. Only buy exact replacement MOSFETS and discharge capacitors& pcb board before opening amp. Use a good solder wick tool for desolder. Also buy quality tub of rosin Flux .
