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?
