If I'm not mistaken, Rockford has the same tech support people as Rockford. Try contacting Rockford for the schematic diagram.

Is the gate resistor within tolerance for that FET?

Do you have a bad solder connection or a broken trace on the gate leg of that FET?

Are these new FETs? If so, if you swap it for one in another location, does the heating follow the FET or does any FET in that location heat up?

Post the resistance between the first and second legs for each of the transistors in that half of the power supply (8 total).

Measured the feet of the image in black and red.
I written values ​​in the image.
Transistors are IRF3205.
I measured directly on board.

The ones that read significantly less than 100 ohms are defective. All of them need to be replaced.
