Have a Rockford fosgate power tm750x1bd amp. Not shore what happen befor I got it. Had a few output transistors and fets blown already. Replaced all the blown fets. Checked all gate resistors, they're still good and within tolerance. But when i attempt to power up the amplifier, only one particular fet in the power supply section keeps blowing. Happens only when I apply power to the remote. Blowns with in secs. Q4 is it location on the board

I do have a short in between the negative of the power input and negative subwoofer output terminals
A shorted transformer would likely short from the B+ to the secondary ground. What you see is likely normal for an amp with balanced inputs, assuming that the amp doesn't have a full bridge output.
What is the PS driver IC part number?

See if you can get the diagram from Rockford if you can't get to the IC (or at least identify it by pin configuration.
Does this amp work like the older amps and produce drive signals with only ground and remote?
