Was the heatsink grounded to the body of the vehicle?

Are you sure that you don't have a bad speaker or bad wiring?

Are the center legs of the outputs shorted to the heatsink as well?

The center legs of those 5 fets are directly shorted to the ground terminal and the ground terminal this 1 ohm from the heatsink

Were all of the screws in the board (holding the board to the bottom cover)?

It's strange that the outputs are shorted to ground but I guess that's possible if the rail switching outputs are shorted.

Even if I disconnect the 3 jumper wires Between the 2 boards the short is still there.

It appears as though one of my mesha strips for the power supply fets is bad. I get about 6m ohms from the back to the front pads.
Would anyone happen to know where I could find some mesha strips.

Can someone send me schematics for a Rockford T40001BD amp to matt76.brooks at gmail dot com

I have replaced the output FETS b/c 10 out of 20 were blown. The powersupply drivers checked out ok. But, i am only getting -110V for -HV output and ~9v for the +HV side. any thoughts.

You might be better starting a new thread and detailing the tests and checks so far performed.
