I am in need of a little direction here...

This amp has the 12 IRF064N's in power section and 10 IRF9640's and 10 IRF640N's in banks of 5 each side with the DWM1216 (2610) Audio driving board.

I have the amp powered on and plays audio but i believe the load its driving to the subwoofer is not up to par what it should be. Im averaging 30V A/C on the output terminals with a 2ohm load before clipping. It just seems like its really weak. I dont have anything for comparison. I have scope and am good at following directions and have the repair tutorial but I am just stumped.
 
At D32 FMG33R and at D33 FMG33S.

Voltage going into the amplifier is 12.89V

Under heavy load the voltage is drop for my power supply is about 1 volt.

I have attached what I am seeing.

Rail voltage +-73 No Load and +- 65 under load.
