Hello
I have some trouble with this amplifier (rockford fosgate punch 120.2).
First the two mosfet(Q7 and Q6) for the power supplies was out and the mosfet for one channel was out died too (Q219 and Q215).
After changing them by irf9640 for the irf9540 and irf 640 for the irf 540 the amplifier power up good but i have some noise with the amplifier output that i change the mosfet.
I have 1.20v to the output.
Did someone have the schematic please?

Contact Rockford to see if they'll email it to you.
Have both the exact model number and the PC number from the board.
The 640s may be OK for testing but likely won't be as reliable as the 540s.

Ok thanks a lot for your advice Perry.
I have send an email to Rockford but no answer for the moment.
Wait and see
I will take some mesure to compare with the other channel

The attached diagram may have a similar circuit but none of the circuit board designations will match.
