Will do .
The power supply fets are burnt outputs are defective .
Do you happen to know what might have caused all of the power supply filter caps to vent ? All 12 of them vented

High ripple current (possibly from a failing power supply, not an instant failure) or possibly a reversed battery connection.
Last question . What’s the best way to clean the board to get the electrolytic off the board since it’s everywhere .
For the board, I prefer acetone. Bear in mind that if it's in the vias, it will eventually eat through them so do your best to clean them as well.
Do not use acetone on any plastic like the top cover. Alcohol is generally safe for plastice.

I replaced all of the power supply filter caps , power supply fets, drivers for the power supply and all of the outputs .
As soon as I add the remote wire the amp draws excessive current.
Any ideas on what to check ?

Ok o tracked the problem to the power supply driverboard .
Does anyone have a high res pic of the power supply driverboard ?

Ok went back through he amp and replaced the power supply drivers again .
Amp still draws excessive current .
Is there a way to look at the drive signals without pulling the whole amp back apart ? And damaging the fets

Why would you have to pull the amp apart?
Connect only remote and ground (no B+) and the amp will produce drive signals. This works on a LOT of the Rockford amps.

Do you read continuity (approximately 0 ohms) between the collectors of the Q100/103 on the main board?
I'd say that the NPN driver is bad if that's what you have on the base and you have 12v on its collector.
