rockford fosgate power 1001 bd
Hi I need help with ROCKFORD FOSGATE power 1001. when I hook it up it squeals and draws massive amps and the out puts get warm. I unsoldered the twisted red and black and powered the amp back up and it powers up like its supposed to and the twisted red and black have 110 v.

Sounds like you have some shorted outputs.

Do you have a multimeter?

all outputs test good.

Is there any DC on the output terminals with red and black twisted wires hooked up?

You can power through a current limiter.

How did you confirm the outputs were good?

Does it immediately draw excessive current when remote voltage is applied or does it take a few seconds before the excessive current draw begins?

Do you have a scope?

Yes it starts out with 90v then goes down to 45v on output terminals. and I tested them with my DMM.
It doesn't immediately draw excessive current it takes a few seconds. No I don't have a scope.

If you lift one side of R31, will the amp power up fine? This disconnects the preamp section from the power amp section.

Just want to see where the problem is since you do not have a scope.

Hi Sean yes the amp powers up fine with R31 lifted.

Post the voltage on all the pins of U17.
