Rockford Fosgate P250.2 - No Power

I have found a Rockford Fosgate P250.2 2 Ch. Amplifier (250W) that is being sold for next to nothing but it is being sold as-is since it does not power on.
Here are my questions:
1. Is there a typical cause to this type of problem with this product?
2. Would it likely be fairly inexpensive to perform the repair?
3. Could a working version of this product power 2x 12" 4 ohm subs and sound pretty good? Or would 1 x 12" 4 ohm sub sound better?

Any information is appreciated.
Thanks

    If there is no power and the fuse isn't blown, it's likely that the power supply FETs are blown. The parts are likely to cost less than $15 if that's all that's wrong with it. They are soldered to the MEHSA insulator and you'll need a small butane torch to remove and replace them. You should also be able to buy the insulator/transistors assembly from Rockford but I don't know what it will cost from them.



    Sometimes, there are other problems that cause the power supply FETs to fail. If the output transistors failed, they could have caused the FETs to fail.



    With either of these faults, there may be additional damage which may or may not be difficult to troubleshoot.



    It's also possible that the board is badly damaged (sometimes happens when the power supply FETs fail). This can make it difficult/impractical to repair.



    If you buy it and need help with it, let me know if you need help repairing it.

1. no all amps can go bad with a bad installer !
2. repairs sometimes go for as much as it was new! so somettimes not worth it!
3.1 12 4ohm would sound lot better i reccomed mono amps for subs being they only put out low feqz and are better and more battery effient!

I need a schematic for a RF p300-1 amp. Im trying to replace 2 of the mosfet semiconductors that got fried.


There are no schematics for RF amps, normally RF uses standard IRF Mosfets. Can you decribe the area where they blew, Power Supply are usually N-Channel high current type. Outputs can be either N-Ch or P-Ch depending on the Power rail there attached to.
