Default TOTAL DESTRUCTION OR HAPPY FET

If a 12 volt amp with two 25A fuses and 4 IRF1324 FETS is connected
to a battery with the polarity reversed would the fuses protect the FETS?
If the fusses are replaced and the battery polarity is corrected will the
amp still work with a normal life span?

I have not done this, but I may have an amp that has been wired backwards.

You could do a quick check of the mosfets and see if they are shorted D-S.

Could be you got away with it, or you havent and you have destroyed one or more parts of the circuit.

If the mosfets test ok fire it up and see what happens.
