Rockford fosgate punch 240x4 mosfets?

chipper · 11th February 2010, 02:34 AM

I recieved a Rockford punch 240x4 amp for free from a relative but he said it didn't work so I took it home and opened it up and it didn't have any power supply transistor fets. Everything else looks okay gate resistors but not sure about the driver transistors? What are the original part numbers for the fets or what's a good sub? IRFZ44? Or something else? Thanks

The IRFZ44 would be OK. The originals were MTP50N06V.

Power the amp up and measure the DC voltage on the gate pads for all of the power supply FETs. What do you read on those pads?

Place the black meter probe on the amplifier's ground terminal. Place the red meter probe on the point where you need to measure the voltage.
