The IRFIZ48 has been a good sub. There are a lot of other fully encapsulated FETs but these have been used a lot of times.

According to pacparts and kenwoodparts, they're discontinued.

And wondering if all the diodes are the same according to the schematic .
Since there are multiple diodes with the same board locations
And the diodes I took out have all different part numbers and they are shorted

I think that will work. This is the rectifier for the driver voltage for the output transistor drivers. I don't know how much current they need to handle. I initially looked at 1 amp diodes but saw the 4 amp of the same size so I picked that one.
I also thought about the BYV-28-150s that were used in the old Rockford amps. The BYV-27 would also likely work. Many people who work on vintage Rockfords have those in stock.
