Hi all,
can anyone tell me the correct psu & output mosfets for this amp. I believe it has the same board design as the Hifonics z500d. It has the hip4080 chip.

There has to be more to the output marking.
In the Hifonics amps, I use the IRF3205 in the PS with 47 ohm gate resistors.
The only thing I've found that worked reliably for the outputs in 4080 amps is the IRF3710Z (Z is critical). I've never tried the transistor that's installed. It may be better. I don't know.
