hi everyone. working on a kicker cxa300.1, mp18021 replaced, irf3205 on ps and irf640 in the outputs, only for test, the amps works fine. now which is a good substitute for aot460 and aot412? i cant find on mouser and i dont use ebay cheap mosfet for outputs.
this is a 300rms little amp, im thinking the irf3205 works ok, more id and only 5v less on vds. but i dont 100% sure.
the aot412 are 60a and 100v, i have irfb4110 used on another bigger cxa at the ps, can i use it like output? these are 130a 100v more than twice the original part.
thankss

I expected someone with more definitive information would have replied by now.
Can you post a photo of the output driver IC and drivers (if it uses drivers)?

it use irs20957. maybe irfb4227 is a good option? i know some 800rms amps use 4 of this in half bridge with 2092 like the pioneer 8601. a pair cant handle easy the 300 rms of this kicker.
The 4227 would be a much better option than the 4110, especially if the driver IC has no buffer/driver transistors between it and the FETs.
The IRF3710Z may also be an option for an FET of 100v.

The over-current protection is related to the RDSon of the FETs. The OC programming resistors may need to be adjusted when using a different output FET.
