well

amp stopped working.

it powers on fine, both 15a fuses are fine (switched em both out too make sure).

switched amps, speakers work, so that rules out wireing, headunit, speakers.

tryed running other speakers off the amp, still no output.

not sure what too do...

Wiring impedence too low for your amps?

speakers are 4 ohm, so are my both amps that stopped working.

broken mosfet?

not quite sure what a mosfet is.

Mosfets are in the amps. Something can't be right if both went out.

Mosfets=the things on the heatsinks. google em

no ideas?

not the groud, ampkit, rca jacks.

not the speakers.

not the head unit.

what is ****ing up my amps?

what part of the amp would be ****edup if it powers on without the protection light, but does not put out any sound?

i am so ****ing confused... im not worried about my amps beeing blown, i can live with that, but i dont want too buy a new amp every week.

opend up both amps. Alpine is visually fried, i cant post a pic after work, other one is too (atleast it smells burnt).

maybe just luck of the draw that they both fried on the same day?

I really dont know man :|
