My amp smoked, easily fixable? (pics)

[XanderMoser 10+ year member]

I finally got some free time to remove and take apart the Orion HS2.125 that smoked when I hooked it up and turned the car on. It looks like it's a few resistors and maybe the MOSFETs, but I don't know anything about this stuff really. I can solder and have friends who are really good at it, and my dad knows where to get any parts and has fixed amps before. So if it is fixable, it shouldn't be a problem.

For those of you who have seen many amps fry, would any of you know why this happened? I am 100% positive I had all of the corrections correct. It was bridged to a 4 ohm load when I turned it on, the gain was all the way down, and it was all the way down on my crossover, so it wasn't even getting a signal. Maybe there was something in there that shorted it?

Any help would be greatly appreciated. I want more than 160 watts on my sub //content.invisioncic.com/y282845/emoticons/frown.gif.a3531fa0534503350665a1e957861287.gif

If any more pics are needed, I can get them.

chances are that there is more than just a few mosfets gone... probably some caps and other crap... but all is replaceable except for tha board. if you got a bad trace in tha board then u might as well throw it away.

I would say just go ahead and replace the mosfets and the correct resistors and see what happens. The only worse thing that can happen is that your out a few bucks.

If you replace one MOSFET, plan to replace them all.

Thanks everyone. The guy who sold it to me is really eager to help me, even offered to pay for parts. So at least I'm not out $90.

Yeah, I saw that on an amp repair site. Good advice, thanks. All of my damage in on the PS part of the amp, so is it okay if I just replace all of the PS mosfets and leave the speaker mosfets (or whatever you call them, the non-power supply ones)
