To make a long Story short i got to eat it or fix it.
I have Added a picture. What are the odds of this thing working once i replace the damage, assuming that i can find the parts?
ps: the amp powers on without a problem just the outputs are fried.

Reason: new picture
Measure it with a mutlimeter but I think it's value might be 470ohm. Make sure the transistors are all the same part# before ordering. Most amps use a complimentary pair and the might not all be IRFZ44N's. make sure you replace all the transistors on the output stage an not just the burned up ones.
Good luck.
EDIT: I forgot it's a classD amp, they might all be the same part number.
I found the parts online and from 2 different placed the tottal was bout $22 max for all the parts including shipping lets hope it works i will keap you posted.

I found the 8 burned irfz44n, the new parts # is irfz44npbf . just in case some one got screwed like i did and the surface mount resister are part # CAT10471 from http://www.weisd.com/store2/CAT10471.html

Let me know how it goes i have a JL Audio 300/4 locked in protect mode and it won't come out. Haven't pulled it apart yet but maybe thats whats up...
Crack it open and have a look to see what is burned up. The 300/4 will look a bit different and might use different parts since it is a class a/b design instead of Class D.

What exactly is the problem with the one you have i have a 300/4 that the yellow low ohm ligh stays on. one of the outputs sound really bad and the other 3 sound perfect is this you're case?

I have a switchable 15/30 watt iron, would that work for this aplication? or should i get a better one?
