Wait, its only gonna cost me like $5.00 to fix this? Wow! Thats CHEAP! I will put some money in the bank on Friday then order them! Thank you! is there anything else to look at? Do I need to worry about the other transistors? or should I just replace the 4 on the power supply side?

You still need to get the power supply transistor. Future has them.

I checked Futureelectronics and I couldnt find them. Here are some I did find though. Which of these 2 do I want?

Here is the one that is in it now: the MTP50N06V

Here is the IRF3205

Or do i want them both?

The 3205s are a better choice, but you will have to get 20 ohm gate resistors instead of the 100 ohm. Yes that is the place.

Is this going to boost the output of my amp? Cause I have another one that is going to the same sub.

No it is not going to boost the output. It will make the power supply less likely to go out but will not increase theoutput.

Sweet! Thank you so much for your help! I will order everything this Friday. I will verify everything on here before I put it on. Do you know anything about the other amp? Its not that important really.

Ok, I ordered 40, 100 ohm resistors and 10 transistors and 6 MTP50N06V's.
