Nah. I'd rather fix this one and learn how to repair amps. Plus I'll mod it while I'm there for 1800 watts @ 1 ohm for around $50.

check the rca inputs on the amp. the outer part of the connector(the ground of the rca input) breaks loose from the rest of the assembly and can cause similiar issues to what you are having. MTX is notorious for rca input issues even going back to the old thunder series amps. My brother in law had the baby brother of your amp, an mtx thunder 801D . This exact thing happened to his amp. A little time and some solder and the rca ground was solid once again and the amp worked perfectly. if the rca inputs seem loose this could be your issue or it may just be part of it. the broken rcas could lead to other failures as well.

No way I'm spending that much on it.

quality repairs cost money period. sure maybe the parts themselves that are replaced are not that expensive but there are a lot of little odds and ends that are a necessity for any real amp repair tech. Insulators,heatsink compound,solder, desoldering braid, soldering iron tips,chemicals, etc all add up quick . not to mention the labor and education involved for this sort of thing. a good tech is doing a lot more than just soldering some components onto your amps circuit board.

I agree but I'm hoping I can fix this amp. I mean there is only one thing holding me back, right?

if you are gonna attempt the repair yourself if it even needs repair I suggest posting the amps model number and symptoms in a thread at http://www.diyaudio.com/forums/car-audio/ . there are several very good amp repair techs there that can walk you through most repairs if you are willing to take the time and listen and invest in some decent tools for doing this kind of work.

Thanks so much guys for the help. I truely appreciate it! Well he forgot to bring the amp with him this morning so no pics or anything today. Only new info he told me was that he ran it hard for about an hour and then it started doing what I described earlier. Thanks a ton! I'll keep everyone up to date. Hopefully he'll bring the amp tomorrow (he's a coworker).

If your going to try and repair it yourself, I'd highly recommend you buy this.
