Without knowing the impedance of your subs the only indication its right is you did what Duke said. It was kind of a long shot anyway as if they were wired for too low impedance the protective circuits would have been tripping right away not after a few weeks.
I would open it up, look around inside, hope to find something obviously scorched or whatever. Then maybe call some place local. Because as soon as you add in shipping, labor, its really only a $500 amp so where's the value?
Main value I can see is using it as an experiment. Pull some obvious parts, caps or whatever, check values, and if everything that comes out measures good keep it out, put in a bag, you saved what you could, toss the rest.
