Default MTX TA8502

I purchased this amp new and ran it for close to 3 years without problem on a single 9500 wired at two ohms. I sold this sub and replaced it with a pioneer w3004 spl, long story short the sub must have been wired at a unstable impedence for the amp to handle or out of phase. This caused the amp to go up in smoke, with my warranty expired I decided to investigate and found that the speaker input terminal fried out at the board. I have a decent amount of electrical knowledge, but resistors, transistors, fets etc are like speaking jibberish to me. I have a fluke mm, and a nice soldering setup, but am lost on choosing replacement parts. I have no clue on what, where or how to locate these parts and any knowledge you would be willing to share i'd be more then happy to soak up!!
