I have a Md3d thats broken, could possibly need a new board (i know nothing about amplifier repair though).. I was told should be around 150 for repairs with someone assuming the normal issues these would have.. You could have it for free if you want to pay for the repairs
Edit: Oops, 2 ohm, hmm.. I dont know if you could make it put out its power at 2 ohms, but i put it out there if you know anyone that does good work. I would suggest DBDesigns, but he must be having problems right now or something, so its probably bad timing.. I've never had an amplifier repaired out of warranty, if i had a problem with my sundown amplifier i'd turn to him or where Jacob goes which would be DB-R. If your interested though, i could probably find out whats wrong with it.
