hey i have a spare mrv-t757 sitting around. How much you lookin to spend. I bought it a year ago from a guy who came into an audio place i worked at for a short time for 300 bucks. He brought it in claiming something was wrong with it, so i sold him a big ol rockford amp. turns out hes an idiot and had it wired wrong, too many ohms. he had his subs wired for like 16 ohms (2 dvc subs in series at 8 ohms a piece). The amp sounds great. i love it. I think the 757's were highly underrated, cuz itll out punch some of the much bigger amps ive seen. I think its cuz of the kick *** parametric equalizer. I tell ya, i could play with that all day and never get tired. anyways, i never got around to using the amp much. I set it up and it took too much space in my trunk with my 2 12's and my other 757. I think the 757 and 1507 were the best amps alpine made. They are solid and built like a tank and never shut down on me.
