I am parting out my stereo and lettin some very powerful amplifiers go for cheap...

I have 2 Alpine MRV-1507s and 1 (for now) Alpine MRV-T757 to choose from. All are in great shape and never had any problems. The 757 has some minor scratches on the case but nothing major. Asking price for the big amps (1507) is $375 each obo plus shipping. Asking price for smaller amp (T757) is $250 obo plus shipping. The 1507 will power 3 12s/4 10s easily
and will really throw down on somethign like 2 12s or 3 10s. The 757 will power a couple of 10s no problem. I used them to overpower my front components.

DO NOT LET THE AMPERAGE RATINGS FOOL YOU...these amps are highly underrated for sound competition judging purposes. 1 Alpine watt=5 MTX watts...seriosuly.

Damn! I wish I had the money for T757.

Do you think that amp would be a good size to power some Boston Acoustic Pro front components? And can it also power the 4X6 plate rear speakers?

I had this amp on a pair of boston pro 6.5 components before the tahoe in my grand cherokee and i won every sound compeition i went to. They got louder than $hit and sounded clean as hell. Nothing better than puttin a ton of power on a pair of quality speakers. They will power the 4x6 plates too but i wouldnt recomment it for 2 reasons. It is only a 2 channel amp so you wont have your front/rear fade. More importantly i hate rear speakers in trucks. My friend has a lifted z extended cab with a t757 on boston pro fronts and no rears and he gets trophys everytime we go to competition. The fronts will be louder if left powered by themselves and the sound staging/imaging of it will be 100x better.

I'll back BogeyBoy82 on the quality of Alpine amps. I have a 4 channel, MRV-407, so its running around 60 watts per channel. I have a set of 10" Fosgate He2's hooked up on two channels (thats the way it had to be done with 4 ohms and dual voice coils), and it bumps like no other!! Good amp, damn good price.
