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.
