Outstanding audio performance — you expect it when the amp is an Alpine. Alpine's V-Power amplifiers supply the high level of performance you want without shaking loose too much of your hard-earned cash.
The MRP-M450 mono subwoofer amplifier will power your subwoofer with 220 watts of power. Add a second sub and the MRP-M450 pumps out 400 watts of power — enough to get almost any car shaking. The variable low-pass filter adjusts the frequency output to match your system, while the Bass EQ lets you dial in some extra boost on the lows. A subsonic filter eliminates inaudible, ultra-low bass notes for cleaner output.
The amp's machined-metal heatsink keeps the internal parts cool and distortion low even when you're cranking the volume. Gold-plated screw terminals and RCA connections resist corrosion that can degrade signal performance.

Comments: I have this amp powering my 12" Alpine sub and I have not experienced any problems with it at all. I especially like how it is small enough to fit underneath my driver seat in both my wrangler and my cherokee (before I got rid of it)
Comments: This is, like the MRP-F250, a very small, VERY powerful amp. It's very thin, and pumps out 400 watts of power (not peak power) to my dual 8" JL subs. Sound quality is great, and the amp has never shut down or even gotten hot. It also has a very small footprint and is very thin.
This amp also has a blue light on the top that is a neat effect that turns on when the system is turned on.
Overall, for the power, and the Alpine quality, this amp is hard to beat.
