Alpine MRP-F250 4-channel Amplifier
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 versatile MRP-F250 4-channel amplifier can take on a variety of roles in your system. Drive your front and rear speakers in 4-channel mode, or switch to 2-channel mode to power a couple of small subs. Want the best of both worlds? Use channels 1 and 2 to power full-range speakers, and bridge channels 3 and 4 to power a sub. Any way you use it, this amp will impress you with its strong sonic performance.
Variable high-pass/low-pass filters let you adjust the frequency output for either full-range speakers or a sub. If you're driving a subwoofer and using the low-pass crossover, a subsonic filter eliminates inaudible, ultra-low bass notes for cleaner output.
The amp's rugged construction ensures reliable performance. A heavy machined-metal heatsink keeps the internal parts cool and distortion low. Gold-plated screw terminals resist corrosion that can degrade signal performance.

Pros: clean sounding amp!
inexpensive for 4 channels
Cons: the only problem i've had is when my jeep has been running hard, the amp loses power because (i'm only guessing!) my alternator needs to power it up again, turns on after about 10 minutes.
Comments: Like I said, great amp! Alpine really did well with this one. I used to have an iffinity reference amp. and the A/B to these is amazing! Alpine blew it out of the water!

Comments: This is a great little amp. It powers my speakers and gives me a good crossover to shape the sound.
It is very small, very thin and doesn't ever get hot. It's made with Alpine quality. It also has a blue light on the top that lights up when it is on and that is a neat effect. Sound quality is excellent and there is no noise coming from this unit. It also hasn't ever shut down on me, even when blasting the stereo for quite a bit of time.
For the price, and the Alpine quality, it's very hard to beat.
