Our take on the Alpine MRP-M2000

by Buck Pomerantz

My system has plenty of power. Who needs an amp?

You might think you don't need an amp because you have a 400-watt system in your car, or because your new stereo puts out 50 watts a channel. But those are peak wattage ratings, which may boil down to 15 or 20 watts per channel, using the more realistic RMS rating. An amp sends your speakers the power they need to deliver your music with clarity and impact, whether you're using factory speakers or high-performance components. And low-frequency reproduction requires lots of power, so an amp is an absolute must if you're adding a sub to your system.

Alpine Authorized Online Dealer

V-Power amplifiers deliver the sound quality that made Alpine famous. Highly efficient power supplies housed in sleek black casings guarantee that these amps stand out in performance and appearance. The thermal management system dissipates heat and saves power, so your V-Power amp will run reliably for years to come.

The Alpine MRP-M2000 mono amplifier drives your subwoofer system with up to 2,000 watts RMS — this workhorse will satisfy the hungriest bass setup. The low-pass filter puts you in command of the frequencies that reach your subs, while the variable bass boost is armed with plenty of low-end punch. A subsonic filter prevents wasted energy by eliminating ultra-low bass, putting all the power where you need it.

Preamp- and speaker-level inputs allow you to connect this amp in almost any vehicle. Let this V-Power amplifier transform the sound of your car's audio system.

Inputs: The amplifier offers both RCA line-level and speaker-level inputs for 2 channels. The supplied speaker-level input harness allows you to connect this amplifier to a receiver without preamp outputs; aftermarket or factory. The speaker level inputs will accept the output from a high powered radio.

Terminal Covers: The amp comes with two plastic covers that protect and insulate the RCA, power, and speaker connections. Four supplied screws attach the covers to the amplifier.


Low Pass Filter: The amp has a low-pass filter, continuously variable from 50-200 Hz with a slope of 24dB/octave. This being a mono subwoofer amp, the crossover is always engaged.

Subsonic Filter: This amp utilizes a subsonic filter to eliminate super low frequencies that can rob power and damage speakers. The subsonic filter settings are 15 Hz, 30 Hz, and off.

Bass EQ: The Bass EQ circuit provides a variable boost (0-12dB) with an adjustable center frequency (30-80 Hz).

all i can say is WOW. i am a pretty picky person when i come to audio. if it doesnt sound clean and loud. why bother. and this amp delivers. i have a alpine 12 type x and a 15 hooked up at four ohms and man does it pound. but i know i need a bigger altenator because this thing can pull 180 AMPS!!!!! my little 65 amp altenator just doesnt do it. i would recomend this amp to ANYONE who is competely serious about what they hear. and by the way. if you dont have a good ground hooked up this amp will almost immidiatly tear threw a electrical system and destroy the computer and whatnot. this is serious power
