ALPINE Mono subwoofer amplifier — 250 watts RMS x 1 (MRVM250)
Alpine makes it a little easier to get great sound in your vehicle, with their V-Power Series MRV-V500 amplifier. This 5-channel powerhouse can put out 40 watts RMS to four full-range speakers and up to 250 watts RMS to a subwoofer, and still fit into the tight spaces you find in many cars and trucks these days. You can also use this versatile amp in 3-channel mode, driving a pair of high-performance speakers with 120 watts each, while still sending 250 watts to a sub.

Thermal protection without annoying shut-downs
The MRV-M250 uses a technology called Enhanced Shutdown Performance, which rolls back the output a bit when the amp threatens to overheat from playing at its limits too long. Instead of shutting down completely, it continues playing your music, until it cools enough to return to full power.
A low-pass filter puts you in command of the frequencies that reach your sub, while a bass boost lets you apply plenty of low-end punch. The amp includes preamp- and speaker-level inputs, so you can install it in almost any vehicle, even one with a factory radio. If you're using the speaker-level inputs, the amp senses an incoming signal and turns itself on, eliminating the need to run a turn-on wire run back to your vehicle's receiver or fusebox. You can control the volume of your MRV-M250 from the front seat with the optional RUX-KNOB remote bass controller.
