Features:

Alpine's X-Power MRX-F65 4-channel amplifier uses the latest in amp technology to play your music loud and clean without taking up much space. And this compact amp employs some of the same circuitry developed for Alpine's top-of-the-line PDX digital amps so it'll bring exceptional sound to your ride.

The MRX-F65 puts out 110 watts RMS per channel, so you'll have plenty of clean power to fill your listening space with music. You can even use it in 2-channel mode to drive a pair of subs with 320 watts each. Onboard frequency filters let you tailor the output to fit your setup, and a bass boost on the rear channels helps to fatten up the sound.

A power management system optimizes the amp's performance and keeps the music playing, even when you're pushing it hot and hard for a long time. Speaker-level inputs with an automatic turn-on feature simplify system hook-up.
