Alpine MRD-M300 150W x 1 Mono Subwoofer Amplifier

Gut-busting power and exacting control. That's what you get with Alpine's V12 AccuClass-D mono bass amplifiers. The MRD-M300 has a built-in digital signal processor that lets you control the Bass Engine® features with surgical precision, giving you a level of fine-tuning capability normally found only in Alpine receivers.

Set the cut-off point for the subsonic filter from 15-50 Hz (in 5 Hz steps) and use the digital parametric EQ (which allows you to control the width of the equalization curve, as well as the center point) to improve overall sound.

The Bass Compensator uses Alpine's MediaXpander (used in their receivers to optimize playback of compressed media files) to enhance low-end definition of the amplifier's output. Monitor the temperature, voltage, and current levels using the digital readout.

Alpine's digital technology ensures extraordinary clarity. The efficient Class-D design lets your music sound like thunder without wasting a lot of energy as heat, while the lightning-fast MOSFET power supplies keep your music roaring with life.

The MRD-M300 has speaker-level inputs so you can easily use it with any car stereo. Hook it up and hear what good bass can sound like!
