Alpine MRX-M240 2400w Mono Amp

2400 watt X-Power Mono Amplifier


Categories: ,


The X-Power amplifiers employ various PDX amp technologies for impressive power and bass performance. Their glossy black finish gives them a high-tech, professional appearance.

Extremely efficient operation makes these digital powerhouses much more compact than you expect. Advanced thermal protection means you can play them loud and the music never stops.

Add the RUX-KNOB (sold separately) and get full control from the dash for instant bass adjustment. You also get the ability to control multiple amps from just one controller with simple telephone cord adapters.
