Alpine MRX-M55 X-Power Mono Amplifier

Product Description

MRX-M55 X-Power Mono Amplifier

The all-new digital X-Power series of Class-D amplifiers incorporate even further advancement of Alpine’s digital technologies used in our top-of-the-line PDX series for greater power and improved sound quality. Whilst ultra-compact, these digital powerhouses are engineered for robust no-shutdown performance and class-leading sound quality at an exceptional price. What’s more, their remote sense turn-on and speaker level input provides easy upgrading of factory systems.

X-Power amplifiers draw on Alpine’s revolutionary PDX digital design that achieves high efficiency with audiophile level audio performance and rivalling signal-to-noise ratio. Plus, their extremely high dampening factor ensures uncompromised power and control of low frequency transients.

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.
