Introducing the new digital X-Power series of Class-D amplifiers. The X-Power amplifiers incorporate many of Alpine’s PDX advanced digital technologies at an affordable price. Don’t let their small size fool you, these amplifiers were specifically engineered to offer performance, sound quality and reliability at PDX standards.

Dual-Feedback Modulation Loop
When playing music, a clean, distortion-free, low-power signal input to an amplifier should exit as an identical high-power output signal to drive your speakers. In reality, most amps don’t even come close to this ideal, instead adding significant audible distortion especially in the high frequencies, which earned typical Class-D amplifiers a deserved reputation for bad sound. The X-Power’s Global Modulation with Adaptive Feedback Control loop circuitry intelligently assures the power output is as clean and distortion-free as possible. Their real-time error-correction analyzes the signal not only once, but twice by comparing input signal with the output throughout the entire amplification process. In doing so, X-Power amplifiers ensure that their output signal delivers a clean, clear and powerful sound that must be heard to be believed.

Small, Powerful Design
The new X-Power series amplifiers have decreased in size, up to 15% smaller than V-Power and yet they pack in much more flexibility, durability and sound quality.

Versatile Controls and Adjustments
Their small size and versatile controls allow the X-Power amplifiers to easily be added to either an aftermarket or factory system and can be setup to accommodate a variety of system configurations. With a 4-channel non-fading speaker input connection, hooking up to your factory-installed system is a breeze via speaker-level input. Also, the pre-out is buffered (mono models) to allow for additional amplifiers to be added without the need for splitters, maintaining signal quality and helps simplify installation in big bass systems. Speaking of big bass, all MRX Mono models are also equipped with a subsonic filter, to keep inaudibly low power-wasting noise out of your subwoofer system.

Remote Control Bass Knob
Adjust subwoofer level without having to access the amplifier itself. Simply add the RUX-KNOB (sold separately) and get full control for remote on-the-fly bass adjustments. You also have the ability to control up to ten X-Power mono amps from just one RUX-KNOB controller with simple telephone jack adapters. The RUX-KNOB is compatible with all Mono and 5-channel X-Power models.
