Alpine MRX-F35 4chl Amplifier


The Alpine MRX-F35 X-Power amplifier draws on Alpine’s revolutionary PDX digital design that achieves high efficiency with audiophile level audio performance and rivalling signal-to-noise ratio. Plus, it’s extremely high dampening factor ensures uncompromised power and control of low frequency transients.

What’s more, the Alpine MRX-F35 has remote sense turn-on and speaker level input provides easy upgrading of factory systems.

Alpine MRX-F35 4chl 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 the Alpine MRX-F35 is ultra-compact, this digital powerhouse is engineered for robust no-shutdown performance and class-leading sound quality at an exceptional price.

Massive, Accurate Digital Power with an All-new Design

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.

Each Amplifier has sound quality that ranks as ‘best in class’

These Amplifiers inherit PDX ideology and technology, which means they offer performance unrivalled in their class. They are outstanding in terms of low noise, low distortion and high damping factor, for excellent and reliable sound quality.

High operational reliability

Power is reduced under conditions of extreme head or load to keep the music playing without interruption. A multi-stage power limiting circuit minimises the audible effects until conditions improve. A major advantage for those who like their music loud.


Outstanding system integration

These amps have numerous tuning features and can be installed in a wide variety of system configurations. No matter what the desired system, optimum installation and sound tuning are easily achieved.

All digital lineup

The X-Power series uses much of the same digital technology as the PDX series, achieving high efficiency with excellent audio performance, including low distortion, high dampening factor and high S/N ratio.


Easily upgrade any system

Speaker level inputs let you connect these amps directly to factory-installed head units that do not have preamp outputs, so you can upgrade the original system with higher power and better speakers.


Remote sensing

The remote sensing function turns the power on automatically when the amp detects an incoming audio signal. There is no more need for an extra remote line.

Smaller footprint

PDX digital technology means high efficiency, so the X-Power amps are up to 29% more compact than previous models, making installation even more convenient.


Effective heat protection

If interior heat reaches unacceptably high levels, a thermal protection circuit decreases power in two steps rather than interrupting the music. It also provides over-voltage and over-current protection.


Remote control bass knob (RUX-KNOB)

Simply add the RUX-KNOB (sold seperately) and get full control from the dash for instant bass adjustment. You also get the ability to control mulitple amps from just one controller with simple telephone cord adapters. Only for mono and 5 channel amps.
