The new range of Class D car amplifiers from Alpine Car Audio take up a much smaller foot print than previous amplifier making them so much easier to install in tighter cabin and boot wells.
With speaker level inputs as standard these amplifiers allow you to continue to use your factory radio if need be without the need for expensive modifications or additional wiring looms. With smart remote sensing built into Alpine amplifiers they are compatible with newer European cars running CANBUS technology, this also means you spend less on expensive CANBUS and conversion looms when compared to other amplifier that do not feature this technology.
The Alpine MRX-M55 car amplifier features the latest thermal protection which provides for over voltage and over current detection allowing your amplifier to run longer under heavy loads without damage.
