Alpine MRX-M100

The Alpine X-Power MRX-M100 uses much of the same digital technology as the PDX series, achieving high efficiency with excellent audio performance, including low distortion, high damping factor and high S/N ratio. 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.

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. 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.

These digital powerhouses are so efficient, they’re much more compact than you expect. Advanced thermal protection means you can play them loud and the music never stops.
