Efficient digital powerhouses

2 Channel Digital Amplifier - MRX-T17

The new X-Power amplifiers are now all digital. The successors of Alpine’s popular V-Power series, they employ various PDX amp technologies for impressive power and bass performance. 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.

Technology
Product information

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 damping 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 overcurrent protection.
