You get big power from a small package with Alpine's PDX Series amplifiers. Super-efficient Class-D technology allows these pint-sized powerhouses to run cool, so they can be stacked together in a multi-amp setup, freeing up valuable space in your car.

New Five-channel Amplifier
All-new five-channel design allows you to build a total system using only one PDX amplifier.

High Power, High Sound Quality
PDX amplifiers deliver exceptionally accurate and clear sound with high power. The advanced power supply, Class-D design, and switch-mode digital amplification allow these amps to stay extremely efficient at all power levels.

Small Footprint
For all the sound they put out, the PDX amps are incredibly compact - packing huge amount of power in a tiny amount of space for maximum installation flexibility.
