Mono subwoofer amplifier — 650 watts RMS x 1 at 2 ohms


Concentrated power

Alpine managed to pack more power per square inch into their PDR-M65 mono Power Density Reference amplifier than almost any other amp in its class. The  PDR-M65 can put out up to 650 watts RMS, giving solid punch and definition to your bass, and it'll fit in almost any of the tiny spaces you find in many cars and trucks these days. You can adjust the amp's low-pass filter and bass boost to get just the right bass tone, and you can add the optional RUX-KNOB remote bass knob to control your bass from the dash.

Superior sound and build quality

Alpine built the PDR-M65 to exacting physical and electronic standards, resulting in a tough, powerful amp with an incredibly clean and noise-free output. All the electrical connections are made on one side, for more convenient and neat installations. Speaker-level inputs allow you to use this amp in almost any system, even one with a factory radio. And you can rotate the badge, so the Alpine logo can always display right side up no matter which way you mount your PDR-M65.
