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.2 remote bass knob to control your bass from the dash.
