Alpine PDR-F50 4-Channel Car Amplifier

Alpine managed to pack more power per square inch into their PDR-F50 4-channel Power Density Reference amplifier than almost any other amp in its class. The PDR-F50 can put out 85 watts RMS per channel, giving extra clarity and volume to your full-range speakers, and it'll fit in almost any of the tiny spaces you find in many cars and trucks these days. You can also use this versatile amp in 3-channel mode, driving your speakers with the front channels, and bridging the rear channels to send up to 250 watts RMS to your sub.
