Concentrated power
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.
Tone control
Alpine included the tone controls you'll need to fine-tune your system so your speakers sound their best. You can use the high-pass filters to remove the extreme low bass from your full-range speakers, so they'll play more efficiently. If you plan on running subwoofers with your PDR-F50, you can adjust the low-pass filters and bass boost to get just the right bass tone.
Superior sound and build quality
Alpine built the PDR-F50 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-F50.
