Alpine PDR-F50 4 Channel 4 x 85W RMS

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.
