About the Alpine R-A75M

For loud and realistic-sounding bass

Alpine's R-Series R-A75M amplifier cleanly reproduces the bass in your music so you can enjoy the enhanced realism you want in your vehicle, even when you're playing high-res music. They've applied some hot technology from their top-of-the-line X-Series amplifiers into this R-Series amp. This includes the use of high-efficiency transformers and premium custom capacitors in the amp's construction. Dual "Sierra" feedback circuitry decreases distortion by correcting the output using the original input signal.

How much power?

The R-A75M mono subwoofer amplifier puts out up to 750 watts RMS, conveniently and perfectly matching the power ratings of Alpine's R-Series subwoofers. Advance Class D amp technology allows this amp to be built so small it'll fit in almost any of the tiny spaces available in many cars and trucks these days. You can adjust the amp's low-pass filter, bass boost, and subsonic filter to get just the right bass tone. Plus, you can add the optional RUX-KNOB.2 remote bass knob to control your bass from the dash.
