Alpine R2-A75M

R-Series Mono Power Amplifier - RMS Power Ratings 1 x 750W @ 2 Ohms

The Alpine “R-Series” line of speakers, subwoofers and amplifiers have a heritage of sound quality you can hear from a block away, and the newly added R-Series amplifiers are no exception. Aside from their best-in-class performance, these amplifiers are tuned to emphasize the characteristics of the R-Series speakers and subwoofers, giving you that legendary R-Series experience. They have a 15% reduced footprint compared to the previous models and are easier to install.

If you like your music loud and clear, our R-Series R2-A75M mono amplifier is for you. It cleanly reproduces the bass in your music so you can enjoy the enhanced realism you want, even when you're playing High-Res music. Alpine has built some of its top-of-the-line amplifier technology into this R2-Series amp, including high-efficiency transformers, premium low-noise custom capacitors, and low-distortion dual "Sierra" feedback/correction circuitry.

The Alpine R2-A75M mono amplifier produces up to 750 watts RMS @ 2 Ohms, making it a perfect match for an Alpine R-Series subwoofer line. Advanced Class-D amp technology makes this powerful amp small enough to fit almost any location. 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-KNOB2 remote bass knob to control your bass from the dash.

R-Series amplifiers are available in two mono and a 4-channel configuration.
