About the Alpine R2-A75M: 750 W R2-Series Monoblock Amplifier
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 resolution music. Alpine has built some of its top of the line Amplifier technology into this R2-Series Amplifier, 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 W RMS @ 2 ohms, making it a perfect match for an Alpine R-Series subwoofer line. Advanced class-D Amplifier technology makes this powerful Amplifier small enough to fit almost any location. You can adjust the Amplifier'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.
