Powerful, realistic bass
If you like your music loud and clear, Alpine's R-Series R2-A75M 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.
How much power?
The R2-A75M mono subwoofer amplifier produces up to 750 watts RMS, making it a perfect match for an Alpine R-Series subwoofer. Advanced Class D amp technology makes this powerful amp small enough to fit almost any location.
