Alpine Authorized Online Dealer

If you like your music loud and clear, Alpine's R-Series R2-A150M 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-A150M mono subwoofer amplifier produces up to 1,500 watts RMS, making it a perfect match for a pair of Alpine's R-Series subwoofers. 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-KNOB.2 remote bass knob to control your bass from the dash.
