Experience powerful, efficient bass with the Alpine R2-A75M mono amplifier, delivering 750W RMS into 2 ohms. Its next-generation Class D circuit and compact chassisā15% smaller than the previous R-A75Māmake installation easier without sacrificing performance. One-sided terminals and top-panel controls simplify wiring and tuning, while integrated mounting feet streamline the install. The amplifier maintains clean output with a signal-to-noise ratio greater than 75dB and a damping factor over 250 for tight, controlled bass. An optional remote bass knob (RUX-KNOB.2 or RUX-H01, sold separately) adds convenient level control from the driver's seat.
