The Alpine R2-A75M mono car amplifier reproduces low frequencies and delivers up to 750 W RMS at 2 Ohms. Class D amplification helps keep its size compact, while high-efficiency transformers, low-noise capacitors, and dual “Sierra” correction circuits help reduce distortion.
The GAIN level, variable low-pass filter, subsonic filter, and bass boost are adjusted using the controls on the top panel. The speaker-level input supports automatic turn-on, and the amplifier is compatible with the optional RUX-KNOB2 bass controller.
