The Alpine R2-A75M mono amplifier is engineered to elevate your car audio experience with its powerful 750W output at 2 ohms. Built with Alpine's advanced Class D amplifier circuit, it ensures high sound quality and efficient operation. This next-generation R-Series amplifier offers a significant improvement in performance while maintaining a sleek and compact design. Designed for convenience and simplified installation, the R2-A75M boasts a 15% smaller footprint compared to its predecessor. It features a one-sided terminal layout for easy access to speaker connections and top-panel sound controls for quick adjustments to gain and crossover settings. Integrated mounting feet further streamline the installation process in various vehicle applications. This amplifier delivers 500W RMS x 1 at 4 ohms and 750W RMS x 1 at 2 ohms, with a frequency response of 10Hz – 400Hz and a damping factor greater than 250. The product includes essential mounting hardware, an owner's manual, and a "birth sheet" certifying the amplifier's actual power output. An optional remote bass knob (RUX-KNOB.2 or RUX-H01) is compatible but sold separately.
