Alpine R2-A75M


Elevate Your Radio

Elevate your audio with the Alpine R2-A75M Mono Amplifier - delivering powerful 750W performance in a sleek, compact design. Built with Alpine's cutting-edge Class D Amplifier Circuit, this next-generation R-Series amp offers exceptional sound quality and efficiency, making it the perfect addition to any car audio system.
