Alpine M-A120M 1200W Mono Marine Amplifier with IPX6 Waterproof Chassis

The Alpine M-A120M is a high-performance mono marine amplifier built to deliver powerful, controlled bass in demanding marine environments. Producing 1,200 watts RMS at both 2 and 1, or 600 watts RMS at 4, it provides flexible power for one or two compatible marine subwoofers.



Designed for life on the water, the M-A120M features an IPX6-rated waterproof chassis with salt, fog, and UV resistance, along with a watertight control cover and protective terminal boots. Adjustable low-pass and subsonic filters, a fully adjustable parametric EQ, and a gain-setting clip indicator make system tuning straightforward, while advanced thermal protection helps maintain reliable performance during extended listening sessions.
