About this product
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 2Ω and 1Ω, or 600 watts RMS at 4Ω, 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.
