500W RMS MM-Series 4-Channel Marine Amplifier

The Memphis MM500.4V is a high-performance, Class D 4-channel amplifier specifically engineered for the rigors of marine and powersports environments. A step up from standard mobile amplifiers, the MM-Series features an IPX5-rated sealed chassis, conformal-coated circuit boards, and waterproof quick-disconnect connectors to prevent damage from salt, moisture, and vibration. Its "installer-friendly" design includes single-sided terminals and a removable power lug, making it much easier to mount in the tight, often awkward compartments found on boats and UTVs.

The MM500.4V is highly versatile, delivering 80 Watts RMS x 4 at 4 ohms or 125 Watts RMS x 4 at 2 ohms. For those looking to power a pair of subwoofers or high-output mid-bass drivers, it can be bridged to provide 250 Watts RMS x 2 at 4 ohms. The amplifier features sealed top-mounted controls for easy tuning even after installation, and it includes advanced signal-sensing technology for automatic turn-on when using factory head units without a dedicated remote wire.
