MB Quart Marine Powersports Nautic 1 Channel 400 Watt Class D Amplifier, Black
Description
Take your marine audio experience to the next level with this mono-channel waterproof boat amplifier, engineered for durability, power, and crystal-clear sound. Designed with marine-specific connectors and built to withstand extreme weather conditions and salt spray, this amp ensures reliable performance season after season. With a maximum power output of 400 watts and RMS ratings of 1 x 400W at 2 ohms and 1 x 200W at 4 ohms, it delivers the strength and clarity your music deserves, even on the open water.
Built to meet IPX water-resistance standards, you can confidently enjoy your favorite playlists without worry. A low-noise preamplifier circuit maintains sound purity while maximizing power efficiency, preventing distortion for premium audio quality. The RCA nickel-plated connectors are both high-temperature and impact-protected, providing secure and long-lasting connections.
Enjoy full control with the LPF (Low Pass Filter), essential for setups using multiple amplifiers, while the aluminum heatsink and Simpatico coil design with PWM power supply ensure consistent voltage and quick heat dissipation. For added convenience, quick-disconnect wires and RCA connections simplify seasonal removal, and built-in thermal, overload, and short-circuit protection with illuminated indicators provide peace of mind for every voyage.
