Bring the concert to the water with the MB Quart Marine Powersports Nautic 2-Channel 400-Watt Class D Amplifier. This powerful, versatile amp is built to IPX standards to resist water while delivering crisp, clear audio.

Durable and well-built, the amplifier resists extreme weather and salt spray, letting you enjoy quality audio out on the water. A low-noise preamplifier circuit maximizes power at low voltage to produce clear music audio with minimal distortion. With a signal-to-noise ratio of less than 90dB, you can listen to your favorite tunes without interruption in quality. Prewired inputs connect via RCA-nickel plated terminals that are high temperature and impact protected to provide secure connections. The PWM MOSFET power supply provides stable power through PC board with minimal heat generation and the aluminum heatsink dissipates heat quickly to allow the amp to run on lower impedance for a longer duration.

With 2 audio channels and a maximum power of 400 watts, this audio receiver gives you quality audio wherever you go. Enjoy your favorite tunes out on the water no matter whether using the Nautic Marine 2-Channel Waterproof Amplifier by MB Quart.
