Bring the concert to the water with the MB Quart Marine Powersports 2-Channel 400-Watt Amplifier and 6.5-Inch 120W Coaxial Speakers.

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. 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 the 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 a peak power handling of 120 watts, RMS power of 60 watts, and an impedance of 4 Ohms, these bad boys know how to rock. They are protected from water, dirt, and UV rays, and remain musical in all weather conditions. Witness the smooth transition from high to low frequencies and fall in love with the award-winning midrange cones, titanium tweeters, and rust-resistant connectors.

Get the sound you've been longing for during your fun activities with the MB Quart 2-Channel 400-Watt Class D Amplifier and 6.5-Inch 120W 2-Way Coaxial Speaker Pair.
