MB Quart Marine Powersports Nautic Class D Amplifier w/ 2 Power Sports Speakers

Bring the concert to the water with the MB Quart Marine Powersports Amplifier and 2 Power Sports Speakers.

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 q-stasis stage reduces incoming noise from source units to improve the sound quality. 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.

The 2 speakers have 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 protection against sun fade, and remain musical in all weather conditions.

Get the sound you've been longing for during your fun activities with these MB Quart Marine Powersports Amplifier and 2 Power Sports Speakers.
