## Description

Bring the concert to the water with the MB Quart Marine Powersports Nautic 1-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 100dB, 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 a single audio channel and a maximum power of 400 watts, this audio receiver gives you quality audio wherever you go.

## Questions & Answers

**Q: Can this get wet?**
A: No.  The terminals and cooling vents are not waterproof.  What makes these amplifiers preferable for recreational vehicles is that they have pigtail connections versus exposed wore terminals offering some protection to liquid splashes, but by no means waterproof.

**Q: is it marine rated?**
A: Yes

**Q: Does this amp have speaker (high) level inputs?**
A: No.  RCA inputs only.  You will need a LOC to convert to low level outputs.

**Q: I have a 2018 polaris with ride command, will this amp connect to the ride command head unit?**
A: Not sure better check with Polaris
