The CMM-30 is a weatherproof, marine source unit with advanced audio features and a multi-source, multi-zone design for outstanding audio performance.

Equipped with a wide range of audio source options, the CMM-30 features a global, digital AM/FM tuner with built-in NOAA weather radio (US only), SiriusXM-Ready® (tuner, antenna, and subscription sold separately), Bluetooth® audio streaming, a USB 2.0 input for playback from your USB storage device (with 2.1A charging) and an analog auxiliary input, all designed to deliver non-stop sound, no matter how choppy the seas may get.

A rugged, weatherproof (IP66 rated) chassis houses a 3-inch (76 mm) full-color, LCD display with dimmable control for nighttime viewing. When in motion, you'll appreciate the large controls and uncluttered user interface with big text and backlit buttons.

Ultra-versatile zone controls and audio features include a rock-solid, onboard amplifier, capable of powering your speakers with 100 watts (25W RMS x 4 @ 4 ohms) of high-fidelity sound to two main zones, as well as eight channels of top-quality preamp outputs (3.5V RMS), with selectable Zone 4 or subwoofer functionality. Customize your sound using the built-in 5-band equalizer or with onboard the tone controls (Bass/Mid/Treble).
