Clarion Marine CMM-20 Source Unit is built tough for the sea, but easy on the ears—designed to deliver powerful, precise sound in any weather. This dual-zone marine stereo combines Bluetooth® streaming, AM/FM radio, and USB playback in a rugged IP66-rated housing that resists salt spray and blazing sun.

The 2.3-inch LCD screen provides clear readouts of settings and tracks, while backlit buttons ensure easy control even in the dark. A built-in 4 x 25 W RMS amplifier powers most marine speaker systems, and dual-zone audio lets you tailor sound independently between boat sections like the deck and helm.
