The latest marine stereo from Polk Ultramarine offers a full range of the latest advancements in audio features and control. The UM2 is the first Polk Ultramarine stereo to offer four-zone capability with the separate POLK DSP module. This gives boaters independent volume control of up to four different areas of the boat, from the helm to tower speakers, so every rider has the perfect listening experience.

The waterproof and UV/corrosion resistant stereo was engineered in a two-piece modular design to give manufacturers more flexibility for installation when space is a concern. The commander can be mounted on the dash while the module can be easily installed out of sight. The stereo features a 4.3” full-color TFT display and Bluetooth connectivity that allows boaters to stream their favorite tunes and control their music right from any smart device.

The Polk Ultramarine app, available for both Apple and Android devices, turns any smart phone or tablet into the ultimate wireless remote control. This stereo is also compatible with either the PRC100BC or PRCZ200BC wired remotes from Polk, sold separately.

The UM2 offers Sirius XM radio, USB 2.0 for MP3 and WMA playback, 18 FM and 12 AM presets, and seven-channel NOAA weatherband radio.
