Kenwood KMR-M332BT Single DIN Marine Digital Media Receiver

The Kenwood KMR-M332BT is a Single DIN marine and motorsports digital media receiver designed for systems where Bluetooth streaming, radio, and USB playback are more useful than a CD mechanism. It provides a compact source-unit upgrade for boats, off-road vehicles, motorcycles, and conventional 12-volt vehicle installations. Its front-panel USB and auxiliary inputs give users straightforward access to portable music sources.

Built-in Bluetooth supports hands-free phone calls and wireless audio streaming, helping keep a compatible smartphone accessible without relying on a wired connection. KENWOOD Music Mix allows up to five Bluetooth devices to be connected, while Dual Phone Connection lets users switch between two phones. The KENWOOD Remote app can also control basic receiver functions from a paired iPhone or Android smartphone.

The KMR-M332BT uses a 13-band equalizer, Digital Time Alignment, and Drive EQ to tailor playback for the listening position and compensate for road or engine noise. Its internal amplifier is rated at 50 watts maximum per channel and 22 watts per channel of full-bandwidth power at less than 1% THD. Three 4.0-volt preouts provide a cleaner signal path for adding external amplification or a powered subwoofer.

For digital music libraries, the front USB input supports MP3, WMA, AAC, WAV, and FLAC files. FLAC playback is supported up to 24-bit/96 kHz, making it suitable for users who keep higher-resolution music files on a compatible USB drive. The receiver also includes AM/FM radio and is SiriusXM Radio Ready when used with a compatible optional SiriusXM tuner.

This receiver is built for exposed-use environments with a conformal-coated circuit board that improves moisture resistance and helps prevent corrosion. The 255-segment, 1.5-line text display uses variable-color illumination, allowing the lighting to be adjusted to complement a dash or helm. A short 3-15/16-inch chassis depth helps make room behind the mounting location in compact dashboards and consoles.

Design & Installation

The KMR-M332BT has a compact Single DIN chassis, a 255-segment 1.5-line text display, and variable-color LED illumination. Its conformal-coated circuit board is intended to improve resistance to moisture-related corrosion. The front USB and AUX connections keep commonly used media inputs within easy reach.

Installation requires a 12-volt negative-ground electrical system and a dashboard or console opening that accepts a Single DIN receiver. The unit measures 7-3/16 inches wide by 2-1/16 inches high by 3-15/16 inches deep; a trim plate and mounting sleeve are included. Use the supplied microphone for Bluetooth calling, connect 4- to 8-ohm speakers directly, or use the RCA preouts when integrating external amplification.
