Kenwood KMM-BT38 Single DIN Bluetooth Digital Media Receiver

The Kenwood KMM-BT38 is a Single DIN digital media receiver for drivers who want modern phone, USB, and radio playback without a CD mechanism. It brings Bluetooth calling and streaming, front-panel USB and AUX inputs, and AM/FM radio to vehicles with a standard Single DIN radio opening. It is a practical upgrade for replacing an older factory radio or adding flexible media playback to a simple audio system.

Its built-in four-channel amplifier is rated for 50 watts maximum per channel and 22 watts per channel of full-bandwidth power at less than 1% THD. A 13-band equalizer, Digital Time Alignment, and Drive EQ provide useful adjustment tools for tailoring sound to the vehicle and listening position. The receiver can also serve as the control center for an amplified system through its front, rear, and subwoofer RCA preouts.

Bluetooth 4.2 supports hands-free calling and wireless audio streaming, with a supplied external microphone for voice communication. Dual phone connection makes it possible to switch between two connected phones, while KENWOOD Music Mix supports switching among up to five connected Bluetooth audio devices. The receiver also supports SBC and AAC Bluetooth codecs and common hands-free, phonebook, and remote-control profiles.

For wired playback, the front USB port works with compatible mass-storage devices and supports MP3, WMA, AAC, WAV, and FLAC files. USB charging is available at up to 1.5 amps, and the front AUX input provides a straightforward connection for analog portable audio sources. The 255-segment, 1.5-line text display and variable-color illumination keep key information visible while allowing the lighting to better suit the vehicle dashboard.

The KMM-BT38 is Amazon Alexa compatible when used with a supported smartphone, the Alexa app, and an active phone internet connection. It is also SiriusXM Radio Ready with an optional compatible SiriusXM Vehicle Tuner. With its shallow 3-15/16-inch chassis and three 2.5-volt preout pairs, it fits well in compact installations and offers a clear path to add external amplifiers or a powered subwoofer later.

Design & Installation

The KMM-BT38 uses a compact short-chassis receiver design with a detachable faceplate, front-facing connection ports, a 255-segment 1.5-line text display, and variable-color button illumination. The manufacturer does not specify faceplate or chassis material composition. Its removable faceplate can be detached for storage, while the compact 100 mm mounting depth can simplify fitment in vehicles with limited dash clearance.

This receiver is designed for a standard Single DIN dash opening and measures 182 x 53 x 100 mm (7-3/16 x 2-1/16 x 3-15/16 inches). The package documentation identifies a trim plate, mounting sleeve, wiring harness, extraction keys, faceplate, and microphone; vehicle-specific harnesses, dash kits, antenna adapters, steering-wheel-control adapters, and SiriusXM hardware may be needed depending on the vehicle and desired features. Use the front USB input for compatible media or device charging, connect external amplifiers to the front, rear, and subwoofer preouts, and use a compatible SiriusXM Vehicle Tuner if satellite radio is wanted.
