Features & Benefits

Built-in DAB+ Digital Radio Superior digital radio reception provides crystal-clear audio quality eliminating static and interference typical of AM/FM broadcasts. Includes DAB+ antenna simplifying installation and ensuring optimal reception quality for digital radio stations.

Amazon Alexa Integration Voice control enables hands-free operation of music playback, navigation queries, and compatible smart vessel systems. Alexa integration keeps hands on helm while accessing information and entertainment maintaining safe vessel operation.

Mechless Design Eliminates CD mechanism reducing mechanical failure points and improving reliability in marine environments. Mechless construction removes components prone to salt corrosion, moisture damage, and vibration failure common in marine applications.

IPX5 Water Resistance Water resistance rating protects against water jets and splashes from vessel operation, weather exposure, and washdown. IPX5 certification ensures reliable operation in typical marine water exposure scenarios exceeding splash resistance of standard electronics.

Conformal Coating Protection Circuit board coating provides marine-grade protection against moisture, salt spray, and corrosive conditions. This specialized coating prevents electrical shorts and corrosion extending headunit lifespan in harsh marine environments where standard car audio fails.

Wireless Remote Control Included remote enables audio system operation from various vessel locations such as swim platform, cockpit, or cabin. Wireless control improves convenience during docking, entertaining, or vessel activities away from helm station.

High-Power Amplifier Built-in amplifier delivers robust output to marine speakers without requiring external amplification. Internal amplifier simplifies system design and reduces installation complexity for smaller vessels or basic audio system requirements.

Built-in Bluetooth Wireless connectivity enables music streaming from smartphones and tablets plus hands-free calling. Bluetooth eliminates cable clutter and water intrusion risks associated with auxiliary cables while maintaining communication during vessel operation.

Multi-Color Illumination Customizable display lighting matches boat dash instrumentation creating cohesive appearance. Choose from multiple colors coordinating with existing lighting schemes improving nighttime visibility and aesthetics.

Short Chassis Design Compact depth simplifies installation in tight marine dash spaces with limited clearance. Short chassis accommodates marine consoles and dash configurations where standard DIN depth creates mounting challenges or interference with vessel structures.

Technical Specifications

Installation & Compatibility

Marine Application Compatibility The KMR-M508DAB fits standard DIN-sized dash openings in boats, pontoons, sailboats, and marine vessels. IPX5 water resistance and conformal coating withstand harsh saltwater environments. Verify dash opening dimensions match standard DIN size (178mm x 50mm) before purchase.

DAB+ Antenna Installation Mount included DAB+ antenna in location with clear sky view for optimal reception. Marine antenna mounting requires consideration of vessel movement, salt spray protection, and lightning safety. Route antenna cable through protected channels avoiding pinch points and water exposure.

Mounting Requirements Short chassis design accommodates tight marine dash spaces with limited depth clearance. Measure available depth behind dash ensuring adequate clearance for wiring connections and rear chassis. Marine mounting sleeves or brackets may be required depending on dash construction.

Wiring and Connections Use marine-grade tinned copper wire for all power and speaker connections. Connect power through appropriate fusing protecting headunit and vessel electrical system. Route wiring through protected channels avoiding areas with water pooling or spray exposure. Use heat shrink connectors and dielectric grease on all connections.

Alexa Setup Install Kenwood remote app on compatible smartphone and enable Alexa functionality. Pair smartphone via Bluetooth following on-screen prompts. Configure Alexa settings including wake word and connected services. Voice control functionality requires active smartphone connection.

Speaker Connections Connect speakers observing correct polarity ensuring proper phase relationship. Use marine-grade speaker wire with appropriate gauge for cable length and power levels. Internal amplifier provides adequate power for most small to medium vessel installations.

System Testing Test all functions including DAB+ radio reception, Bluetooth streaming, voice control, and wireless remote operation. Verify water resistance by inspecting faceplate seal and connection points. Test hands-free calling confirming clear audio in both directions accounting for engine and wind noise.

Frequently Asked Questions

What is DAB+ and why is it better than AM/FM?

DAB+ is digital radio broadcasting providing superior audio quality compared to traditional AM/FM. Digital transmission eliminates static, interference, and signal fade delivering consistent crystal-clear sound. DAB+ also provides additional station information, pause/rewind functionality, and more stations in same bandwidth.

Is this waterproof enough for open cockpit installation?

The IPX5 rating protects against water jets and splashes from normal marine operation and washdown but is not submersible. Install in dash location with some protection from direct water spray. The rating handles typical marine water exposure including rain, spray, and washdown better than standard car audio.

How does Amazon Alexa work on a boat?

Alexa integration requires smartphone with Kenwood remote app and active data connection. Voice commands control music playback, request information, operate compatible smart boat systems, and access Alexa skills. Smartphone must be paired via Bluetooth and within range for voice control functionality.

Can I add external amplifiers?

Yes, the headunit provides two pairs of preout connections at 2.5 volts for external amplifiers. Connect front and rear amplifiers or use one pair for subwoofer amplifier. The lower 2.5V output may require gain adjustment on amplifiers compared to higher voltage preouts.

Is the wireless remote waterproof?

Wireless remote should be protected from direct water exposure and stored in dry location when not in use. While designed for marine environment, remote is not waterproof and prolonged water exposure can cause damage. Use in protected areas and store safely after use.
