Marine subwoofer for infinite-baffle fit

The Alpine MRN-W10S4-LW is a 10-inch marine subwoofer built for infinite-baffle mounting in boats or outdoor venues. Its carbon fibre hybrid cone and 20 mm X-Max deliver deep, accurate bass while the IPX6 rating, ASTM B117 salt-fog and ASTM G154 UV tests confirm durability in harsh conditions. White finish suits bright exteriors.

600 W RMS headroom and peak limits

Continuous power handling sits at 600 watts RMS with 1800 watts peak capacity, giving ample headroom for extended high-output passages. The infinite-baffle design relies on the enclosure air volume for control, so output drops if the cavity is too small or leaks. Installers needing sealed-box alignment will find this model unsuitable.

RGB grille and Amphenol plugs simplify install

A unique grille integrates RGB LED lighting for visual effect without separate fixtures. Waterproof Amphenol connectors on both the speaker and LED circuits remove the need for custom weather-sealing, cutting installation time and failure points. No amplifier, wiring kit or controller is bundled, so those must be sourced separately.

Questions about this item

Can this 10-inch subwoofer run on an older marine amplifier that delivers less than 600 watts RMS?

Yes, the subwoofer will operate with lower-powered amplifiers; match the amp's RMS output to the subwoofer's 4-ohm impedance and set gains conservatively to avoid clipping.

How can I confirm the carbon fiber hybrid cone and RGB LED grille are functioning correctly after installation?

Play a low-frequency test tone at moderate volume to verify clean cone excursion up to 20 mm, then cycle the LED controller through each colour to ensure the integrated grille lighting responds.

Does the box include the waterproof Amphenol plugs for both the speaker and LED connections, or must they be purchased separately?

The subwoofer ships with the waterproof Amphenol connectors pre-fitted to the speaker leads and the LED harness; no additional connectors are required for installation.
