The marine environment can be tough on a subwoofer. To make sure your sound stays strong for many seasons on the water, choose a sub that's been designed to handle these extreme conditions.

Kenwood's KFC-W254MRW 10" marine subwoofer has a strong, waterproof polypropylene cone with a rubber surround that'll hold up to humidity and UV exposure. A tough white plastic shell protects the basket and magnet against corrosion, and the sub's integrated white plastic grille matches the interior of many boats.

Kenwood designed this marine subwoofer for free-air use, so it'll produce great bass when mounted into a panel or bulkhead — no box required. Stainless steel mounting hardware is included.
