45KMF124 12" 4-ohm Free-Air Marine Subwoofer

Marine Material

Completely weatherproof, these 10 and 12-inch Marine Subs are real-world tested for salt/fog and UV exposure, meeting or exceeding ASTM standards.

Bass That Lasts

A completely sealed motor structure and locking/sealed terminal cover make it splash-proof for long life, while a tough Santoprene® surround and marine grade cone pump out the bass, no matter how long or loud you want the party to be.

Light Show

Optional LED grilles (sold separately) for KM Subs come with seven selectable LED colors to match your boat’s theme! Add the KMLC LED controller (sold separately) for 20 total colors and 19 different lighting modes to make it even more fun!

Bump the Boat

Packed with features and made for marine, KICKER gives you the deep, loud bass your boat needs with the KMF series of subs.
