The KICKER® KMF 12-inch Marine Subwoofer makes serious bass without a dedicated enclosure! Made to take the power and the weather, this sub is custom made to bring the bass on your boat.

This 12-inch KMF Freeair Marine Subwoofers transform your boat into a bass machine! Mount these versatile subs nearly anywhere – no enclosure needed.


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


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.


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!
