The KICKER® KMF 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. Completely weather-resistant, these marine subs are real-world tested for salt/fog and UV exposure, meeting or exceeding ASTM standards for marine durability. 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 polypropylene cone pump out the bass, no matter how long or loud the party lasts. Packed with features and made for specifically for marine use, KICKER gives you the deep, loud bass your boat needs.
