KICKER KMF124 12-inch Marine Subwoofer with LED White Grille – 4 Ohm, Free Air

Powerful, Open-Air Bass for Your Boat

The KICKER KMF124 12-inch marine subwoofer brings deep, confident bass to open-air boat setups without the need for a dedicated enclosure. Built for the harsh marine environment, it combines a weatherproof design with a sealed motor and splash-proof terminal cover for long-lasting performance on the water. The matching white LED grille adds a stylish touch that shines in both day and night conditions, making your marine audio setup stand out as you cruise.

Designed to handle real-world marine use, this sub delivers a robust low end across a wide frequency range (30–500 Hz) with a 4-ohm voice coil, rated at 175 W RMS (350 W peak). The speaker’s large ceramic magnet and corrosion-resistant components are paired with a tough Santoprene surround and a marine-grade polypropylene cone, delivering loud, low-frequency punch even when the action heats up at full volume.
