Kicker KM12 12-Inch 2-Ohm Marine Subwoofer

The Kicker KM12 12-inch Marine Subwoofer is built for boat owners who want real bass performance on the water without sacrificing durability. Designed specifically for marine environments, the KM12 handles moisture, UV exposure, vibration, and harsh weather while delivering powerful low-frequency output that stays clean and controlled at speed. Unlike traditional car subwoofers, the KM Series uses marine-grade materials engineered for open-air environments where wind noise and engine noise normally kill bass response. Whether you are upgrading a wake boat, pontoon, fishing boat, center console, or yacht audio system, the KM12 provides the low-end performance needed to complete a serious marine audio setup. This 2-ohm marine subwoofer works best in sealed or ported enclosures and pairs perfectly with Kicker marine amplifiers for strong output and long-term reliability.
