KICKER KM8 8-Inch Marine Coaxial Speakers with LED – 150W RMS, 4-Ohm

All-weather audio for your vessel

The KICKER KM8 8-Inch Marine Coaxial Speakers bring rugged sound to the open water. Built from the ground up for marine use, the cones are UV treated and paired with flexible Santoprene surrounds. This combination helps the woofers maintain movement and control even in challenging sunlight and humidity, so your music stays steady when you need it most.

With a 4 ohm impedance and 150 watts RMS of continuous power (300 watts peak) per pair, KM8 coaxials are designed to deliver clear, balanced sound across the cockpit, bow, or transom. The 1-inch tweeters add crisp upper frequencies to keep vocals and details from getting washed out by wind and waves. The result is a sound profile that bridges casual listening and outdoor entertaining without demanding a specialized amp.

Durability meets decoration

These speakers are designed to withstand marine conditions while looking great on deck. They pass ASTM standards for humidity and corrosion, and their marine-grade hardware resists the wear that comes with sun, spray, and salt spray exposure. White and charcoal grilles are included to match a range of boat aesthetics, letting you tailor the look as you upgrade your system.

LED lighting for mood and visibility

Sweet LEDs let you choose from seven colors right out of the box. For even more color options and lighting modes, you can pair the KM8 with the optional KMLC LED controller to unlock up to 20 colors and 19 lighting modes, offering a customizable ambiance for evening cruises or dockside gatherings.
