KICKER went the extra mile to make these coaxials 100% marine-grade. Built from the ground up to be the best possible speaker for your boat, we added UV treatments to injection-molded cones and Santoprene surrounds. All KICKER Marine Coaxials meet or exceed ASTM standards for humidity and corrosion as well as for material degradation due to UV exposure. White and Charcoal Grilles included to match any boat’s attitude. Loud and clear, the KM Coaxial Marine Speakers are built to pump out the tunes – and the fun – for years to come! Whether you mount your speakers in the hull or in KICKER tower enclosures, you also get a pair of stout marine-grade grilles! LIGHT IT UP Our speakers are made to thrive in the water. UV treatments on injection-molded cones, Santoprene surrounds, baskets and grilles all help maintain top-shelf performance. KM speakers will endure almost any weather conditions with splash-and-spray-resistant sealed motors, cones and Locking/Sealed Terminal Covers. Speaker hardware is forged from rustproof, 316L stainless-steel.
