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!

SUPERIOR SOUND

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. These speakers can 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.
