Kicker KM42

Hear them 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 KICKER tower enclosures, you also get a pair of stout marine-grade grilles! Kicker's 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 and locking/sealed terminal covers. Speaker hardware is forged from rustproof, 316L stainless-steel.
