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. ^^ Sweet LEDs! You get a choice of seven colors to make your boat shine, or add the KMLC (sold separately) LED controller to unlock 20 colors and 19 wild lighting modes! ^^ Continuous Power Handling (Watts RMS) - 150, Peak Power Handling (Watts) - 300 ^^ White and Charcoal Grilles included to match any boat's attitude.
