The Kicker 51MSS65 MSS65 6.5 inch marine coaxial speakers bring together premium audio engineering and true marine-grade durability. Designed to outperform standard marine speakers, they provide cleaner detail, tighter midbass and a more natural vocal range—ideal for open cockpits, helm stations, cabins and deck spaces.
Each speaker uses a carbon-fibre infused polypropylene cone paired with a tough Santoprene surround for exceptional rigidity and control. This keeps midrange and midbass tight and accurate even at high volume when the boat is moving at speed. A high-performance Tetoron textile dome tweeter delivers clear, smooth highs without harshness, helping voices, instruments and high-frequency detail cut through engine noise and wind.
Kicker’s Real Marine build ensures the MSS65 can withstand long-term UV exposure, heavy salt fog, spray and consistent washdowns. Glass-filled nylon baskets, sealed motor assemblies, stainless steel hardware and marine-rated terminals all contribute to a long lifespan in harsh boating conditions.
With 75W RMS (150W peak) power handling at 4 ohms and high efficiency, the MSS65 speakers work brilliantly with modern marine amplifiers or a quality head unit. They fit most 6.5" factory speaker locations, making installation straightforward for boat upgrades or full system builds.
Supplied in charcoal (dark) grilles, with optional matching white grilles available separately.
