The Boss Audio 6"x 9" MR690 oval speakers deliver 350 watts of marine-grade audio performance built specifically for the harsh saltwater environment. These waterproof marine speakers are engineered to survive the corrosion, UV exposure, and moisture that challenge standard audio equipment on the water. Every component—frame, grill, surround, and cone—is constructed from waterproof polymer composite materials with UV-protective coatings, while tinsel leads receive corrosion-resistant treatment to ensure long-term reliability in salt air and spray conditions.
The 6"x 9" oval format fits standard marine mounting locations found on most boats, while the 350-watt power rating delivers sufficient output for cabin, cockpit, or deck use without requiring external amplification for typical recreational boating volumes. Polypropylene cones provide reliable mid-range reproduction with the durability needed for outdoor use, and the cloth surrounds maintain structural integrity across temperature fluctuations and extended UV exposure. The white finish integrates with typical marine aesthetic while the waterproof construction eliminates concerns about speaker failure from spray, rain, or accidental water contact during cleaning or rough conditions.
These marine oval speakers suit weekend fishermen, cruisers, and offshore anglers who need reliable cabin audio without the expense of full custom marine audio systems. They work equally well for retrofit installations on existing boats or new build-outs where standard 6"x 9" speaker locations are present. The 350-watt rating and weatherproof design make them practical for vessels operating in saltwater, freshwater, or both, eliminating the premature failure typical of automotive or consumer speakers exposed to marine conditions. Installation in helm stations, cabin ceilings, or transom locations provides consistent performance season after season without the corrosion and degradation that forces replacement of non-marine rated audio equipment.
