BOSS Audio Systems MRGB55W 5.25-In Marine Speakers | Weatherproof, 150W per Pair

Meet the BOSS Audio Systems MRGB55W 5.25 inch marine speakers — a compact, weatherproof option designed for boats, pontoons, and RVs. With a total of 150 watts per pair and adjustable RGB illumination, these two-way, full-range speakers are built to blend performance with style on board or dockside.

Durable build for on-water listening

The MRGB55W pair uses a polyurethane cone that stays rigid under pressure, helping maintain accurate sound from the moment you power on. The surrounding cloth is treated for resilience, supporting the cone's excursion so bass and highs land with rhythm rather than resistance.

• Weatherproof design protects against moisture, salt, and spray while maintaining sound quality
• Rigorous basket construction supplies a solid platform for clean, precise output
• Wide-dispersion tweeter geometry helps you hear clearly from more seating positions

Sound, light, and life on deck

These speakers pair practical performance with ambient RGB lighting. The illumination option lets you set the mood after sunset, potentially helping passengers locate speakers and creating a memorable onboard atmosphere.

• RGB illumination offers multiple color choices to match your boat’s lighting scheme
• Full-range, 2-way design delivers a balanced mix of mids, highs, and controlled low-end
