The JL Audio M3-650X-SGMI 6.5" Marine Speaker offer the perfect balance of performance, durability, and stunning style for your boat. These premium speakers deliver dynamic sound and marine-grade construction, built specifically for harsh marine environments.
Featuring a Sport Grille with a Matte White finish and built-in LED illumination, this model provides powerful audio with stylish visual flair. Whether you're anchored in the bay or slicing across open waters, these marine speakers make every ride unforgettable.Each speaker is tested for frequency accuracy and tonal balance. This guarantees smooth output across your boat’s listening zones, delivering immersive audio whether you're idling in the marina or speeding offshore.
🌊 Weather-Resistant and Built to Last
Marine environments expose audio equipment to sun, salt, and moisture. That’s why JL Audio engineered the M3-650X-SGMI to resist these elements. The speaker features corrosion-resistant polymer baskets and UV-treated materials.
These components meet rigorous ASTM B117 (salt-fog) and ASTM D4329 (UV exposure) standards. The result is consistent performance and great appearance after years on the water.
The speaker’s hardware is all stainless steel, making it rust-proof and durable for long-term marine use.
🔉 Rich, Full-Range Sound with Balanced Output
Each speaker in this series includes a long-excursion 6.5-inch woofer and a 0.75-inch silk dome tweeter. Together, they produce clean mids, crisp highs, and tight, accurate bass.
With a power rating of 60 watts RMS and 225 watts peak, the M3-650X-SGMI delivers volume and clarity even without an external amplifier. For more punch and enhanced range, pair it with a marine amplifier.
You’ll enjoy distortion-free sound at any volume, whether docked or in motion.
🌟 Sporty Looks with Integrated Lighting
This model features JL Audio’s Sport Grille with a Matte White finish and RGB LED illumination. The built-in LEDs create ambient lighting that can match your boat’s style or mood.
Choose from multiple colors with an RGB controller (sold separately). The lights add a premium feel and extra visibility at night.
These speakers don’t just sound great—they look impressive too.

☀️ Protect Your Gear with Marine Window Tint
Electronics and speakers degrade faster under constant UV and heat exposure. Installing marine window tint helps block harmful rays, reduce glare, and keep interiors cooler.
This extends the life of your marine electronics while improving comfort and visibility. For the best results, we recommend Window Tint Delaware.
