🌊 Built for Real Marine Environments
JL Audio builds its marine subwoofers with extreme marine conditions in mind. The M310IB-S-Gm-i-4 marine subwoofer features a sealed motor system, polymer basket, and UV-stabilized cone, all crafted to resist moisture, salt, and sun.
It meets ASTM B117 for salt-fog exposure and ASTM D4329 for UV resistance. From freshwater lakes to saltwater coasts, this subwoofer performs reliably without losing sound quality.
🔊 Infinite-Baffle Design: No Box Needed
This marine subwoofer is made for free-air mounting. That means no heavy box or enclosure is needed. You can install it directly into seat bases, consoles, or bulkheads.
With 175 watts of continuous power handling and a 4-ohm impedance, it offers strong, clean bass that complements JL Audio’s full-range speakers.
💡 LED Lighting Meets Premium Styling
The “i” in M310IBSGMI4 stands for integrated LED illumination. The RGB lighting behind the gunmetal sport grille adds a custom look to your boat’s interior or exterior.
You can wire the LEDs to respond to your boat’s lighting system or keep them on a fixed color. The lighting is waterproof and designed to withstand marine wear and tear.
⚙️ Simple Install, Big Impact
Installation is quick with the free-air design. Just mount the subwoofer in a pre-cut 10-inch opening. Connect it to a marine-grade amplifier and lighting controller (optional), and you're done.
Pair it with JL Audio marine amps for optimal performance and reliability.
