JL Audio M6-8IB-C-GwGw-4 8" Marine Infinite-Baffle Subwoofer is a high-performance 8-inch marine subwoofer engineered for infinite-baffle (free-air) and traditional enclosure installations. Designed to operate with or without a dedicated box, this subwoofer delivers deep, controlled bass that enhances marine audio systems while fitting tight spaces where enclosure volume is limited. 

Built on JL Audio’s M6 platform with an injection-molded mica-filled polypropylene cone, synthetic rubber surround, and rugged marine-grade materials, the M6-8IB-C-GwGw-4 handles up to 200 W RMS at a nominal 4 Ω. Its Gloss White Classic grille offers a clean, premium look that integrates seamlessly with both factory and custom installations.
