JL Audio M6-8IB-S-GwGw-i-4 8" Marine Infinite-Baffle Subwoofer is an 8-inch marine subwoofer engineered for infinite-baffle (free-air) installation on boats where a dedicated enclosure isn’t practical. Built on JL Audio’s M6 series platform, it features a Gloss White Sport grille and Transflective™ RGB LED lighting that illuminates through the cone to create a striking visual effect at night while providing serious low-frequency reinforcement.
Rated for 200 W RMS at a nominal 4 Ω, this driver is best paired with 50–200 W of clean amplifier power. JL Audio’s advanced motor design and long-excursion suspension help deliver controlled, impactful bass while taking the deep-bass workload off your full-range marine speakers so the entire system plays louder and cleaner.

Continuous power handling: 200 W RMS
Nominal impedance: 4 Ω
Optimized for large backing volume or open spaces without enclosures
Saltwater-ready materials for UV, moisture, and corrosion resistance
