JL Audio M6-8IB-S-GmTi-4 8" Marine Infinite-Baffle Subwoofer 200W 4Ω, 200W RMS, Single 010-03275-00 (93619)

JL Audio M6-8IB-S-GmTi-4 8" Marine Infinite-Baffle Subwoofer is a premium 8-inch marine subwoofer engineered for open-air, enclosure-free locations on today’s boats. With its Gunmetal Sport grille and Titanium insert, it delivers serious low-frequency output while matching modern OEM and custom marine interiors.

Optimized for infinite-baffle use, this M6 subwoofer is rated for 200 W RMS at a nominal 4 Ω, and is best paired with 75–200 W of clean amplifier power. Adding this driver lets your main speakers hand off deep-bass duties, so the entire marine system can play louder and stay cleaner at cruising and wakeboarding volumes.
