JL Audio M3-10IB-S-Gm-4 10" 175W RMS Infinite-Baffle Marine Subwoofer, Gray Sport Grille (010-03071-00)

Add deeper, more authoritative bass to your boat with the JL Audio M3-10IB-S-Gm-4 M3 Series 10" marine subwoofer. Designed primarily for infinite-baffle installation, it can be mounted into an appropriate bulkhead without requiring a conventional dedicated subwoofer box. Its gray sport grille provides a finished marine appearance.

The 4-ohm driver handles 175 watts RMS and combines a UV-protected polypropylene cone, resilient rubber surround and corrosion-resistant construction for low-frequency performance in exposed boating environments.
