JL Audio M7-12IB-S-GwGw-4 is a 12-inch, 600 W RMS marine subwoofer with a White Sport grille, 4-ohm impedance and no LED lighting. Its infinite-baffle design delivers dedicated bass without requiring a compact subwoofer box.
The large cone, long-excursion suspension and 4-inch voice coil give the M7 substantial displacement for open-air marine bass. JL Audio’s DMA-optimized motor design helps control distortion and transient response when driven by a properly matched amplifier.

Installation & System Matching
Mount in a rigid baffle that isolates the front and rear sound waves, with a sufficiently large air volume behind the driver. Infinite-baffle does not mean the rear wave can leak around the speaker into the listening area. Confirm mounting depth, cutout, fastener access and clearance before cutting.
Use a subwoofer amplifier appropriate for a single 4-ohm load and set its gain, low-pass filtering and protection to suit the 600 W RMS driver. Amplifier, power wiring and enclosure or baffle construction are not included.
What’s Included
- One JL Audio M7-12IB-S-GwGw-4 marine subwoofer
- White Sport grille
- Six stainless steel mounting screws and six washers
