Rockford Fosgate M2D2-10SB-G2 10" Marine Subwoofer

The Rockford Fosgate M2D2-10SB-G2 is a 10-inch marine subwoofer designed for compact sealed-enclosure installations. It uses dual 2-ohm voice coils with a built-in VersaSwitch that selects a 1-ohm or 4-ohm final impedance. This makes it a flexible choice for marine and motorsports systems that need substantial low-frequency output without requiring a large enclosure.

Rated for 400 watts RMS and 1,600 watts peak, this M2 Series Gen-2 subwoofer is intended for use with an appropriately matched external amplifier. Its 22 Hz to 250 Hz frequency response and 13 mm Xmax support bass reproduction suited to boat, UTV, and outdoor audio systems. The 83 dB sensitivity specification and sealed-box design favor controlled bass in properly built enclosures.

The M2D2-10SB-G2 is optimized for sealed enclosures ranging from 0.5 to 1.25 cubic feet. This range helps installers fit the subwoofer into locations where enclosure volume is limited. A mounting depth of 4.70 inches and 8.98-inch cutout requirement should be checked before installation.

Rockford Fosgate builds this model for outdoor exposure with an Element Ready design, IPX6 water-intrusion rating, UV-stable materials, and corrosion-resistant marine-grade terminals. The mineral-filled polypropylene cone, polymer VAST surround, vented motor, and high-temperature 2-inch voice coil are designed for marine-duty use. Integrated Deutsch and Amphenol connections provide a plug-and-play connection option alongside 1/8-inch spade terminals.

Color Optix RGB lighting lets this subwoofer coordinate visually with compatible Rockford Fosgate marine components. Lighting control requires the optional PMX-RGB Color Optix controller and the RF Connect app. The included grille components allow a black or stainless-steel appearance, making the subwoofer suitable for systems where both audio performance and finish integration matter.

Design & Installation

This black M2 Series Gen-2 subwoofer uses a mineral-filled polypropylene cone, polymer VAST surround, UV-stable frame and grille materials, fully insulated silicone tinsel leads, and gold-plated marine-grade brass terminals. Its vented motor includes a water-repelling nano-coated mesh screen, while the basket incorporates Deutsch and Amphenol connectivity. The included stainless-steel grille, black grille spacers, mounting hardware, and RGB harness support a finished marine installation.

Install the M2D2-10SB-G2 in a sealed enclosure with 0.5 to 1.25 cubic feet of internal volume, allowing for its 0.047-cubic-foot woofer displacement. Confirm the 8.98-inch cutout and 4.70-inch mounting depth, then select the 1-ohm or 4-ohm VersaSwitch position to match an amplifier's approved load capability. For RGB lighting, connect the supplied 300 mm four-wire harness to a compatible Color Optix setup; the PMX-RGB controller is required for lighting control.
