Its dual 2-ohm voice-coil design uses an integrated VersaSwitch to provide a 1-ohm or 4-ohm final impedance option. This helps simplify matching the subwoofer to a compatible amplifier without changing internal voice-coil wiring.\u003c\/p\u003e\u003cp\u003eRated for 300 watts RMS and 1,200 watts peak, the M1D2-12B is intended for systems that need stronger bass support than full-range marine speakers can provide alone. Its 20 Hz to 750 Hz frequency response and 92 dB sensitivity support low-end reinforcement in an appropriately configured system. Use an active low-pass crossover to direct bass frequencies to the subwoofer.\u003c\/p\u003e\u003cp\u003eColor Optix RGB lighting is integrated into the subwoofer for illuminated marine-system installations. When paired with the separately sold Rockford Fosgate PMX-RGB Color Optix controller, lighting can be controlled through the RF Connect app. The included Color Optix harness supports the lighting connection, while the subwoofer also supports fixed-color hardwiring when installed correctly.\u003c\/p\u003e\u003cp\u003eThe M1D2-12B is built for exposed marine environments with an Element Ready design and IP67 certification. Its UV-stable polypropylene cone, Santoprene VAST surround, UV-stable ASA frame and grille, and marine-grade terminals are selected for marine use. A vented motor with a water-repelling nano-coated mesh screen supports the weather-resistant design.\u003c\/p\u003e\u003cp\u003eFor system upgrades, this subwoofer can be installed in a sealed, vented, or infinite-baffle-style application when the enclosure and filtering are designed for the installation. The 10.85-inch cutout diameter and 6.65-inch mounting depth should be checked before cutting a mounting surface. It is sold individually with a fixed Sport grille, Color Optix harness, mounting hardware, and installation documentation.\u003c\/p\u003e\u003ch3\u003eKey Features\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eVersaSwitch Impedance:\u003c\/strong\u003e Selects a 1-ohm or 4-ohm final load without separate series or parallel voice-coil wiring.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e300-Watt RMS Handling:\u003c\/strong\u003e Supports use with a properly matched marine amplifier for sustained bass output.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eColor Optix RGB Lighting:\u003c\/strong\u003e Adds multicolor illumination and works with the optional PMX-RGB controller and RF Connect app.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIP67 Element Ready Design:\u003c\/strong\u003e Built for marine environments where UV exposure and water resistance matter.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e12-Inch DVC Platform:\u003c\/strong\u003e Uses dual 2-ohm voice coils and a 2-inch high-temperature Kapton voice-coil former.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMarine-Grade Construction:\u003c\/strong\u003e Combines a UV-stable cone, Santoprene surround, ASA frame, and corrosion-resistant terminals.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eDesign \u0026amp; Installation\u003c\/h3\u003e\u003cp\u003eThe M1D2-12B uses an injection-molded mineral-filled polypropylene cone with UV inhibitors, a co-molded Santoprene VAST surround, and linear synthetic-fiber-blend spiders. Its black ASA frame and fixed Sport grille are UV stable, while zinc-nickel-plated marine-grade brass terminals and insulated silicone tinsel leads support marine-system durability. The vented motor includes a water-repelling nano-coated mesh screen, and the integrated connectors are designed to streamline audio and lighting connections.\u003c\/p\u003e\u003cp\u003eVerify the 10.85-inch cutout and 6.65-inch mounting depth before installation. Match the selected 1-ohm or 4-ohm VersaSwitch setting to an amplifier rated for that load, and use an active 80-100 Hz low-pass crossover for subwoofer duty. For RGB control, add the separately sold PMX-RGB controller; when hardwiring lighting, use a fused 12-volt source, a minimum 20 AWG wire, and do not connect the lighting directly to 24-volt electrical systems.\u003c\/p\u003e","brand":"Rockford Fosgate","offers":[{"title":"Default Title","offer_id":45633739522118,"sku":"M1D2-12B","price":319.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0048\/4163\/5910\/files\/71FXv3RgX8L.jpg?v=1784424692","url":"https:\/\/audiowatt.store\/products\/rockford-fosgate-m1d2-12b-12-rgb-marine-subwoofer","provider":"Audio Watt Store","version":"1.0","type":"link"}
