It is designed to mount in a properly isolated baffle or panel, using the available airspace behind the mounting surface rather than a separate box. This approach helps add low-frequency output while preserving usable onboard space.\u003c\/p\u003e\u003cp\u003eWith a 400-watt RMS power rating and dual voice coils, the M2D2-12I is intended for amplified marine systems that need substantial bass support. Its 20 Hz to 750 Hz published frequency response and 15 mm Xmax support low-frequency reproduction in an open-baffle application. An active low-pass crossover and an infrasonic filter are recommended for dependable system operation.\u003c\/p\u003e\u003cp\u003eThe integrated VersaSwitch simplifies impedance setup by allowing the subwoofer to be switched to a 1-ohm or 4-ohm nominal load. This gives installers flexibility when matching the subwoofer to a compatible marine amplifier without conventional series or parallel voice-coil wiring. The switchable arrangement can also help when planning systems with multiple subwoofers.\u003c\/p\u003e\u003cp\u003eColor Optix RGB LED lighting is integrated into the design for illuminated marine installations. When paired with the separately sold Rockford Fosgate PMX-RGB Color Optix controller and RF Connect app, the lighting can be customized within the larger Color Optix ecosystem. Integrated marine-style connector provisions help support a cleaner installation.\u003c\/p\u003e\u003cp\u003eThe M2D2-12I is part of Rockford Fosgate's Element Ready marine lineup and carries an IP67 rating for water and dust protection. Its UV-stable ASA frame and grille design, weather-conscious materials, and interchangeable grille styling make it appropriate for exposed marine mounting locations. It is sold individually and includes sport and stainless-steel grille options for coordinating with a boat's finish.\u003c\/p\u003e\u003ch3\u003eKey Features\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eInfinite-Baffle Design:\u003c\/strong\u003e Optimized for installations that use a properly isolated mounting baffle instead of a separate enclosure.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e400-Watt RMS Handling:\u003c\/strong\u003e Supports use with a suitably matched marine amplifier for strong bass output.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVersaSwitch Impedance:\u003c\/strong\u003e Select 1-ohm or 4-ohm nominal impedance with a built-in switch.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eColor Optix RGB Lighting:\u003c\/strong\u003e Adds integrated multicolor illumination when connected to the compatible controller.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIP67 Element Ready Construction:\u003c\/strong\u003e Helps protect the subwoofer in demanding marine environments.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInterchangeable Grille Inserts:\u003c\/strong\u003e Includes sport and stainless-steel styling options for a coordinated appearance.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eDesign \u0026amp; Installation\u003c\/h3\u003e\u003cp\u003eThe M2D2-12I uses an injection-molded polypropylene cone, rubber surround, high-temperature aluminum voice coil, and double-stacked magnet structure. Its white UV-stable ASA frame and grille system are designed for marine exposure, while the removable two-piece grille accepts either sport or stainless-steel inserts. The subwoofer includes a grille\/trim ring assembly and uses stainless mounting hardware.\u003c\/p\u003e\u003cp\u003eInstall this model in an infinite-baffle location with a mounting baffle that separates the front and rear wave paths to prevent acoustic cancellation. The manufacturer specifies an 11-inch cutout diameter and 5.13-inch mounting depth; verify panel clearance before cutting. Use a compatible amplifier, set the VersaSwitch for the intended impedance load, and use an active 80-100 Hz low-pass crossover plus an infrasonic filter at or above the subwoofer's resonant frequency for infinite-baffle use.\u003c\/p\u003e","brand":"Rockford Fosgate","offers":[{"title":"Default Title","offer_id":45633869480006,"sku":"M2D2-12I","price":599.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0048\/4163\/5910\/files\/71XrpEGc0GL.jpg?v=1784426092","url":"https:\/\/audiowatt.store\/products\/rockford-fosgate-m2d2-12i-12-marine-infinite-baffle-subwoofer","provider":"Audio Watt Store","version":"1.0","type":"link"}
