It is intended for boats and powersports systems that need dedicated low-frequency output while preserving available storage or cockpit space. A mounting baffle is required to separate the front and rear sound waves and help prevent acoustic cancellation.\u003c\/p\u003e\u003cp\u003eThis dual-voice-coil model is rated for 400 watts RMS and 1,600 watts peak power handling. Its 20-750 Hz frequency response and 90 dB sensitivity support a strong low-frequency foundation for a marine audio system. The 4-ohm DVC design uses Rockford Fosgate's VersaSwitch to select either a 2-ohm or 8-ohm final load without rewiring the voice coils.\u003c\/p\u003e\u003cp\u003eIntegrated Color Optix RGB LED lighting adds illumination around the subwoofer for coordinated marine-system styling. The lighting can connect to a separately sold Rockford Fosgate PMX-RGB Color Optix controller for color-pattern control through the RF Connect app. The subwoofer also includes a Color Optix harness and uses integrated connector provisions to simplify signal and lighting connections.\u003c\/p\u003e\u003cp\u003eThe M2D4-12I is built for exposed marine environments with an Element Ready design and IP67 certification. Its white finish can be tailored with the included stainless-steel grille or white Sport grille insert. This makes it suitable for installations where appearance, water resistance, and UV exposure are practical considerations.\u003c\/p\u003e\u003cp\u003eFor reliable operation in an infinite-baffle application, Rockford Fosgate specifies an infrasonic filter at or above the subwoofer's free-air resonance frequency. An active 80-100 Hz low-pass crossover at 12 dB per octave is also recommended for subwoofer use. Pair it with an amplifier that is stable at the selected 2-ohm or 8-ohm VersaSwitch setting and sized appropriately for its RMS rating.\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 mounting baffle instead of a dedicated enclosure.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVersaSwitch Impedance:\u003c\/strong\u003e Selects a 2-ohm or 8-ohm load without voice-coil rewiring.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e400-Watt RMS Handling:\u003c\/strong\u003e Supports amplifier matching for substantial marine bass output.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eColor Optix RGB Lighting:\u003c\/strong\u003e Adds integrated multicolor lighting with optional controller-based customization.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIP67 Element Ready Construction:\u003c\/strong\u003e Built for marine exposure to water, dust, and UV conditions.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInterchangeable Grilles:\u003c\/strong\u003e Includes stainless-steel and white Sport grille styling options.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eDesign \u0026amp; Installation\u003c\/h3\u003e\u003cp\u003eThe M2D4-12I combines a white marine-ready frame and trim system with an interchangeable two-piece grille arrangement. Included stainless-steel mounting screws, a stainless-steel grille, and a white Sport grille support a finished appearance suited to exposed boat installations. The integrated Color Optix harness and connector-based wiring provisions help keep the lighting setup organized.\u003c\/p\u003e\u003cp\u003ePlan for a 10.9-inch cutout, 5.24-inch mounting depth, and 13.87-inch overall diameter before installation. Mount the subwoofer on a properly sized baffle that isolates the front and rear wave paths, then set the VersaSwitch to match an amplifier rated for either 2 or 8 ohms. Use an infrasonic filter for infinite-baffle operation, set a suitable low-pass crossover, and use the optional PMX-RGB controller when app-based Color Optix control is desired.\u003c\/p\u003e","brand":"Rockford Fosgate","offers":[{"title":"Default Title","offer_id":45633944944710,"sku":"M2D4-12I","price":599.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0048\/4163\/5910\/files\/71SFfSbR0zL.jpg?v=1784426794","url":"https:\/\/audiowatt.store\/products\/rockford-fosgate-m2d4-12i-12-marine-infinite-baffle-subwoofer","provider":"Audio Watt Store","version":"1.0","type":"link"}
