Its dual 4-ohm voice-coil design and built-in VersaSwitch allow the final nominal impedance to be set to 2 or 8 ohms. It is sold individually and is intended for marine and motorsports audio installations.\u003c\/p\u003e\u003cp\u003eThis subwoofer is optimized for small sealed enclosures, making it a practical choice when installation space is limited. With 400 watts RMS power handling and a 20 Hz to 750 Hz frequency response, it is built to add substantial bass support below full-range marine speakers. The sealed-box alignment favors controlled bass response for boat, UTV, and other outdoor audio systems.\u003c\/p\u003e\u003cp\u003eColor Optix RGB LED lighting is integrated into the M2D4-12S for coordinated system illumination. A separately sold Rockford Fosgate PMX-RGB controller and the RF Connect app are required to configure lighting colors and patterns. Wide-angle LEDs help provide visible accent lighting around the subwoofer grille.\u003c\/p\u003e\u003cp\u003eThe M2D4-12S uses Element Ready construction for demanding outdoor environments. Its marine-focused design includes UV-stable ASA plastic frame and grille components, corrosion-resistant terminals, sealed Deutsch connections, and certification for marine exposure. The injection-molded mineral-filled polypropylene cone includes UV inhibitors, while the VAST surround increases effective radiating area.\u003c\/p\u003e\u003cp\u003eFor system integration, the subwoofer includes integrated Deutsch and Amphenol connectivity as well as conventional spade terminals. The VersaSwitch simplifies series or parallel voice-coil configuration without extra jumper wiring at the driver. It can be paired with a marine amplifier selected to deliver appropriate power at the chosen 2- or 8-ohm load.\u003c\/p\u003e\u003ch3\u003eKey Features\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003e400-Watt RMS Handling:\u003c\/strong\u003e Supports a properly matched marine amplifier for meaningful bass output.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVersaSwitch Impedance:\u003c\/strong\u003e Select 2- or 8-ohm nominal operation with a switch.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eColor Optix RGB Lighting:\u003c\/strong\u003e Adds configurable LED accent lighting with the optional controller.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSmall Sealed-Box Design:\u003c\/strong\u003e Optimized for installations with limited enclosure space.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eElement Ready Construction:\u003c\/strong\u003e Uses marine-oriented materials for water, salt, UV, and vibration exposure.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInterchangeable Grille System:\u003c\/strong\u003e Includes stainless-steel and sport grille styling options.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eDesign \u0026amp; Installation\u003c\/h3\u003e\u003cp\u003eThe M2D4-12S combines a UV-stable ASA plastic frame and grille structure with an injection-molded mineral-filled polypropylene cone and UV inhibitors. Gold-plated marine-grade brass terminals are used for corrosion resistance, while the integrated Deutsch DT connections use front and rear silicone seals. The two-piece grille design allows the included stainless-steel or sport grille option to be fitted to suit the installation.\u003c\/p\u003e\u003cp\u003eInstall this subwoofer in a properly built, airtight sealed enclosure with approximately 0.75 cubic foot (21 liters) of internal volume per manufacturer guidance. The mounting cutout is 11 inches and the listed mounting depth is 4.87 inches, so verify panel clearance before cutting. Use the VersaSwitch to choose the 2- or 8-ohm configuration required by the amplifier, and add the optional PMX-RGB controller when Color Optix lighting control is desired.\u003c\/p\u003e","brand":"Rockford Fosgate","offers":[{"title":"Default Title","offer_id":45633953792070,"sku":"M2D4-12S","price":599.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0048\/4163\/5910\/files\/71SFfSbR0zL_4413732d-5c8a-4332-b1a2-a14d3f79e2cd.jpg?v=1784426898","url":"https:\/\/audiowatt.store\/products\/rockford-fosgate-m2d4-12s-12-marine-rgb-subwoofer","provider":"Audio Watt Store","version":"1.0","type":"link"}
