Its dual 4-ohm voice coils and built-in VersaSwitch provide a choice of 2-ohm or 8-ohm final impedance. This makes it a flexible option when matching a subwoofer to a compatible amplifier and system layout.\u003c\/p\u003e\u003cp\u003eWith 300 watts RMS and 1,200 watts peak power handling, the M1D4-10B is intended for systems that need substantial bass reinforcement without moving to a larger 12-inch model. Its rated frequency response extends from 20 Hz to 750 Hz, supporting dedicated low-bass duty when used with appropriate crossover settings. A 91.5 dB sensitivity rating helps it produce useful output from moderate amplifier power.\u003c\/p\u003e\u003cp\u003eThe M1D4-10B uses an injection-molded mineral-filled polypropylene cone with UV inhibitors and a Santoprene VAST surround. The vertical attach surround technique increases effective radiating cone area while maintaining a compact 10-inch format. A 2-inch high-temperature Kapton voice-coil former, linear synthetic-fiber spiders, and insulated silicone tinsel leads support its marine-focused construction.\u003c\/p\u003e\u003cp\u003eColor Optix RGB lighting is integrated behind the black grille for coordinated illumination in compatible Rockford Fosgate systems. The subwoofer connects to a separately sold PMX-RGB Color Optix controller and can be adjusted through the RF Connect app. Integrated Deutsch and Amphenol connections help simplify RGB and speaker wiring in a marine installation.\u003c\/p\u003e\u003cp\u003eBuilt for exposed installations, the M1D4-10B carries an IP67 certification and uses UV-stable ASA plastic for its frame and grille. Its vented motor includes a water-repelling nano-coated mesh screen, while marine-grade brass terminals receive zinc-nickel plating. It can be used in sealed or vented enclosures sized to the published recommendations.\u003c\/p\u003e\u003ch3\u003eKey Features\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003e300-Watt RMS Handling:\u003c\/strong\u003e Supports substantial bass output with a properly matched amplifier.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVersaSwitch Impedance:\u003c\/strong\u003e Select 2-ohm or 8-ohm operation without rewiring voice coils.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eColor Optix RGB Lighting:\u003c\/strong\u003e Adds customizable illumination through the optional compatible controller.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIP67 Element Ready Design:\u003c\/strong\u003e Built for marine and powersports exposure to water, salt, and UV.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e10-Inch Dual Voice Coil:\u003c\/strong\u003e Provides system-wiring flexibility in a compact subwoofer format.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVAST Santoprene Surround:\u003c\/strong\u003e Increases effective cone area while supporting controlled excursion.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eDesign \u0026amp; Installation\u003c\/h3\u003e\u003cp\u003eThe M1D4-10B combines a UV-inhibited mineral-filled polypropylene cone, co-molded Santoprene surround, UV-stable ASA frame and grille, and a vented motor with nano-coated mesh protection. Its 2-inch Kapton voice coil former and linear synthetic-fiber spiders are intended to support reliable operation in marine and motorsports environments.

Set the VersaSwitch for the 2-ohm or 8-ohm load appropriate for the amplifier, then follow the amplifier manufacturer's impedance guidance. RGB lighting requires the separately sold PMX-RGB Color Optix controller and compatible wiring.\u003c\/p\u003e","brand":"Rockford Fosgate","offers":[{"title":"Default Title","offer_id":45633767899206,"sku":"M1D4-10B","price":259.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0048\/4163\/5910\/files\/718VfBP1ZeL.jpg?v=1784424950","url":"https:\/\/audiowatt.store\/products\/rockford-fosgate-m1d4-10b-10-marine-led-subwoofer","provider":"Audio Watt Store","version":"1.0","type":"link"}
