Its dual 4-ohm voice-coil design uses an integrated VersaSwitch to select a 2-ohm or 8-ohm final impedance. The white grille, frame, and integrated RGB lighting suit installations where the subwoofer remains visible.\u003c\/p\u003e\u003cp\u003eThis model is intended for marine and motorsports systems that need bass while facing sun, moisture, vibration, and water exposure. It handles 150 watts RMS and 600 watts peak, making it appropriate for use with a properly matched external amplifier. The 8-inch format provides a compact option for smaller compartments, panels, and custom enclosures.\u003c\/p\u003e\u003cp\u003eThe M1D4-8 uses a mineral-filled polypropylene cone with a Santoprene VAST surround. Its vented motor includes a water-repelling nano-coated mesh screen, while insulated silicone tinsel leads support movement in demanding installations. The result is a purpose-built woofer intended to reproduce bass from 20 Hz to 750 Hz.\u003c\/p\u003e\u003cp\u003eColor Optix RGB illumination is integrated into the subwoofer for coordinated lighting across a compatible Rockford Fosgate marine system. The lighting connects through integrated Deutsch\/Amphenol connectors and is designed to work with a separately sold Rockford Fosgate Color Optix controller. With the compatible controller, lighting patterns can be adjusted through the RF Connect app.\u003c\/p\u003e\u003cp\u003eFor system planning, the M1D4-8 can be used in either sealed or ported enclosures. A 0.55 cubic-foot sealed enclosure is listed as the optimum sealed volume, while a 1.10 cubic-foot ported enclosure is listed as the optimum ported volume. Its selectable 2- or 8-ohm configuration gives installers flexibility when matching the subwoofer to an amplifier and additional speakers.\u003c\/p\u003e\u003ch3\u003eKey Features\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eVersaSwitch Impedance:\u003c\/strong\u003e Selects a 2-ohm or 8-ohm final load without external series or parallel coil wiring.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eColor Optix RGB Lighting:\u003c\/strong\u003e Built-in wide-angle RGB LEDs support coordinated accent lighting in compatible systems.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eElement Ready Construction:\u003c\/strong\u003e IP67-rated design helps support marine and motorsports installation environments.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e150-Watt RMS Handling:\u003c\/strong\u003e Supports amplifier matching for sustained bass performance.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMineral-Filled Polypropylene Cone:\u003c\/strong\u003e Provides a durable cone material for outdoor audio use.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIntegrated Connectors:\u003c\/strong\u003e Deutsch\/Amphenol lighting connectors simplify compatible Color Optix wiring.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eDesign \u0026amp; Installation\u003c\/h3\u003e\u003cp\u003eThe M1D4-8 combines a UV-stable ASA plastic frame and grille with a white mineral-filled polypropylene cone, Santoprene VAST surround, and marine-grade brass terminals with zinc-nickel plating.
