Purpose-built for Marine or Motorsport

The M1D4-8 Color Optix™ 8” DVC 4-Ohm subwoofers deliver loud, clear, accurate bass, and light the way for your journey! The subwoofers connect with the Rockford Fosgate Color Optix™ Controller and RF Connect App, allowing you to customize your own color patterns. The Element Ready™ design and IPX6 certification makes them truly purpose-built for marine or motorsport applications where protection from damaging UV rays and water spray is essential.

Light Up the Night

The sub also features Rockford Fosgate's Color Optix™ RGB LED lighting system to give you bright, colorful lighting that accents your boat's interior. The lighting can be programmed for a variety of special lighting effects via the PMX-RGB lighting controller (required, sold separately) or through a smartphone app.

Switchable Impedance

The 2-position VersaSwitch™ lets you set up the sub for 2-ohm or 8-ohm impedance with a simple flip of the switch. Deutsch™ and Amphenol™ waterproof wiring connectors will stand up to the elements, whether you're on open water or tied up at the marina. This Element Ready™ sub won't miss a beat — and neither will you.
