The M1D4-12B Color Optix™ 12” 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.

The M1 series of Element Ready™ subwoofers are designed to pair with the Rockford Fosgate Color Optix™ Controller and RF Connect App through its Deutsch™ and Amphenol™ connectors integrated into the basket. This combined with their IP67 certification make these speakers Element Ready™ and truly purpose built for marine applications. To compliment the plug and play connectivity and streamline installation, M1 subwoofers are equipped with a VersaSwitch™ to make changing impedance between 2 and 8 ohms as easy as flipping a switch.
