The M2D4-12S Color Optix™ 12” DVC 4-Ohm sealed enclosure subwoofers deliver loud, clear, accurate bass, and light the way for your journey! M2 provides a customized look by using either the stainless-steel grille or the white “sport” grille inserts. 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. This subwoofer is optimized for small sealed enclosures where space is at a premium.

The M2 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, M2 subwoofers are equipped with a VersaSwitch™ to make changing impedance between 2 and 8 ohms as easy as flipping a switch. This subwoofer is designed to perform in small sealed designs when there is very little space for an enclosure.
