M2D4/D2-10S

The Rockford Fosgate M2D4/D2-10S is a high-performance 25 cm (10") marine subwoofer from the M2 series, designed specifically for use on boats and in demanding environments. With 400 watts RMS and 1,600 watts of peak power, it delivers powerful and precise bass reproduction. Thanks to its Element Ready™ construction, durable materials, and water-resistant components, it is ideally suited for marine applications.

The built-in Color Optix™ RGB LED lighting allows for custom color configurations and can be controlled via a compatible Rockford Fosgate Color Optix™ controller or the RF Connect app. Built-in Deutsch™ and Amphenol™ connectors simplify installation.

The innovative VersaSwitch™ system allows you to switch the impedance without the need for time-consuming rewiring. The D4 model offers 2 or 8 ohms, while the D2 model can be switched between 1 and 4 ohms.

The subwoofer was specifically designed for compact, sealed enclosures. Its mineral-filled polypropylene cone, UV-resistant foam surround, and VAST technology—which increases the effective cone area by up to 25%—ensure reliable bass reproduction. Two different grille designs offer additional styling options.
