M2D4/D2-10I

The Rockford Fosgate M2D4/D2-10I from the M2 Color Optix™ series is a powerful 25 cm (10") marine subwoofer designed specifically for use on boats and in demanding outdoor environments. With 400 watts RMS, a rugged, water-resistant design, and built-in RGB LED lighting, it delivers powerful bass reproduction and a customizable look.

Thanks to Element Ready™ technology, the subwoofer is highly resistant to moisture, UV radiation, and harsh environmental conditions. The mineral-filled polypropylene cone, UV-resistant foam surround, and high-quality marine-grade connectors ensure high power handling and a long service life.

The subwoofer was specifically designed for infinite-baffle or free-air installations and does not require a traditional enclosed subwoofer enclosure. It requires a suitable mounting surface that acoustically separates the front and back.

The built-in VersaSwitch™ impedance switch allows you to change the total impedance without the need for extensive rewiring. The built-in Color Optix™ RGB lighting can be customized using an optional Rockford Fosgate Color Optix™ controller and the RF Connect app.
