Built for the Open Water

The Rockford Fosgate M2D4-10I-G2 is designed to thrive in harsh marine environments. Think salt, sun, water, and whatever else Mother Nature tosses your way—this sub takes it all. It’s part of Rockford’s Element Ready™ line, so you know it’s sealed up tight against corrosion, UV rays, and moisture. Even the terminals are gold-plated marine-grade brass for long-lasting, corrosion-resistant performance.

Infinite Baffle? No Problem

What makes this sub stand out is its optimization for infinite baffle setups. No box needed here. Just mount it to a solid baffle surface, and you’re good to go. It's engineered to handle the airspace of your boat without compromising bass performance. It even comes with a vented T-yoke and redesigned motor assembly for smooth, thunderous output that doesn't bottom out.

Light It Up with Color Optix

Here’s where things get flashy—literally. With Rockford’s Color Optix™ system (PMX-RGB sold separately), you can control brilliant, wide-angle RGB lighting via the RF Connect™ App. Whether you’re going for subtle glow or party-mode pulsing, this subwoofer adds major vibe to your setup.

Customize Your Style

Want to switch up the look? You’ve got options. The M2D4-10I-G2 comes with both a sport grille insert and a stainless steel grille insert, so you can match your setup to your boat’s aesthetic. And with interchangeable parts, you can keep things fresh whenever you feel like a change.

VersaSwitch Makes Wiring Easy

Let’s face it—marine wiring can get messy. But Rockford simplifies it with its VersaSwitch™. You can switch between 2-ohm and 8-ohm configurations without digging into extra wires. Just flip a switch, and you’re done. This kind of flexibility makes it a breeze to match the sub to your system.

Built Like a Tank, Sounds Like a Dream

Everything from the mineral-filled polypropylene cone to the UV-stable frame is engineered for long-term use and crystal-clear performance. The VAST surround technique increases the cone area by up to 25%, giving you deeper bass and smoother mids. It’s even Klippel Verified, meaning it’s passed the toughest audio testing standards out there.

Marine-Grade Connections You Can Count On

The sub features integrated Deutsch™ and Amphenol™ connectors, giving you plug-and-play convenience with superior water resistance. These molded-in-frame connections aren’t just easy—they’re reliable, keeping your system performing even when the water gets rough.

Whether you’re cruising under the sun or docked at sunset, the Rockford Fosgate M2D4-10I-G2 brings the bass and the vibes. With rugged engineering, flexible install options, and customizable lighting, it’s the ultimate subwoofer for serious marine sound systems.

Sealed Enclosure Notice
Do not use this woofer in a sealed enclosure.
This model is specifically designed for vented applications listed above.
If you're looking for a sealed enclosure setup, please choose a different woofer better suited for that design.

Vented Enclosure Notice
Do not use this woofer in a vented enclosure.
It’s tuned for optimal performance in the sealed enclosure(s) outlined above.
If a vented setup is required, we recommend selecting a woofer built for that application.

Infinite Baffle Setup Guidelines
An Infinite Baffle (IB) setup requires that the air volume behind the woofer is much larger than the woofer’s own suspension compliance (Vas).
To ensure reliable performance in IB systems, an infrasonic filter is mandatory.

Installation Notes:

• Use a 3/4" (18mm) thick MDF baffle board.
• Any air leaks in the baffle or cavity can severely impact performance.
• Make sure the entire cavity and baffle board are completely sealed for best results.
• Again, don’t skip the infrasonic filter—it’s crucial for proper operation in this setup.
