The Rockford Fosgate M1D2-12B is designed to thrive where other subwoofers struggle. Tested to ASTM B117 salt fog and ASTM G154 UV standards, it is made to handle harsh marine environments with ease. Sun, salt, and moisture are no match for its rugged construction, so you can count on consistent bass performance whether you are out on the water or running an open-air setup.
This subwoofer makes system matching simple and efficient. With its selectable dual impedance system, you can switch between 1 ohm and 4 ohms using the built-in configuration for the dual 2 ohm voice coils. That means less hassle and more compatibility with different amplifiers, all while maintaining a solid 300W RMS and 1200W peak output. It also supports sealed, ported, and infinite-baffle setups, giving you the freedom to tune your system exactly the way you want.


Performance and style come together perfectly with the M1D2-12B. The integrated RGB lighting system lets you customize your look with vibrant colors like aqua, pink, yellow, or white, while the waterproof Deutsch connector keeps everything sealed and reliable. Behind the scenes, VAST technology increases cone efficiency for stronger bass, and Klippel Verified engineering keeps distortion low and sound accuracy on point. Add in corrosion-resistant stainless steel hardware and flexible wiring options, and you get a subwoofer that delivers powerful, clean bass while looking just as impressive as it sounds.
