Rockford Fosgate M1D2-10 Color Optix is a 10-inch dual voice coil (DVC) marine subwoofer built for harsh marine conditions, featuring IP67-rated protection and integrated RGB/LED lighting compatibility. It offers adjustable impedance via an onboard switch (1 ohm to 4 ohm) and is designed to plug into the Color Optix ecosystem, but you will need the compatible Color Optix controller/app setup (sold separately) to use the lighting effects.
The Rockville MS12LB is a 12-inch marine free-air subwoofer aimed at boat audio setups that want louder, cleaner low-end without needing an enclosure. It’s built with a waterproof polypropylene cone, rubber surround, and a molded ABS basket, plus a 2.0-inch dual 4-ohm voice coil and front LEDs. Reviews point to strong sound for the money, though buyer feedback is mixed on consistency (including at least one faulty-driver/LED wiring complaint).
Rockford Fosgate’s M1D4-10 Color Optix is a 10-inch DVC 4-ohm marine subwoofer designed for boats and water-spray environments. It combines IP67-rated durability with multicolor, wide-angle LED lighting, plus app-based lighting control when paired with the Color Optix controller (sold separately). The main catch for buyers is planning the Color Optix accessory kit, since the lighting ecosystem is not plug-and-play without the right controller and cables.

It targets controlled low-end (rated 30–500 Hz) and is designed for outdoor, salt/fog, and UV exposure, making it a practical choice for boats or other weather-exposed audio setups. Main caveat: you will likely need to plan around grille and controller add-ons sold separately for the full look and lighting features.
The Rockford Fosgate M2D4-10I is a 10-inch infinite baffle marine subwoofer designed for loud, clean low-end in boats or other marine builds, with IP67 water and UV protection.

The main buying caveat is enclosure and wiring fit, including potential differences versus older subwoofer models.
