Big bass and colorful lighting
Rockford Fosgate's M2D4-12 marine subwoofer brings powerful bass to your boat, along with selectable RGB LED lighting for great looks to match its great sound. This flagship sub is designed for small, sealed enclosures, so you can expect strong, accurate low-frequency punch.
Made for life on the water
This M2 Series M2D4-12 12" sub features a rugged, removable grille that looks great and stands up to blistering sunlight and damaging moisture. Stainless-steel mesh or sport-style inserts are included, so you can pick the look that best suits your boat. Underneath the UV-stable ASA plastic frame, you'll find a injection-molded mineral-filled polypropylene cone that's treated with UV inhibitors, plus a moisture- and tear-resistant synthetic fiber blend spider.
The 2-position VersaSwitch™ lets you set up the sub for 2-ohm or 8-ohm impedance with a simple flip of the switch. Deutsch™ and Amphenol™ waterproof wiring connectors will stand up to the elements, whether you're on open water or tied up at the marina. This Element Ready™ sub won't miss a beat — and neither will you.
Light up the night
The sub also features Rockford Fosgate's Color Optix™ RGB LED lighting system to give you bright, colorful lighting that accents your boat's interior. The lighting can be programmed for a variety of special lighting effects via the PMX-RGB lighting controller (required, sold separately) or through a smartphone app.
This bass powerhouse handles up to 400 watts RMS, so choose a strong marine amp for top performance. Powerful enough for bass-heavy music, the M2D4-12 is a great choice for anyone who's building a serious marine audio system and wants to make a colorful impression.

More details on the Rockford Fosgate M2D4-12S
Marine Tested: Rockford Fosgate uses industry standard tests (ASTM B117 salt/fog and ASTM G154 UV) to ensure the M2 series subwoofers are durable in the difficult marine environment.
Impedance Switch: A switch on the input terminal allows you to easily change the subwoofer's impedance between 2Ω and 8Ω, internally changing between wiring the dual 4Ω voice coils in parallel and in series. (The connected amplifier should be off when changing the impedance.) The power handling is the same for either setting; 400 watts RMS/1600 watts peak.
LEDs: There are red, green, and blue LEDs on the back of the grille to create a glow on the woofer cone. The LEDs can be powered individually, or in any combination you like. Depending on what combination of LED wires is connected, they light red, green, blue, yellow, pink, aqua, or white. A 12 volt power supply is needed to turn the LEDs on and a 1-amp fuse should be added in-line (fuse not included). The LEDs can also be controlled using Rockford Fosgate's LED Controller (item number 575PMXRGB, sold separately). An LED power wire harness is included with a 4-pin waterproof Deutsch DT Series connector that plugs into the subwoofer frame.
Speaker Terminals: In addition to standard male quick slide terminals, the subwoofer also has a 2-pin waterproof Deutsch terminal. A speaker wire harness with a 2-pin waterproof Deutsch DT Series connector is not included.
VAST Surround: The Vertical Attach Surround Technique (VAST) increases a speaker's effective radiating cone area without increasing the size of the basket.
Klippel Verified: The Klippel distortion analyzer, a device that uses a laser and sophisticated software to do large-scale analysis of drivers in motion, lets Rockford Fosgate optimize the speaker's motor structure, voice coil alignment, and suspension to yield the best possible performance.
Stainless Steel: The included mounting hardware is stainless steel to resist corrosion.
Enclosure: This sub is designed to be mounted in a small sealed enclosure; 0.75 ft³.
