Rockford Fosgate M2D4-12SB 12" Black Color Optix Sealed enclosure Dual 4 ohm marine subwoofer

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.

Switchable impedance

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.

Strong performer

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.
