series of Element Ready™ subwoofers are designed to pair with the Rockford
Fosgate Color Optix™ Controller and RF Connect App through its Deutsch™ and
Amphenol™ connectors integrated into the basket. This combined with their IP67
certification make these speakers Element Ready™ and truly purpose built for
marine applications. To compliment the plug and play connectivity and
streamline installation, M1 subwoofers are equipped with a VersaSwitch™ to make
changing impedance between 2 and 8 ohms as easy as flipping a switch.
