The M1 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.
