Product details
Black Element Ready 6.5s for open-air machines
Boat consoles and UTV dashes fade ordinary speakers fast. The M0-65B is Rockford Fosgate’s black M0-series 6.5-inch coaxial pair, purpose-built so water, salt, dust, and UV do not end the season early. A mineral-filled polypropylene cone is co-molded to a Santoprene surround that uses VAST vertical-attach technique to grow effective cone area by up to about 25%. The UV-stable ASA plastic frame and grille keep their color in direct sun.

Sealed crossover and marine terminals
A fully sealed integrated concealed crossover (ICC) network keeps the high-pass filter out of the spray path. Zinc nickel-plated marine-grade brass terminals resist corrosion, and linear synthetic-fiber-blend spiders support the cone through long travel days. Frequency response is 40 Hz–25 kHz; sensitivity is 90.5 dB at 1 W/1 m. The grille-integrated 0.5-inch LCP balanced-dome tweeter crosses at 6 dB/octave on a sealed motor with a 1-inch high-temp Kapton voice-coil former.

Fitment basics
Mounting depth is 2.52 inches (63.9 mm). Black grilles and stainless-steel mounting hardware ship in the pair. Shipping weight is about 1.93 pounds. Match amplifier power to the 65 W RMS rating and use marine-grade speaker wire in wet installs. This M0 model does not include Color Optix RGB lighting.
