Product details
Black Prime marine coaxials
Open boats and side-by-sides need speakers that survive sun and spray, not just look the part. The RM1652B is Rockford Fosgate’s black Prime Marine 6.5-inch coaxial: a mineral-filled polypropylene cone body with UV inhibitors, a Santoprene surround rated for UV and salt fog, and 100% UV-stable ASA injection-molded plastic parts. A moisture-, tear-, and fatigue-resistant Aramid fiber spider backs the cone.

Tweeter in the grille, easy terminals
A 1-inch LCP volcano dome tweeter is integrated into the grille so the midrange cone stays clean. Corrosion-resistant quick-disconnect speaker terminals speed the install and resist oxidation. Ultra-flexible fully insulated silicone lead wire handles vibration. A 6 dB/octave high-pass crossover protects the tweeter. Frequency response is 49 Hz–20 kHz with 89 dB sensitivity at 1 W/1 m.

Fitment basics
Mounting depth is 2.5 inches (63 mm). Impedance is 4 ohms. Stainless-steel mounting hardware and black grilles are included. A white version is available separately when you need a lighter console match. These are the same RM1652B drivers used in Rockford’s GENERAL and RANGER Stage 2 kits when you buy speakers on their own. True Marine Grade compliance is the point of this Prime pair—use them where UV, spray, and vibration would finish off ordinary car speakers quickly.
