The Rockford Fosgate RM110D4 is a 10-inch Prime R1 subwoofer engineered specifically for the demanding environments of marine watercraft and powersports. This unit features a color-molded grille and 100% UV stable ASA injection molded plastic parts, ensuring durability against the elements. Its construction includes a UV and Salt-Fog Resistant Santoprene surround and a moisture, tear, and fatigue-resistant Aramid fiber spider, all contributing to its True Marine Grade compliance. The cone body is made from injection-molded mineral-filled polypropylene with UV inhibitors, further enhancing its longevity in harsh conditions. The RM110D4 also boasts proprietary corrosion-resistant spring-loaded push terminals and an ultra-flexible, fully insulated silicone lead wire. Its specifications include a 2-inch anodized aluminum voice coil former for superior heat dissipation and a FlexFit 2 basket with slot-mounted frame pattern for adjustable mounting positions. This model offers a power handling of 200W RMS and 400W Max, with a nominal impedance of Dual 4-Ohm.
