{"product_id":"12-inch-marine-dual-4-ohm-subwoofer","title":"12-Inch Marine Dual 4-Ohm Subwoofer","description":"The Rockford Fosgate RM112D4B is a black 12-inch Prime R1 subwoofer engineered specifically for the demanding environments of marine watercraft and powersports. This subwoofer boasts true marine-grade compliance and is built with weatherproofing technology to withstand harsh conditions. Its construction includes a 100% UV-stable ASA injection molded plastic grille and a Santoprene surround that is resistant to UV and salt-fog.\n\nWith a power handling of 200 watts RMS and 400 watts peak, the RM112D4B is designed to deliver robust audio performance. It features dual 4-ohm voice coils, providing flexibility in system configuration. The subwoofer is suitable for various enclosure types, including sealed, vented, and infinite baffle installations. Key components like the injection-molded mineral-filled polypropylene cone body are infused with UV inhibitors to ensure longevity.\n\nInstallation and durability are further enhanced by proprietary corrosion-resistant spring-loaded push terminals and an Aramid fiber spider that resists moisture, tearing, and fatigue. The cone itself is supported by an anodized aluminum voice coil former, which improves heat dissipation, and utilizes the VAST (Vertical Attach Surround Technique) to increase effective radiating cone area. The removable trim ring\/grille adds a touch of customization.\n\nThe RM112D4B is part of Rockford Fosgate's Element Ready™ line, meaning all components are protected against dust, UV, temperature, water, corrosion, and vibration, ensuring reliable operation in extreme outdoor elements.","brand":"Rockford Fosgate","offers":[{"title":"Default Title","offer_id":52872748695864,"sku":"RM112D4B","price":149.99,"currency_code":"USD","in_stock":true}],"url":"https:\/\/store.motormia.co\/products\/12-inch-marine-dual-4-ohm-subwoofer","provider":"MOTORMIA","version":"1.0","type":"link"}
