{"product_id":"100-foot-spool-4-awg-pc-ofc-power-wire","title":"100-Foot Spool 4 AWG PC-OFC Power Wire","description":"The Rockford Fosgate RFW4B is a 100-foot spool of 4 AWG negative insulated multi-strand copper cable, designed to meet or exceed American Wire Gauge (AWG) requirements for car audio power and ground applications. Constructed from 100% pure Crystal-Oxygen Free Copper (PC-OFC), this wire features 1,862 strands within its 4 AWG (21.1mm²) conductor size, ensuring superior flexibility and conductivity for clear signal transmission.\n\nThe wire is finished with a frosted black outer jacket that provides excellent abrasion resistance and a professional appearance. Its low resistance makes it ideal for long cable runs and high-powered audio systems where efficient power delivery is crucial. The bulk spool design allows for easy storage, organization, and customization of cable length during installation.\n\nThis product conforms to the CTA-2015 industry standard, guaranteeing the specified amount of copper for its gauge size, and also meets BC-5W2 marine specifications, indicating suitability for use in boats and non-commercial marine vessels. While the wire itself is included, customers should note that an appropriate fuse and fuse holder, such as the Rockford Fosgate RFFAGU, are sold separately and are required for proper circuit protection and installation.\n\nInstallation considerations include planning the cable route carefully to avoid sharp bends, moving parts, and tight openings, as the thicker gauge requires more space. Proper connections at the battery, fuse holder, and amplifier are essential to prevent voltage drop and heat buildup. Using a matching 4 AWG ground cable is also recommended for high-powered installations to maintain a secure and low-resistance connection.","brand":"Rockford Fosgate","offers":[{"title":"Default Title","offer_id":52872744862008,"sku":"RFW4B","price":499.99,"currency_code":"USD","in_stock":true}],"url":"https:\/\/store.motormia.co\/products\/100-foot-spool-4-awg-pc-ofc-power-wire","provider":"MOTORMIA","version":"1.0","type":"link"}
