Overview
The RFW1R is a competition-grade, heavy-duty 1/0 AWG primary power wire engineered to feed massive amounts of current to high-wattage amplifier setups. By utilizing a high strand count of 100% pure oxygen-free copper instead of budget copper-clad aluminium (CCA), it maintains low electrical resistance, zero voltage drops, and optimal thermal efficiency under intense electrical loads. Its marine certification and high-flex frost jacket make it an industry choice for premium car audio builds, marine sound systems, and commercial high-current power distribution.
Key features
100% Pure Copper: Made of Pure Crystal-Oxygen Free Copper (PC-OFC) to provide maximum electrical conductivity and eliminate high-amperage power loss. High Strand Count: Features an ultra-dense 4,704-strand design bundled into a true 1/0 AWG core (53.5mm² wire cross-section).True-Spec AWG Compliance: Meets or exceeds full American Wire Gauge requirements and CTA-2015 industry standards, ensuring honest copper thickness without oversized plastic fillers. Frosted Outer Jacket: The vibrant red insulation delivers an incredibly pliable, flexible texture that simplifies pulling heavy power cable through tight vehicle grommets and interior bends. Marine Certified: Carries a BC-5W2 marine-grade specification, shielding the copper from premature oxidation and dry rot in high-humidity setups.
