The Rockford Fosgate RFW1R-51 is a 51-foot spool of 1/0 AWG power and ground cable for vehicle audio electrical installations. It provides the heavy-gauge wiring needed to connect high-current car audio equipment with appropriately sized power and ground runs. The frosted red jacket helps distinguish positive-power wiring within an installation.
This cable is intended for installers and enthusiasts building or upgrading amplified car audio systems. Its 1/0 AWG size is suited to applications that require a large-capacity main power or ground cable, subject to proper system design and fuse selection. The 51-foot spool format gives flexibility for custom-length routing and multiple installation needs.
The conductor uses Pure Crystal Oxygen-Free Copper, also identified as PC-OFC, with a 4,704-strand construction. Its listed conductor area is 53.5 mm², meeting or exceeding AWG specifications. The multi-strand design and frosted outer jacket are engineered to support flexible routing through a vehicle.
Rockford Fosgate lists this cable as compliant with the CEA-2015 industry standard and BC-5W2 requirements for use on boats and non-commercial marine vessels. These ratings make it appropriate for compatible automotive and marine electrical applications where a red 1/0 AWG cable is required. Installation should still follow applicable vehicle, marine, amplifier, and fuse-manufacturer requirements.
Use the RFW1R-51 as part of a complete power-distribution plan with correctly sized fusing, terminals, protection, and grounding hardware. It can serve as a main power or ground run when matched to the equipment's current requirements and installation length. For systems with multiple amplifiers, it can be paired with suitable distribution blocks and shorter branch cables.
Key Features
- 1/0 AWG Size: Heavy-gauge cable supports high-current power and ground wiring.
- 51-Foot Spool: Provides bulk length for custom vehicle cable runs.
- PC-OFC Conductor: Uses Pure Crystal Oxygen-Free Copper conductor material.
- 4,704-Strand Construction: Multi-strand design supports flexible cable routing.
- Frosted Red Jacket: Identifies the cable and provides a flexible outer covering.
- Marine-Grade Rating: Meets BC-5W2 requirements for applicable marine use.
Design & Installation
The RFW1R-51 combines a red frosted outer jacket with a finely stranded PC-OFC copper conductor. It is specified as 1/0 AWG with a 53.5 mm² conductor area and a 16.0 mm outside diameter. The cable is rated for temperatures up to 105°C and is designed to meet or exceed AWG specifications.
Measure the intended route before cutting cable, then select terminals, fuse holders, distribution blocks, and protective loom sized for 1/0 AWG wiring. Route the cable away from moving parts, sharp edges, heat sources, and areas where it may be pinched; protect it where it passes through metal panels. Use it for properly fused power runs or appropriately prepared ground runs according to the audio equipment and vehicle or vessel installation instructions.
