Rockford Fosgate RFW1B-51 51-Ft 1/0 AWG Power/Ground Wire

The Rockford Fosgate RFW1B-51 is a 51-foot bulk spool of 1/0 AWG power and ground cable for car-audio electrical installations. It provides installers and system builders with substantial cable length for custom power, ground, or battery-upgrade routing. Its frosted black finish offers a coordinated appearance for installations where black cable is preferred.

This cable is intended for systems that need a large-gauge electrical connection between components such as the battery, chassis ground, distribution hardware, and amplifiers. The bulk-spool format is useful when a project requires custom-length runs rather than pre-cut cable. Select the required length for each run before cutting and terminating the wire.

Rather than affecting the audio signal directly, the RFW1B-51 supports the electrical foundation of an amplified sound system. Its Pure Crystal-Oxygen Free Copper conductor is designed for power and ground cable duty. The 1/0 AWG conductor uses 4,704 strands and a flexible outer jacket to make routing more manageable.

Rockford Fosgate specifies this cable as full AWG spec, meeting or exceeding American Wire Gauge requirements and conforming to the CEA-2015 industry standard. It is also listed to the BC-5W2 marine specification for boats and non-commercial marine vessels. These characteristics make it appropriate for vehicle and qualifying marine electrical-cable applications.

The RFW1B-51 can serve as a core material for a custom amplifier wiring plan or a larger electrical-system upgrade. Pair it with appropriately sized terminals, fusing, distribution components, and protective loom selected for the specific installation. Proper routing, secure connections, and correctly rated circuit protection remain essential for a safe installation.

Key Features

• 1/0 AWG Size: Large-gauge cable for power and ground applications.
• PC-OFC Conductor: Uses Pure Crystal-Oxygen Free Copper construction.
• 4,704 Strands: Multi-strand conductor supports cable flexibility.
• Frosted Black Jacket: Flexible outer jacket with a black finish.
• Standards Compliance: Meets AWG requirements and CEA-2015 standards.

Design & Installation

The RFW1B-51 uses a black frosted outer jacket over a multi-strand Pure Crystal-Oxygen Free Copper conductor. Rockford Fosgate identifies the cable as 1/0 AWG, or 53.5 mm², with 4,704 strands. The cable is specified with an approximately 16.0 mm outside diameter.

Measure the intended power and ground routes before cutting cable from the spool, then choose terminals and protection components that match the 1/0 AWG wire size. Use properly rated fusing near the power source as required by the installed equipment and vehicle. This cable is suited to custom car-audio wiring projects and is also specified for boats and non-commercial marine vessels under BC-5W2.
