Memphis 0FO51 1/0 AWG OFC Power Wire, 51-Ft Spool

The Memphis 0FO51 is a 51-foot spool of 0 AWG, also known as 1/0 AWG, power wire for car audio electrical installations. It provides the cable needed to route power between a vehicle battery and compatible high-current audio equipment. The orange jacket helps distinguish this run during a custom installation. It is intended for installers and enthusiasts building or upgrading an amplified audio system.

This wire uses oxygen-free copper conductors and is built to the True AWG standard stated by Memphis. A large 0 AWG conductor size is suited to applications where a substantial power cable is required. Selecting the proper wire size is an important part of controlling voltage loss in a vehicle audio power path. Final cable, fuse, and amplifier selection should always follow the amplifier manufacturer's installation requirements.

The 0FO51 is power wire, not speaker wire or RCA signal cable. Its 51-foot spool format offers a continuous length that can be measured and cut for a vehicle-specific routing plan. That can be useful for installations requiring a long front-to-rear battery-to-amplifier run. The orange finish is associated with positive-side power wiring in the Memphis connection-wire range.

Memphis specifies a flexible, protective outer jacket for the 0FO51. This construction is designed to make routing more manageable while helping protect the conductor during installation. The cable is appropriate for use in custom car-audio wiring layouts where cable routing, termination, and circuit protection are planned as part of the overall system. It should be paired with properly sized terminals, a fuse holder, and fuse selected for the connected equipment.

For a complete amplifier installation, the 0FO51 can serve as the main positive power-cable run when its gauge and length fit the system design. A matching ground cable, secure connection hardware, and properly located circuit protection are also required for a typical installation. Memphis lists compatible connection accessories separately, rather than identifying them as included with this spool. Professional installation is recommended when routing through vehicle panels or working near the battery.

Key Features

• 51-Foot Spool: Provides a continuous length for custom-cut installations.
• Oxygen-Free Copper: OFC conductor material supports efficient electrical power transfer.
• True AWG Standard: Built to the gauge specification stated by Memphis.
• Orange Jacket: Makes the cable easy to identify in an installation.
• Flexible Protective Jacket: Helps with routing while protecting the wire.

Design & Installation

The Memphis 0FO51 combines an oxygen-free copper conductor with a flexible, protective orange jacket. It is specified as 0 AWG power wire and supplied as a 51-foot spool. The jacketed construction is intended for dependable routing in a custom vehicle-audio installation.

Measure the planned battery-to-amplifier route before cutting the cable and leave appropriate service length for secure termination. Use terminals, a fuse holder, a fuse, and a ground cable sized for the connected equipment and installed according to the amplifier and vehicle guidelines. Keep the power wire protected from sharp edges, heat sources, and moving parts, and use suitable grommets where it passes through metal panels.
