Memphis 4FO100 4 AWG Orange OFC Power Wire, 100 Ft

The Memphis 4FO100 is a 100-foot spool of 4 AWG orange power wire for vehicle audio installations. It provides the bulk cable needed to route amplifier power through a custom car-audio system. This is a connection product rather than an amplifier, speaker, or signal processor.

This wire is intended for installers and DIY enthusiasts building or refreshing an amplifier power run. Its 100-foot spool format is useful when multiple runs, custom cable lengths, or more than one installation are planned. The orange jacket makes it easy to identify within a power-wire layout.

Memphis specifies oxygen-free copper construction to support efficient electrical power transfer. The wire is built to the true AWG standard, so its 4 AWG designation is intended to match the stated conductor size. Proper wire sizing is an important part of supplying an amplifier from the vehicle electrical system.

A flexible, protective jacket surrounds the conductor for easier routing and added protection during installation. That construction helps the cable follow vehicle contours while keeping the insulated run organized. The product is supplied as orange power wire on a 100-foot spool.

The 4FO100 fits into a system upgrade path wherever a 4 AWG power cable is appropriate for the amplifier and installation design. It should be paired with correctly sized terminals, a fuse holder and fuse, and other installation hardware selected for the specific system. Professional installation is recommended when routing power cable through vehicle panels or near the battery.

Key Features

• 4 AWG Size: Provides a substantial power-wire gauge for compatible amplifier installations.
• 100-Foot Spool: Supplies bulk cable for custom-length power runs.
• Oxygen-Free Copper: Uses OFC conductor material for electrical power transfer.
• True AWG Standard: Maintains the manufacturer-stated 4 AWG wire sizing standard.
• Orange Jacket: Helps identify the cable in an organized installation.
• Flexible Protective Jacket: Supports routing while protecting the insulated conductor.

Design & Installation

The 4FO100 uses an oxygen-free copper conductor with an orange, flexible protective jacket. Memphis identifies it as power wire and supplies it on a spool, allowing the installer to cut cable to the required length. Its true-AWG construction is intended to provide the stated 4 AWG wire size.

Use this wire for a compatible amplifier power run and plan the route before cutting. Select terminals, fuse protection, and other connection hardware that match the amplifier requirements and the vehicle installation. Keep the cable protected from sharp edges, heat sources, and moving components, and follow the amplifier and vehicle manufacturers' installation guidance.
