Rockford Fosgate RFW8B 250-Foot 8 AWG Black Power Wire

The Rockford Fosgate RFW8B is a 250-foot bulk spool of 8 AWG frosted black wire for car-audio power and ground wiring projects. It gives installers a long continuous supply of cable for custom-length runs rather than pre-cut leads. The black insulation is suited to organized, color-coded system wiring where black cable is desired.

This cable is intended for installers and enthusiasts building or upgrading vehicle audio systems that call for 8 AWG wire. Its full-spec 8 AWG construction helps ensure the conductor size corresponds to the stated gauge. The bulk spool format is especially practical for multi-vehicle work, larger custom installations, or projects requiring several cable runs.

The RFW8B uses Pure Crystal-Oxygen Free Copper (PC-OFC) conductors with 735 strands. Its multi-strand construction and frosted outer jacket are designed for flexibility during routing. That flexibility can make it easier to guide the cable through a vehicle while maintaining a clean installation path.

Rockford Fosgate lists the cable as conforming to the CEA-2015 industry standard and meeting or exceeding AWG specifications. It also carries a BC-5W2 designation for use on boats and non-commercial marine vessels. These stated construction standards make it a purpose-built option for mobile-audio wiring applications.

Use the RFW8B where an amplifier, distribution component, or ground connection specifically requires 8 AWG cable. Select compatible terminals, fuse protection, and connection hardware separately for the equipment being installed. Confirm the amplifier manufacturer's wire-gauge and fuse requirements before planning the final system wiring.

Key Features

• 250-Foot Bulk Spool: Provides substantial cable length for custom installation runs.
• 8 AWG Full-Spec Cable: Meets or exceeds stated AWG requirements.
• PC-OFC Conductor: Uses Pure Crystal-Oxygen Free Copper construction.
• 735-Strand Design: Multi-strand conductor supports flexible cable routing.
• Frosted Black Jacket: Flexible outer jacket provides a clean black finish.
• CEA-2015 And BC-5W2: Listed to CEA-2015 and BC-5W2 specifications.

Design & Installation

The RFW8B combines a 735-strand PC-OFC conductor with a frosted black outer jacket. The cable is built as full-spec 8 AWG wire, with a stated conductor area of 8.36 mm². Its black jacket supports visually consistent ground wiring or other installations that call for black cable.

Measure each route before cutting from the 250-foot spool and leave appropriate service length at connection points. Use terminals and hardware sized for 8 AWG cable, and follow the connected amplifier or electrical component's instructions for wire gauge, fusing, grounding, and routing. Keep power wiring protected from abrasion and avoid routing near moving or high-heat vehicle components.
