1/0 AWG Pure Crystal OFC Red Wire 51 Foot Spool, 53.5mm², 4,704 Strands, Frosted Flexible Outer Jacket. Full AWG Specification.

Product Overview

The Rockford Fosgate RFW1R-51 is a 51-foot spool of 1/0 AWG (53.5mm²) red insulated multi-strand power cable Pure Crystal Oxygen-Free Copper (PC-OFC) construction with a frosted outer jacket for maximum flexibility. This is the red (positive) counterpart to the RFW1B-51 black wire spool identical conductor specification in the conventional positive-polarity colour. The cable meets or exceeds full AWG specification. Suitable for main power runs from the battery to high-power amplifiers in car audio installations.

Features & Benefits

• 1/0 AWG — Heavy Gauge for High-Power Systems — 1/0 AWG at 53.5mm² is appropriate for main power and ground connections on high-power car audio installations — typically amplifier systems rated at 1,000W RMS and above depending on the cable run length.
• Pure Crystal OFC — PC-OFC Conductor — Large-crystal copper production minimises grain boundaries for lower resistance and better conductivity than standard OFC copper of the same gauge.
• 4,704 Strands — High Flexibility — 4,704 individual strands provide the flexibility needed to route 1/0 AWG cable through vehicle firewalls, door sills, and boot entry points without kinking.
• Frosted Red Jacket — Positive Run Convention — The red frosted jacket follows the standard car audio installation colour convention for positive (+12V) power runs, ensuring clear polarity identification at both ends of the cable run.
• Full AWG Specification — Meets or exceeds the AWG requirements for 1/0 AWG conductor cross-section — the confirmed 53.5mm² meets the full specification, not a reduced-cross-section "AWG-labelled" product.
• 51 Foot Spool — Approximately 15.5 metres — sufficient for a complete vehicle power run with routing and working length.

Frequently Asked Questions

What is the RFW1R-51 used for?

The RFW1R-51 is a 1/0 AWG red positive power cable used for the main supply run from the vehicle battery to high-power car audio amplifiers. Red is the standard positive (+12V) colour convention in car audio wiring.

How does the RFW1R-51 differ from the RFW1B-51?

Both are identical in conductor specification — 1/0 AWG, 53.5mm², 4,704-strand PC-OFC, full AWG spec, 51-foot spool. The only difference is jacket colour: RFW1R-51 is frosted red (positive convention), RFW1B-51 is frosted black (negative/ground convention).

How long is 51 feet in metres?

Approximately 15.5 metres. This is sufficient for a complete battery-to-amplifier power run in most passenger vehicles, with routing and working length included.

Does the red jacket affect the electrical performance?

No — the jacket colour is a convention for polarity identification only. The conductor specification is identical between the red and black spools.

What fuse is required for a 1/0 AWG power run?

An inline fuse must be installed within approximately 450mm (18") of the battery positive terminal for any positive power cable run. The fuse rating should be appropriate to the amplifier's maximum current draw. Confirm compatible 1/0 AWG fuse holders and ratings with Rockford Fosgate or your installer.
