Quantity "1" = 1 Foot • Quantity "8" = 8 Continuous Feet
All orders ship as one continuous length so you can build your run exactly how you want it.

Looking for true OFC performance, maximum flexibility, and clean, reliable power transfer? Our 4GA OFC Power & Ground Wire is engineered for serious systems that demand the best. Whether you're rewiring a full car audio build or laying out a clean, dependable electrical system in another application - this wire delivers. We often get asked questions for use in the Solar, Marine, Motorcycle, Side-By-Side, Off-road, Rv & trailer industries. Our wire is capable of being your Power or Ground cable in most applications.

Our Oxygen-Free Copper (OFC) wire is built to outperform CCA and lower-quality copper blends. You get:

• Lower resistance for stronger voltage delivery

• Higher strand count for improved power transfer

• Superior flexibility for tight bends, amps racks, and routing through vehicle channels

• Long-term reliability with no oxidation issues that plague cheap wire

If you're tired of stiff, brittle wire or exaggerated "gauge" claims, our OFC is the upgrade your project deserves.

Match your build, color-code your runs, or keep your install clean and organized.
Choose from:
Black • Red • Blue • Lime Green • Silver • Orange • Purple • White

(Colors are identical to the rest of the SHCA wiring lineup - perfect for full-system uniformity regardless of gauge.)

We use a proprietary jacket blend that's both rugged and extremely flexible. It protects against abrasion, heat, vibration, and harsh routing paths - all while staying easy to work with in tight spaces.

Inside the jacket, our high-strand OFC bundle uses optimized strand thickness and layout to maximize flexibility and conductivity. This means smoother routing, tighter bends, and better overall power flow to your amplifiers or accessories.
