4 Gauge 4 AWG Power/Ground Wire 35 ft Black + 35 ft Red - Flexible

Our review of the HiFind 4 gauge power and ground cable finds it best suited for DIY car audio, RV, solar and generator DC wiring where flexibility and true-to-gauge labeling matter. The single biggest reason to buy is that it delivers a genuine 4 AWG profile with a soft-touch PVC jacket and copper-clad aluminum conductors that balance weight and conductivity, making routing and installation in tight spaces noticeably easier than stiffer alternatives.

Key Features

• True 4 AWG wire: Meets the American Wire Gauge standard so installers get the gauge they expect for power delivery and fuse sizing.
• CCA construction with 30% copper: Copper-clad aluminum provides improved conductivity over plain aluminum while keeping cable weight and cost down.
• Soft-touch PVC jacket: A flexible, abrasion-resistant 90 mil jacket helps route wires through tight spaces and resists common garage and vehicle hazards.
• Wide compatibility: Rated to 600 volts and suitable for car audio, RV, solar, and generator DC applications where high-voltage batteries are used.
• Temperature and chemical resistance: The cable is engineered to withstand a wide temperature range and resist solvents and battery acid for under-hood and marine use.
• 2-year warranty: Coverage for defects in the first two years provides a practical safety net for regular installers and hobbyists.

Who It's For

The cable is ideal for car audio enthusiasts installing high-power amplifiers, DIY RV or marine electrical work, and hobbyists wiring small solar or generator systems who need a flexible, true-spec 4 AWG run that is easier to bend and tuck than rigid copper bundles. Installers who value a lighter cable and softer jacket for routing in crowded engine bays or behind panels will appreciate the handling.

Those who need the absolute best conductivity per cross-section or who prefer pure OFC copper for maximum current capacity and long-term corrosion resistance should consider full copper alternatives. Also, if a project requires extreme continuous current beyond typical automotive or RV installations, specify cable and terminals rated for that application.

Pros & Cons

Pros

• True-to-gauge 4 AWG sizing makes fuse and terminal selection straightforward.
• Flexible soft-touch jacket simplifies routing through tight spaces and improves installation speed.
• Good value for money with CCA construction offering a balance of conductivity and lower weight.
• Wide application range and a two-year warranty offer peace of mind for many DC projects.

Cons

• CCA is not pure copper, so pure OFC copper will still outperform it for maximum long-term conductivity and corrosion resistance.
• Some customers report the wire feels thin compared with heavy-duty copper, which may concern those expecting a stiffer, heavier cable.

Specifications

Our Verdict

The HiFind 4 AWG 35 ft red and 35 ft black cable is a sensible, cost-conscious choice for car audio installers, RV owners and DIYers who need a flexible, true-spec power and ground run. It combines easier handling and a rugged soft-touch jacket with CCA conductors that deliver good performance for most DC applications, making it a practical value buy when full copper is not required.

Frequently Asked Questions

Is this cable suitable for car amplifier power runs?
Yes, it is suitable for car audio amplifier installations and similar DC power runs where a true 4 AWG conductor is required.

Can this wire be used outdoors or in marine environments?
The soft-touch PVC jacket resists solvents, battery acid and abrasion, making it appropriate for protected outdoor and marine use, though terminals and connections should be protected from prolonged salt exposure.

Does the cable contain pure copper?
The conductor is copper-clad aluminum with about 30% copper, which balances conductivity and weight but is not the same as pure OFC copper.
