4 Gauge AWG Power/Ground Wire Cable 50 Ft Black+50 Ft Red, High Power Shielded CCA Soft Automotive Welding Battery Wiring Kit,for Car Audio Amp...

Includes accessories: 20 high-quality copper terminals, 20 heat shrink tubes (10 black and 10 red, OD 10.00mm, length 5CM). Aluminum foil shielding effectively resists electromagnetic interference, superior to common unshielded cables, resulting in purer sound quality. Constructed from high-quality 4 AWG copper-clad aluminum (CCA, 30% copper), ensuring stable power transmission; CCA is lightweight and flexible, ideal for high-efficiency power needs. Red and black color design allows quick identification and correct wiring, preventing equipment damage. True 4 AWG gauge, OD8.5mm, more reliable for demanding uses like car audio or high-current batteries. The cable features high-quality soft PVC; the internal conductor is composed of high-strand copper-clad aluminum (412 strands of 0.254mm), offering excellent flexibility and ease of installation, easier to bend and route neatly, ideal for wiring in tight or complex spaces such as car cabins. The outer layer uses soft PVC with excellent weather resistance, capable of withstanding extreme temperatures (-50 to +105), and resistant to oil, gasoline, solvents, liquids, abrasion, and impact. Suitable for continuous load current of approximately 6080 amps, with a maximum allowable instantaneous or protected current of 100120 amps. A kind reminder: This is a CCA conductor, not OFC pure copper, but it offers better cost performance and is sufficient to meet power demands in most scenarios, making it the best choice when on a budget.
