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 Speaker RV Trailer Marine Solar+ Lugs&Heat Shrink Tubes

Includes accessories: 20 premium copper terminals and 20 heat shrink tubes (10 black and 10 red, OD 10.00mm, length 5CM). Aluminum foil shielding effectively resists electromagnetic interference, outperforming common unshielded cables for cleaner sound quality. Constructed from high-quality 4 AWG copper-clad aluminum (CCA, 30% copper), ensuring stable power transmission; CCA is lightweight and flexible, perfect for high-efficiency power requirements. The red and black color scheme enables quick identification and proper wiring, helping to prevent equipment damage. True 4 AWG gauge with an OD of 8.5mm delivers reliable performance for demanding applications like car audio or high-current batteries. The cable utilizes high-quality soft PVC. The internal conductor consists of high-strand copper-clad aluminum (412 strands of 0.254mm), providing excellent flexibility and ease of installation, making it simpler to bend and route neatly, ideal for wiring in confined or complex spaces such as car interiors. The outer layer employs soft PVC with outstanding weather resistance, capable of enduring extreme temperatures from -50°C to +105°C, and is resistant to oil, gasoline, solvents, liquids, abrasion, and impact. It is suitable for a continuous load current of approximately 6080 amps, with a maximum allowable instantaneous or protected current of 100120 amps. This CCA conductor is not OFC pure copper but offers superior cost performance and is sufficient to meet power demands in most scenarios, making it a practical selection on a budget. It is widely used in various car audio systems, vehicle amplifiers, generators, solar systems, boats and RVs, motorcycles, golf carts, grounding, and welding wires. Whether for home audio systems, radio equipment, or industrial applications, it supplies stable power support to meet high-power transmission needs
