Be safe and always calculate the gauge wire are you need, don’t cut corners.
Size: 4 Gauge 10FT
Good quality solid copper 4 Gauge wires in red and black. Avoid aluminum wiring that has copper plating so looks like solid copper but can be dangerous if used in heavy load applications. Copper is expensive but required if amperage is high.

Durable insulation and pure copper not that cca bs
Size: 1/0 Gauge 5FT
Good quality. Solid copper, not that cca bs. Stiff and durable insulation. Used for big 3 car audio grounds on high output alternator. Great results. Will mention that it’s not as thick as some other brands but not by much. Terminals still crimped tightly with 1/0 gauge
