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

Well made, a solid connection.
Size: 6 Pairs / 12 pcs
I liked them. They really lock down on the speaker wire to make a firm connection. They seem well made and are easy to install. My system sounds great.
