This is not pure copper but CCA (Copper Clad Aluminum). However, if your audio system doesn't cost more than your car, it will offer superior performance and save you a decent amount of money. I use it over relatively short distances to connect to my surround speakers and it works just as well as the copper cable I use with other speakers. The sheath is thick but retains decent flexibility for a 14g wire. No problem with stripping wire ends for connections. Great value for money.
