Review on Pyle 50ft 12 Gauge Speaker Wire - High-Quality Copper Cable on Spool for Seamless Audio Stereo Connection to Amplifier, Surround Sound System, TV Home Theater, and Car Stereo - PSC1250 by Eric Nelson

This is not 100% copper wire, it is copper plated aluminium. It doesn't say anywhere that it's copper plated, but it's marked as copper speaker wire. Misleading Advertising. This wire does not solder well. If you're on a budget and using crimp connections, this wire is fine as long as you don't bend the wire too much (aluminum breaks more easily than copper under stress) or you don't need a lot of current for your speakers. (no audiophiles), then this cable will do.
