Review on High-Quality Amazon Basics 16-Gauge Speaker Wire Cable, 50 Feet - Reliable and Affordable Sound Solution by April Lee

This wire is made of copper clad aluminum (CCA) instead of copper. CCA wire has higher resistance than copper wire. You can use it normally, but be aware that the distance you can travel with CCA wire is less than copper wire of the same gauge. Educate yourself before running longer distances (20+ feet). For 10-20 foot applications at 8 ohms everything is fine. As a rule of thumb, when using bare copper wire, 16 gauge, 8 ohm (speaker) wire should be no longer than 48 feet. Many home speakers use an impedance of 6 ohms. At 6 ohms, the maximum length is 36 feet. The resistance of CCA wire is about a size smaller than copper wire, so 16 AWG CCA wire should not exceed 32 inches at 8 ohms and 24 inches at 6 ohms.
