Review on 🔌 High-Quality 14 Gauge Flexible Copper Clad Aluminum Low Voltage Primary Wire 6 Color Set - 100ft Roll, Perfect for 12 Volt Automotive, Trailer Harness, Car Audio, and Video Wiring - 600 ft Total by Jay Matlock

The quality of the cables is the same as Audiopipe/Best Connection which means they are slightly smaller than the AWG standard. Maybe they use some kind of Chinese measurement standard. I like the fact that the number of strands and the diameter of the strands are clearly indicated by the seller. I checked the number of strands, they are accurate. The insulation is very thick and must withstand the weather. Remember this is CCA or copper clad aluminum wire which means each strand has a copper clad aluminum strand on the surface. For DC and low frequency applications, you'll probably want to reduce the resistance by a thickness or two to have comparable resistance to oxygen-free copper wires (oxygen-free copper). For high-frequency applications in the MHz range, the performance can be comparable due to the current density on the surface layer. In any case, the price is unbeatable and I am completely satisfied with the use. 16 gauge oxygen free copper wire costs 2-3 times more than 14 gauge CCA wire.
