Review on GS Power 12 Gauge Stranded Copper Clad Aluminum Wire: Car Audio Amplifier Wiring Assortment, 6 Color Combo – 50ft Roll by Brian Page

It's CCA, so yeah, not AWG, not really 12G. But I built a custom wiring harness for my truck. I have used this cable in all required GM colors: red, black, yellow, brown, pink, tan, blue, green, purple, grey, etc. All cables are 12G CCA cables. They cut easily, crimp and solder perfectly. All wires are terminated with either non-insulated butt connectors covered with heat shrink tubing or Delphi WeatherPack connectors. So far nothing has broken. I used about 500 feet of these flowers.
