Review on 🔌 GS Power 10 Gauge CCA Automotive Wire: 100ft Red & 100ft Black for Car Audio, Amplifiers, Model Trains, and Drone Wiring by Omar Card

This is not 10 gauge wire. Go to your local hardware store and compare to the 10 gauge stranded wire they sell. The insulation almost doubles the gauge of the wire, plus CCA instead of OFC (which is what's advertised, so no surprise) making it less conductive than expected. Next time I'll buy a few bucks more locally for the real specs.
