Don’t get me wrong it’s not a horrible product but these wires have an extreme amount of resistance to them, and once they get hot they drop voltage drastically. It was nice it came with a bunch of eyelets and made it easy to assemble but unfortunately once they were over 100F temp (live in Florida so cars get way hotter than that on the inside) the voltage would go from a normal 12.5-13.5v all the way down to 8v. Partially my fault I did not notice they were CCA wire instead description, would not recommend for automotive use.

Low quality. Recommend something from a better brand.

Low quality. Seemed fine until the first one I ordered one of the terminals broke off with very little tightening force. The replacement i had ordered worked for a few days then quit working altogether. Overall disappointed.
