Was wanting to finish up wiring the power today, and took a look at the 4Ga run I had. It was some cheap no-name cable, and was super light feeling so I decided while I don't want to change the gauge for weight/hiding a huge wire reasons, I was gonna switch the cable out. Ordered 30' of KnuKonceptz Colossus Kandy 4 Ga wire for the new power runs/grounds.
This is the 100% OFC stuff, not the CCA. They oversize everything too, and best of all - it's lime green! Lol.
