Skar Audio 1/0 Gauge OFC Big 3 Complete Upgrade Electrical Wiring Kit, SKBIG3-0GA

More than enough length for my car, tinned OFC wire, Skar branded heatshrink is nice too.

Great for big 3 easy install

Super good quality build. Works great, installs easy on a 2016 silverado 1500.

Husband was really satisfied.

Got this and put it on a 07 Pontiac Grand Prix, just recently finished putting it on. I needed to replace my battery terminals, so I went ahead and bought this. My main reasoning behind getting this is to hopefully try to help out my alternator(which has 181k miles on it).Ran it from the alternator to the battery, and then replaced the power cable running from the battery to the fuse box(with some of the wire from this kit). Ran the cable from the ground terminal to the chassis, and then from the same grounding point as the ignition system(which should be good enough) to the chassis.The only problem I ran into was the hole for the final cable(going from the block to chassis) was just barely too small, I had to end up drilling it out bigger to get it to fit. Cables seem to be atleast decent, not as good as what the factory cables are(the factory ones was far more stiff unlike this), it did make it easier to run and is easily better overall.This kit does seem to have a good value to it, getting the equivalent amount of 0 guage wire would cost around the same, but not give the wire connectors for it or any cable managing items like what this kit gives.I can't say for how effective this might be, but I do remember my interior lighting dimming down when listening to music, and I dont recall the same thing happening any more, I will need to double check on this and edit this review after.

This wiring kit is excellent! The wires are a good length, high quality, and very easy to work with. The included connectors are also top-notch. I've had no issues with heat, even in the engine bay, and it feels very durable. Great value for the money!

Have had this installed for a few months now and no issues and good quality. Not as much copper as some of the others that use oversized 1/0 but again, no issues and for the price it is a great value.

Great tinned ofc big 3 kit. I was worried about the length of the main power from the alternator because it was on the lower opposite side of the engine bay, but I ended up with around 10" of extra after following the existing routing through the harness. All in all, for the price it's great and actually is 4 gauge ofc if you're worried.
