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

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.

Never dipped down in power after using this Big 3 power kit

Thank you

First off the package was missing the assortment of connections wire hangers and whatever elsa that's so post to be in the bag..also to boot the wire is not 1/0 gage.. I have 4 gage wire that is bigger..i was really looking forward to this set being a company with a decent products...guess not don't waste your money

Easy to install .. even has directions in the back of the box on how to wire it up

I like so far

Supper fast shipping and everything is in box

(This product is tinned copper wire) There is bare copper, tinned copper, and CCA/copper clad aluminum in the three pictures I posted. First of all you have bare copper. Most everyone knows and recognizes this wire. It's just bare red copper. It's highly conductive and is adequate for most of your electrical needs but is susceptible to corrosion caused by moisture which can limit it's effective lifespan. Next there is tinned copper wire. If you've done any soldering of wire for any reason you will likely have tinned the tips of wires yourself. Tinned copper wire has the same conductivity as bare copper wire but with a few added benefits. It is much more corrosion resistant. The lifespan of tinned copper is a great deal longer than that of bare copper. Tinned copper also makes soldering a bit easier as the entire wire is already tinned. Lastly is copper clad aluminum. This is aluminum wire with a thin layer of copper coating on it's surface to increase it's conductivity. Copper is simply more conductive than aluminum, meaning electricity can flow through it more easily while encountering less resistance. Copper clad aluminum is the least durable and least conductive of the three. It's also the lightest and cheapest. Making it good for reducing weight and saving money. I do not recommend using copper clad aluminum for anything if you are not well educated on the topic. It's the most likely to break. It has the most resistance meaning the most heat which can result in fire or melting if not properly used but if used correctly for the right applications it also has it's place. Keep in mind that to get the same performance from CCA you will need to use about two and a half times as much. This means that it loses value and weight efficiency as the power of your project increases. I hope this is helpful information.

Fits perfect, nice paint job
