Big 4 Power Wire Kit

$34.99
28 reviews

This kit is made to upgrade your factory positive and negative wires to increase your cars electrical system. By increasing the size of the wire, it will raise the alternators output voltage which will improve everythings performance that uses the 12 volt system. For example, ignition, steering, stereo, headlights, etc. When we installed this on our shop Sonic it bumped the voltage .3, other people have reported more. We are not tricking the alternator to put out more voltage, we are just allowing the full voltage from the voltage regulator to make it to the fuse panel and battery. Whatever output voltage you have must have a better ground as well, so we include 2 upgraded ground wires as well.

The Cruze comes with 1 less wire than the Sonic.

The install was pretty easy just make sure you unhook the battery haha. I did notice my lights were brighter and my stereo was louder and more crisp. I just put the new wires over the stock ones. I really didn’t want to undo all the wiring.

Big power wire kit

The kit was easy to install and was a great idea. The only issue was the engine ground could be longer so it could be tucked away better. Thanks guys, nice product

No more dimming.

This kit works perfectly. The directions have some typos in important places but as long as you know what you're looking at you should be fine as it's pretty straight forward. After install, my headlights don't dim when the compressor kicks on and and nothing ever bogs down, it stays running like it should.
