Big 4 Power Wire Kit

Regular price $34.99

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.*

Big 3

Didnt notice anything considering I have no amps or extra electrical items. I always do big 3 upgrade on all my cars. Best thing to do regardless, plus the wires add color :)

Review title

Great kit, easy to read instructions easy to connect if you have eyes. Fixed my low idle issues and the engine feels a lot smoother through the rev range.

Worth the Money

Relatively easy to install and the wires felt quality. Took maybe 45min with basic hand tools Notes post install: The car starts much faster (The original start speed was already pretty quick) Car Idles Smoother during warm up and cold start Windows roll up faster car Idle doesn't stumble when adding electrical load Headlights DON'T DIM!!!! Cons: I can't really doc any points off for this, but the instructions have a slight typo on them regarding terminal connection points on one of the main power wires. This is an absolute must for anyone who has an aftermarket sound system or are running a stronger ignition setup.
