Sonic Exclusive Big 3 Upgrade Combo Package

The Big 3 Upgrade should be the first step you take when adding a aftermarket sound system to your vehicle. The Big 3 consist of upgrading the alternator wire to the battery, the negative battery cable to vehicle ground, and engine ground to chassis. This process is sure to help eliminate dimming headlights and voltage drops by providing you with enough juice to power everything in your vehicle without additional resistance. 1/0 Gauge power & ground wire should be used when executing the upgrade, the thicker wire ensures the best possible current transfer and can re-energize your vehicles electrical system.

Available only at Sonic Electronix is the Ultimate Big 3 Upgrade Kit. This exclusive Big 3 combo package comes with one 10 ft. piece of 1/0 AWG Gunmetal Gray Power/Ground Cable, one 5 ft. piece of 1/0 AWG Blue Power/Ground Cable, two Positive/Negative Battery Terminal Clamps, four 0/2 Gauge Ring Terminals, and a pair of Wire & Cable Cutters to add some convenience to this upgrade.

Benefits of Big 3 Upgrade

  • Helps eliminate dimming headlights
  • Helps stop drops in voltage
  • Enhances your vehicles electrical system stability
  • Allows you to add a second battery or high output capacitor for high powered sound systems
  • Improves vehicles system charging

Primary Color
This is the main color of the item.
Matte Grey
Complies to AWG Standards
Since 1857, The AWG (American Wire Gauge) system has been the standard for measuring the diameter of wire. AWG standard is the measure of bare wire to find true gauge. Companies that do not follow AWG Standards include the thickness of the wire jacket which means the actual wire is not "True to Gauge".
Wire Material
The material that the wire is made of. Copper & aluminum are the most commonly used materials. OFC - Oxygen Free Copper is the ideal choice for wire material. Copper is a superior electrical conductor, & does not expand or contract with heat. CCA - Copper-Clad Aluminum is a suitable choice for lower powered or budget applications. The power transfer is not on par with OFC, but this material offers significant savings.

Big 4!!!!

April 21, 2015

I bought this to strengthen my electrical wiring, in my 08 Honda Civic, and this truly helps. Comes with the necessary accessories to make a clean and pro looking install. Had some wiring leftover and decided to make it Big 4.

Because its Kicker! I would not use any other brand for wiring, amps, or anything! Plus the headquarters is in Oklahoma, the state that i live in.

I already have Kicker wiring in my vehicle and feel confident about their quality of merchandise and would like to keep a consistent look throughout.
Leslie H on Feb 17, 2015
If you running high amperage amplifiers then you've gotta do the "BIG 3." Who wants to damage their amps or any other electrical component in your vehicle. If don't want your lights to flicker, why don't you just ride with Kicker!!! Lol!
