Sonic Exclusive Big 3 Upgrade Combo Package

The Big 3 Upgrade should be the first step you take when adding an 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 vehicle's electrical system.

Available only at Sonic Electronix is the Ultimate Big 3 Upgrade Kit. This exclusive Big 3 combo package comes with two 5 ft. pieces of 1/0 AWG Metallic Gray Power/Ground Cable, one 5 ft. piece of 1/0 AWG Metallic Powder 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
  • Increases compatibility when using high performance alternators and batteries
  • Strengthens power current to everything in your vehicle without additional resistance
Note: For information on installing this Big 3 Upgrade kit, please read our blog and watch the step by step installation video.

Exceptional Quality

The following review is for XW0GR5, which is a part of the bundle you are viewing.

Some of the best quality wires I've ever used. My car stereo system is wired mostly with nvx power wires. I was totally impressed with the difference in voltage increase which lead to a overall better sound quality.

Made a Difference

The following review is for XW0GR5, which is a part of the bundle you are viewing.

Hi all. I decided to try this wire. Because of the Price I decided to Upgrade my Ground wires from 4 Gauge. Both the Capacitor and from the Battery to Ground (Body). Afterwards I noticed the Voltmeter on the Capacitor increased slightly. About .2V. When I get enough money, I am Upgrading the Power (+) wiring. BTW, I am running Kicker IX500.1. And plan on Upgrading to the IX1000.5. So I want to get the Wiring (To the Cap) done first. And like others have said, This wire for being 1/0 Gauge is Very Flexible. Which I am surprised at since I have never used this gauge before.

True Gauge

The following review is for XW0GR5, which is a part of the bundle you are viewing.

Big ground wire, extremely flexible for a 0 gauge wire and in my opinion it surpasses the 0 gauge wire standards. Great product from NVX once again.

Great Stuff

The following review is for XW0GR5, which is a part of the bundle you are viewing.

Very flexible and durable. True gauge. Used this to wire up my amps and also used some of it to do the "big 3." I liked NVX so much that I stripped out all my speaker wiring and bought 16 gauge NVX wire and ran that instead.
