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 Tsunami Ultimate Big 3 Upgrade Kit. This exclusive Big 3 combo package comes with two 5 ft. pieces of 1/0 AWG Black Power/Ground Cable, 5 ft. piece of 1/0 AWG Red Power/Ground Cable, one Positive/Negative Battery Terminal Clamp, 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
Includes Everything You Need To Upgrade The Big 3 Note: For information on installing this Big 3 Upgrade kit, please read our blog and watch the step by step installation video.
