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 Silver Power/Ground Cable, 5 ft. piece of 1/0 AWG Blue 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

Real true to awg standards, 100% ofc wire. Its legit, and does help with my voltage drops. The best thing has to be the terminals though, they are sick. Any gauge, multiple batterys, multiple amps, anything they can be used for.

I should have bought this with my system as its far more expensive buying 0 gauge here in Australia, this is great stuff at a great price. Only reason im not getting it now is because USPS takes over 3 weeks and I am willing to pay more to get my system running sooner but if your looking at buying sub(s) and an amp that require over 1000rms definately think about getting this with it.

I just upgraded all the cables for my "big three upgrade" using this kit. I put it in an 07 toyota and it tremendously helped my 1200 watt RMS speaker and sub system. Thanks Sonix!

The ring terminals for the 1/0 AWG are too small even with taking out the spacers that are on the inside of them. The ring terminals also have very cheap screw heads that will round off or start to strip because its a non hardened metal. Same goes for the battery terminals, you can not get the wires inserted perfectly without cramming them in and then it leaves it looking messy. The wire and cutters are good quality and it is a fair price. The cutters are very sharp which made cutting the wires extremely easy!

The ring terminals and the battery terminals were both too small to fit true 1/0 AWG wire into them. With the ring terminals I even took out the inside spacers and it still barely fit. The ring terminals are low quality because the screws to secure the wire inside of them are just too cheap of a metal because it's not hard enough metal to take the torque. I ended up stripping the head of them. I really liked the wire cutters, they were sharp and cut cleanly through the wire with no problem.
