The Big 3 Upgrade



Doing the Big 3 Upgrade will improve your cars electrical system as well as its Current Handling. This should actually be one of the first modifications when upgrading your sound system. The factory wiring is great for basic systems. I would recommend doing your Big 3 Upgrade using 0 Gauge wire. It has a great current flow with very little resistance. This new decrease in resistance will reduce light dimming, reduce voltage drops, stabilize voltage and current flow, and decrease the strain being put on your vehicle’s electrical charging system.

What gets Upgraded:

  • Alternator positive cable that runs to the positive terminal of the battery

  • Negative battery cable that runs from the battery to the vehicles chassis

  • Chassis grounding cable that runs to the engine block
