If you're upgrading your stock alternator to a high output alternator, it is required to upgrade your wiring to a big 3-wiring upgrade kit. A common myth is that you don't need to upgrade your wiring if you aren't running an aftermarket car audio system or other aftermarket products. However, this is not true. Big 3 wiring kits are ALWAYS required when upgrading to a high-output alternator.
The Big 3 Wiring Upgrade Kit comprises high-quality wiring materials designed to increase power transfer from the battery to other electrical components in a vehicle, including amplifiers, subwoofers, and speakers. A High Output Alternator further increases this power by generating a higher current than traditional alternators typically produce.
This article will examine the benefits of these upgrades when combined with proper installation techniques and knowledge.
