What in the world is a Big3 Upgrade and is it right for you? Simple answer, a Big3 Upgrade is basically an electrical stress reliever for your vehicle's charging system, so yes it is very beneficial, and sometimes even necessary! Comprised of a series of wire gauge upgrades under the hood, the Big3 Lessens the burden placed on stock wiring, and allows all your 12 volt accessories to function better by lessening the risk of electrical inefficiency. A typical Big3 installation consists of an upgraded power wire between the alternator's charging post and the stock position battery's positive terminal, a Ground wire upgrade from the alternator bracket or engine block to a frame point, and another Ground upgrade from the stock position battery's ground post to a frame point. These 3 short runs of wire make a tremendous difference when improving the overall electrical health of your car audio system.
