We love bolting stuff to our 4×4’s, and we know that you do too!
However, some 4×4’s only come with tiny Alternators, or Smart Alternators that reduce the output of the Alternator unless the computer decides the output needs to go up.
So before adding all of your accessories, do some quick math by punching in the wattages below, and we’ll spit out a number of how many Amps you need in the system to support those accessories.
This calculator does not include the power draw from your factory systems. Please contact your manufacturer to find out how much power your vehicle uses, and how much is available for accessories.
