Power Cable Selection Chart

Selecting the proper power and ground wire size is an crucial part of amplifier performance and safety. Thicker wire means more current is delivered when needed. In order to select the proper gauge wire you need to determine the maximum current draw of all the amplifiers and processors that you will connect with this wire. You will also need to determine length of wire needed to connect from the battery to the location of your amplifiers and processors.
