Power Cable Selection Chart

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