Step 2: Wiring the Amplifier
The amplifier will be powered directly by the battery. This will involve running heavy gauge wires from you car battery to the amplifier. Read the instruction manual of the amplifier to determine the necessary wire gauge for powering the amplifier. There are kits online that have pre-packaged wire for amplifiers or you can save yourself some money and go to the local hardware store and get them to cut a few feet of wire for you.
