Installing the amplifier - Running the power
To install the amplifier, you'll need to first wire up the power wire (with fuse) directly to the battery. To go through the firewall, be sure to use a grommet.
Remember to route your main power wires away from the radio wires. I chose to route the power down the side of the Jeep, and the radio wires down the center.
To install the amp's ground wire, you'll need to find a good strong bolt into the body, then sand off the paint and bolt down the wire. I used the rear seat bracket for my ground spot.
