-Pull the panels that hold the carpet down and run the power wire through to the trunk
-Pull your headunit and run your RCA and remote wire the same route as the power wire
-Find a place to mount the amp
-You can fuse the power wire again right before the amp, or use a fused distro-block
-Connect everything
-Fuse the power wire 18" from the battery
-Connect to battery
-Hook Neg on battery back
-Tune amp.
