Before attempting to drill the mounting holes, take note of any wires, lines or otherdevices
in your vehicle which may be located behind the mounting surface!
Use at least 8 gauge wire for power and ground connections.
Wire the amplifier directly to the car battery.
For the ground connection, use the shortest possible wire to a good chassis ground point.
Wire the Remote connection to the auto start lead of your head unit, equalizer or power antenna.

Pyramid Signature Series amplifiers feature built-in fuse systems. These fuses protect both the
amplifier and the electrical system in your vehicle from fault conditions. If you ever need to replace
the fuse in your Pyramid Signature Series amp, use a fuse of exactly the same type and rating. A
different type or rating of fuse may result in damage or fire.
