mounting and installation

Your new Pyramid Signature Series amplifier comes complete with required mounting hardware. When determining a suitable location in your vehicle for the amp, please remember that it is a high- power electronic device capable of generating high heat.

For this reason, always choose a location in your vehicle which has low vibration, adequate

ventilation, a minimum of dust, and no moisture.Be sure to mount the amp in such a manner as to allow reasonable airflow over the cooling fins.

Mark the location for the mounting screw holes by positioning the amp where you wish to install it and use a scribe (or one of the mounting screws) inserted in each of the mounting holes to mark the mounting surface for the mounting surface. If the mounting surface is carpeted, measure the hole centers and mark with a felt tip pen.

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! Then drill pilot holes in the mounting surface for the mounting screws and insert them. Tighten the screws securely.

When making electrical connections to your amplifier, please observe the following	21
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.

About power fuses:

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.
