The built-in protection circuitry in the pyramid
Arctic amplifiers will disable the amplifier if it
senses an input overload, a speaker short
circuit, or extreme temperature conditions.

When the protection circuit is activated by any
of these conditions,

If this occurs ,carefully inspect the system to
determine the source of the problem.

If the shutdown was a result of a thermal overload
condition, allow the amplifier to cool down before
attempting to restart it.

If the shutdown was a result of an input overload,
or speaker short circuit, be sure to corr the
condition before restarting.

mounting and installation

Your new PYRAMID Arctic 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 high­power electronic device capable of generating high heat.

For this reason,

always choose a location in your vehicle which has low

Be sure to mount the amp

to allow reasonable airflow over the cooling fins.

Mark the location for the mounting screw holes by positioning the amp where you

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

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

Use at least 8 gauge wire for power and ground connections.

Wire the amplifier directly to the car battery.

About power fuses:

Pyramid Arctic 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 Arctic Series amp, use a fuse of exactly the same type and rating. A
