Before Beginning The Installation; Mounting Your Amplifier - Alphasonik PM12005E Owner's Manual

Before beginning the installation, consider the following:
A. If you plan to expand your system by adding other components sometimes in
the future, ensure that adequate is left, and cooling requirements are met.
B. Are your components matched? The peak power rating of your speakers
must be equal or greater than the amplifier's. They also must be 2-8 ohms im-
pedance (This information is normally printed on the speaker magnet).
C. Consider the length of your leads which should not be too long or short when
determining the mounting location. Pre-Amp input jacks require a length of high
quality shielded male to male RCA patch cord.

Mounting Your Amplifier

The mounting position of your amplifier will have a greater affect on its ability to
dissipate the heat generated during normal operation. This amplifier has ample
heat sink for heat dissipation, and is designed with a thermal shutdown circuit
(for heat protection). DO NOT enclose the amplifier in a small box or cover it so
that air is not able to flow freely.
Temperatures in car trunks have been measured as high as (155 F) in the sum-
mer time. As the thermal shut down point for the amplifier is (185 F), it is easy
to see that it must be mounted in an area that provides for maximum cooling
capability. To achieve maximum advantage of convection air flow in an enclosed
trunk, mount the amplifier in a horizontal position.
Cooling requirements are considerably relaxed when the mounting inside the
passenger compartment since the driver compartment will not allow tempera-
tures to reach a critical point. Floor mounting under the seat is usually satisfac-
tory as long as there is at least 1 inch of clearance above the amplifier's heat
sink for ventilation.
A. Select a suitable location that is convenient for mounting, is accessible for
wiring, and has ample room for air circulation and cooling.
B. Use the amplifier as a template to mark the mounting holes. Remove the am-
plifier and drill holes. Use extreme caution, inspect underneath surface before
drilling!
C. Secure the amplifier using the screws provided.
Caution: Before connecting any wires to the amplifier, discon-
nect the ground lead from the battery. Leave the ground lead
disconnected until you are done wiring the amplifier.
