PLANNING & INSTALLING
Before beginning the installation, consider the following:
If you plan to expand your system by adding other components
sometime in the future, ensure the adequate space is left, and
cooling requirement are met.
Are your components matched? The peak power rating of your speakers
must be equal or greater than the amplifier. They also must be 2-8
Ohms impedance for the multi-channel Class A/B or Class H amplifiers
and 1-8 ohms impedance for the Class-D Mono-Block amplifier’s.
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 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 circulate freely.
Temperature in car trunks have been measured as high as 155 F in
the summer 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 mounting inside
the passenger compartment since the passenger compartment
will not allow temperatures to reach a critical point. Floor mounting
under the seat is usually satisfactory as long as there is at least one
inch of clearance above the amplifier’s heat sink for ventilation.
1. Select a suitable location that is convenient for mounting,
is accessible for wiring, and has ample room for air circulation
and cooling.
2. Use the amplifier as a template to mark the mounting holes.
remove the amplifier and drill holes. Remove the amplifier
and drill holes. Use extreme caution, inspect underneath
surface before drilling.
3. Mount the amplifier using the screws provided.
Caution: Before connecting any wires to the amplifier, disconnect
the ground lead from the battery. Leave the ground lead
disconnected until you are done wiring the amplifier
