Power
To avoid unwanted ignition noise caused by ground loops, it
is
essential that the
Amplifier be grounded to a clean, bare, metal surface of the vehicles chassis.
Note
:
GROUND WIRE SHOULD NOT BE EXTENDED MORE THAN
3
FT
(I
METER).
Planning and Mounting Your System

The mounting position of your Amplifier wlll have a great effect on its ability to
dissipate the heat generated during normal operation.
Under normal conditions, the
heatsink will dissipate sufficient heat to avoid thermal
shutdown. However please do not install the amplifier in a wooden box or similar
device as this will prevent heat dissipation into the atmosphere.

Temperatures in car trunks have been measured as high as
(1
55'F)
in the summer
time. since the thermal shut-down
point for the amplifier
is
(1
58'F)
it
is
easy to
see that it must be mounted 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 driver will not
offen allow temperatures to reach a critical
point. Floor mounting under the seat
is
usually satisfactory as long as there
is
at least
1
inch of clearance
(2.54
cm) above the Amplifier's fins 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 Amplifier
and drill holes. Use extreme caution, inspect underneath surface before drilling!
C.
Secure the Amplifier using the screws provided.
