AudioBahn A4002J - Planning;Mounting Your System

Planning Your System
Before beginning the installation, consider the following:
a. If you plan to expand your system by adding other components sometime in the
future, ensure that adequate space is left, and cooling requirements are met.
If your radio/source is equipped with Pre-Amp outputs, it is possible to utilize
them to drive an Amplier and connecting (Amplier) to the 2 rear speakers.
Then, use the built-in power of your radio to drive the 2 front speakers.
NOTE:
DISTORTION LEVEL IS CONSIDERABLY LOWER FROM PRE-AMP (LOW LEVEL) OUTPUTS, THAN
SPEAKER (HIGH LEVEL) OUTPUTS.
b. Are your components matched? The RMS power rating of your speakers must
be equal or greater than the Amplier’s. They also must be 1-8 Ohms
impedance (this information is normally printed on the speaker magnet).
c. Consider both the length of your leads, and routing when determining the mounting
location. Pre-Amp input Jacks require a length of high quality shielded male to male
RCA patch cord.
Mounting Your System
The mounting position of your Amplier will have great effect on its ability to dissipate the heat generated
during normal operation. It has an ample heat sink for heat dissipation, and also is designed with a thermal
shut-down (for heat protection) circuit, having enough air directed over the cooling ns will improve heat dis-
sipation dramatically. DO NOT enclose the amplier in a small box or cover it so that air can not ow around
the ns. Temperatures in car trunks have been measured as high as (155˚F) in the summer time. Since the
thermal shut-down point for the Amplier is (158˚F) it is easy to see that it must be mounted for maximum
cooling capability. To achieve the maximum advantage of convection air ow in an enclosed trunk, mount the
amplier in a horizontal position. Cooling requirements are considerably relaxed when mounting inside the
passenger compartment since the driver will not allow temperatures to reach a critical point. Floor mounting
under the seat is usually satisfactory as long as there is at least 1 inch (2.54cm) above the Amplier’s ns for
ventilation.
a. Select a sutable location that is convenient for mounting, accessible for wiring and has
ample room for air circulation and cooling.
b. Use the amplier as a template to mark the mounting holes. Remove the amplier and
drill holes. Use extreme caution. Inspect underneath the surfaces before drilling!
c. Secure the Amplier using the screws provided.
CAUTION: Before connecting any wires to the amplier, disconnect the ground lead from
the battery. Leave the ground lead disconnected until you are done wiring the
amplier.
