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 adequate space is left, and cooling requirements are met.
B. Should you use high or low inputs?
Your Amplifier has been designed to accept either Low-Level (Pre-Amp outputs
from your radio) signal source.
If your radio / source is equipped with Pre-Amp outputs, it is possible to utilize
them to drive the Amplifier and connecting (Amplifier) 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
C. Are your components matched? The peak power rating of your speakers must
be equal or greater than the Amplifiers. They also must be 2-8 Ohms impedance
(This information os normally printed on the speaker magnet).
D. 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 AMPLIFIER
The mounting position of your Amplifier will have a great effect on its ability to
dissipate the heat generated during normal operation. It has an ample heat sink
for heat dissipation, and also designed with a thermal shut-down (for heat
protection)circuit, making air to be directed over the cooling fins will improve
heat dissipation dramatically. DO NOT enclose the amplifier in a small box of
cover it so that air cannot flow around fins.
Temperatures in car trunks have been measured as high as 175'F (80'c) in the
summer time, since the thermal shut-down point for the Amplifier is 185'F (85'c)
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 vertical position, on a vertical surface.
Cooling requirements are considerably relaxed when mounting inside the passenger
compartment since the driver will not often 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 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 4 holes, use extreme caution, inspect underneath surface
before drilling.
c. Secure the Amplifier using the screws provided.
PRE-AMP (LOW LEVEL) OUTPUTS.
