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 iow level inputs?
Your Amplifier has been designed to accept either High-Lev el(spea ker output s
from your radio) or 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.
c. Are your compon e n t s m atched? The peak p o w e r r ating of your spea k e r s m ust
be equal or greater than the Amplifier’s They also must be 1 - 8 Ohms impedance.
(This information is 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(depending on location) 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. lt has an ample heat sink for heat dissipation,
and also designed with a thermal shut-down protection circuit, making it reasonably
tolerant of mounting variations. Any configuration which allows moving air to be directed
over the cooling fins will improve heat dissipation dramatically, DO NOT enclose the
amplifier in a small box or cover it so that air cannot fiow 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
vertical surface.
