PLANNING YOUR CAR AUDIO SYSTEM
It is important that you decide what you are trying
to achieve. Car audio systems can vary from merely
upgrading your existing factory installation to multi¬
amplifier systems that include equalizers, bridging
modules, crossover modules, low pass filters, high pass
filters, and a variety of speakers. This section contains
the simple approaches to audio system design to the
very complex. By studying the diagrams, you will see
that you can start with a relatively simple system that
can gradually grow by adding accessories and additional
amplifiers.
A. USING EXISTING 6 X 9 SPEAKERS
If you want a good performance system without having
to install special speakers in your car, a single 220 gx,
240gx, or GS-100 amplifier will do an excellent job for
you. A basic single amplifier system is shown in figure 1.

(1) Adding Equalization. To improve the system even
more, you could add an equalizer, such as an
ORION 300 PRQ Pre Amp Equalizer, 600 EQM
Equalizer, or 500 PMQ Parametric Equalizer (see
page 8). The equalizer would be inserted in the
system between the deck and the amplifier as
shown in figure 2.
(2) Front and Rear Speakers. If your car is equipped
with front and rear speakers, you will want to use
a separate amplifier for each pair of speakers as
shown in figure 3.
