(3) Adding Subwoofers. For added punch, you could
add a couple of subwoofers to the system as shown
in figure 4. This will give you the most coherent
and natural sound. In this system, a pair of mid¬
range/tweeter speakers are located in the front
(usually in the top of the dash), and a midrange/
tweeter speaker is located in each rear door or side
panel. The subwoofers are installed in the rear.
This does not mean that the passengers seated in
the rear will be overcome by the bass. Low fre¬
quency sound waves tend to wrap around the in¬
terior such that they are perceived as coming from
all directions.
IMPORTANT NOTE: At this point, you must deter¬
mine if your car has enough power to supply the needs
of the engine, lighting system, and air conditioning
system as well as the audio system. An existing car
electrical system can generally handle up to four 220gx
or 240gx amplifiers, or up to three 280gx or GS-100
amplifiers. If you plan to use more, or larger, amplifiers,
refer to the discussion on "power requirements" on
page 29.
(4) Adding Crossover or Bridging Modules. An existing
speaker system can also include a crossover module
and/or bridging module similar to the custom sys¬
tems described in paragraphs B through F below.
B. USE OF A CROSSOVER MODULE
An ORION 200 CRX Active Crossover or 300 CRX
3-Way Active Crossover can be one of the most im¬
portant additions to your car audio system. It lets
you adjust the highs and midranges to where they
sound best, then independently adjust the lows to
where they sound great. The 200 CRX Active Cross¬
over contains a low pass filter section (for your sub¬
woofers) and a high pass filter section (for midranges
and tweeters). The 300 CRX 3-Way Active Cross¬
over contains a low pass filter section for the sub-
NOTE:
The DIN and RCA input connect¬
ors for all amplifiers are wired in
parallel. This means that when an
input is connected to the DIN
connector, it is also present at the
RCA connectors and the other
way around. This makes it pos¬
sible to connect several amplifiers
in parallel as shown in this figure.
"Phantom power is supplied to
the equalizer by the amplifier
through the DIN cable.
