Component Placement  
Because of the JBL Component System’s  
small size and extremely versatile mount-  
ing options, there are an almost infinite  
number of placement options to achieve  
excellent sound quality in any vehicle.  
Please consider the following state-  
ments to help you get the most from  
your system.  
1. The most spacious stereo image is  
achieved when the left and right  
speaker systems are placed as far apart  
as possible.

Right  
Figure 6  
2. The best center image will be achieved  
when the distance from the left speaker  
and the right speakers are as equal as  
possible from your listening position.  
This is most easily achieved by placing  
the speakers as far forward as possible.  
3. Treble is directional in nature. This  
means that high frequencies are reduced  
as you move off the tweeter's axis. The  
angle mounts will allow the tweeters to  
be pointed across the car to the listener  
on the opposite side. This will make each  
listener slightly off-axis to the tweeter that  
is closest to that listener, which helps to  
compensate for the fact that the listener is  
always closer to one tweeter than to the  
other (see Figure 6).  
The best system integration is achieved  
when the tweeter is mounted close to the  
midwoofer speaker. This helps smooth  
the transition from the midrange and  
tweeter at the crossover point.  
Choosing mounting locations that satisfy  
all of the above criteria will provide the  
most satisfying performance.

There are a variety of system options  
available with the Component System.  
The simplest configuration is to use them  
full range with their built-in passive  
crossovers by connecting them to the out-  
put of a head unit or an amplifier (Figures  
7 and 8).

A more advanced system design can be  
achieved by adding a Decade,™ GT,  
Power, GTi, or equivalent subwoofer  
to your component system. In this case  
the component system will be used as  
high and midbass frequency drivers and  
should have their extremely low frequen-  
cies blocked by electrical means. Active or  
passive crossovers can be used in order  
to achieve the best system fidelity and  
widest dynamic range. Crossover fre-  
quency recommendations are given in  
the Specifications.

A Note on Power Handling  
As a result of their high efficiency, all JBL  
loudspeakers will produce reasonable vol-  
ume levels in the automotive environ-  
ment using very little amplifier power.  
However, the use of a small amplifier to  
attain very high volume levels could lead  
to over-driving the amplifier. This will  
generate high distortion levels which can  
easily damage loudspeakers, even if the  
rated power of the amplifier is below the  
rated maximum power handling of the  
loudspeaker!  
As a general rule, do not turn up the vol-  
ume control past the point where you  
hear distortion in the form of either signal  
distortion from an overdriven amplifier or  
mechanical noise from an overstressed  
speaker.  
Installation Warnings  
and Tips  
• Be careful not to cut or drill into fuel  
tanks, fuel lines, brake or hydraulic lines,  
vacuum lines or electrical wiring when  
working on your vehicle. Inspect behind  
panels before you cut or drill.  
• Make sure that the midwoofer will  
physically fit in the mounting location. If  
door mounting, check for adequate  
clearance with the window in both  
rolled-up and rolled-down positions as  
well as for interference with window  
crank and power window mechanism.  
If mounting elsewhere, check for  
clearance around rear deck torsion bars,  
glove box or other structural elements.  
• Do not mount speakers where water  
may splash on the cones.  
• Make sure that it will be easy to run  
connecting wires to the speakers. Trace  
speaker wire paths before you undertake  
mounting.  
• Always disconnect the ground wire  
from the battery before doing any work  
on the vehicle.  
For the best performance and system reli-  
ability, you should select an amplifier  
with an output rating greater than the  
maximum power likely to be used to gen-  
erate the desired volume levels.  
If you want your system “Loud + Clear,”  
we suggest that you step up to a JBL  
power amplifier which has an RMS power  
rating equal to, but not exceeding the  
Maximum Recommended Amplifier  
Power listed in the specifications of your  
specific JBL speaker. This margin of  
reserve power will ensure that the ampli-  
fier will not attempt to deliver more  
power than its design allows. Your dealer  
will be happy to point out which high  
power JBL amplifiers are optimum for  
your application and listening habits.  
Following these guidelines will provide  
virtually distortion-free sound reproduc-  
tion and long loudspeaker life.  
WARNING: Playing loud music over  
120dB can permanently damage your  
hearing. The maximum volume levels  
achievable with JBL components and  
high power amplification may exceed  
safe levels for extended listening.  
When listening at high volume levels,  
always use hearing protection or turn  
the volume down!  
CAUTION: Fuel tanks are located  
directly beneath the rear deck in  
some cars. Check for adequate speaker  
basket clearance before considering this  
location!
