Owner’
s Manual
Thank you
for purchasing a JBL Grand
Touring 2-way Component System. We’ve
organized this manual to make your
installation as simple and trouble-free as
possible. Please read through it complete-
ly before proceeding. If, after having read
it, you decide that you would rather leave
installation to a professional, consult your
JBL Grand Touring Dealer.
Autosound at Its Best
Your JBL Component System is built to
meet the same rigorous standards of con-
struction and performance that have long
established JBL’s renowned home and
professional speaker systems. 
Your Component System has been
designed using a combination of tech-
nologies that bring high value to high per-
formance. The tweeter dome used in 
your Component System tweeter is man-
ufactured from a proprietary material
known as Titanium Composite. This mate-
rial combines the control and damping of
an advanced polymer with the reinforcing
stiffness of vapor-deposited titanium to
prevent breakup at high levels. 
Similarly, the woofer cones are manufac-
tured with a proprietary copolymer which
is reinforced with graphite in order to
deliver the clarity and effortless power
that have made JBL famous. The pattern
molded into this material further stiffens
it, reducing breakup at high listening lev-
els. This cone is suspended by a heavy
Butyl rubber surround, which serves to
absorb any remaining cone resonances
for the clearest, most articulate reproduc-
tion of voices and other mid-range
sounds. As a bonus, the Butyl rubber sur-
round is impervious to temperature
extremes and humidity, making it ideal
for automotive applications. 
By following the installation recommen-
dations and suggestions included in this
manual, you will be assured of many
years of trouble-free enjoyment from your
Grand Touring series loudspeakers.
Component System Parts
Your new Component System consists of
the GTO4 neodymium magnet tweeter
and either a 5-1/4", or 6-1/2" midwoofer.
Both the GTO4 and the midwoofer have
high-quality passive crossover parts
already built into them. Figure 2 is an
illustration of the proper wiring procedure
of the Component System.
Important Paperwork
Before proceeding, be sure to put the
sales receipt from your JBL Component
System purchase in a safe place. It is nec-
essary to validate your Limited Warranty.
Having access to the receipt is also valu-
able for insurance purposes and when it
comes time to resell your vehicle. 
Tweeter Installation
The GTO4 has been supplied with both
Angle and Flush mounting brackets.
Figures 1 and 2 show the proper way to
flush- and angle-mount the GTO4. The
mounting hole diameter for the flush-
mount frame is 39 mm.

Tweeter Output Level
The GTO4 is a very efficient tweeter. If
there is a need to lower the tweeter out-
put level, a pair of 4 ohm / 5 watt resistors
can be connected in series with the 
GTO4 as shown in Figure 3.
To avoid short circuits, make sure that
heat-shrink tubing or electrical tape is
used to cover all exposed wiring.
The in-line crossover acts as a high-pass
filter as well as a protection device that
keeps the tweeter from being over-exert-
ed by low frequencies that it was not
designed to reproduce. Under normal cir-
cumstances this crossover should not be
bypassed or removed for any reason.
Bypass the installed capacitor only when
using an outboard active crossover or a
custom-built passive crossover set above
5kHz.

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 statements
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 wide apart as pos-
sible.
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 GTO4 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 crossover point.
Choosing mounting locations which satis-
fy all of the above criteria will provide the
most satisfying performance.

System Design
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
output of a head unit or an amplifier
(Figures 7 and 8).
If you want to build your system using
active (electronic) crossovers, with sepa-
rate amplifiers to drive the tweeter and
midwoofers, you can bypass the capaci-
tor on the tweeter and the coil on the
midwoofer (Figure 9).
A more advanced system design can be
achieved by adding a GT, GTX, 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 frequencies blocked by
electrical means. Active or passive cross-
overs can be used in order to achieve the
best system fidelity and widest dynamic
range. Crossover frequency recommen-
dations are given in the Specifications.
