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 completely
before proceeding. If, after 
having read it, you decide that
you would rather leave installa-
tion 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 construction and
performance that have long
established JBL’s renowned
home and professional speaker
systems. 
Your Component System has
been designed using a combina-
tion of technologies that bring
high value to high performance.
The tweeter dome used in 
your Component System tweeter
is manufactured from a 
proprietary material known as
Titanium Composite. This 
material 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
manufactured 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 listen-
ing levels. This cone is sus-
pended by a heavy Butyl rubber
surround, which serves to absorb
any remaining cone resonances
for the clearest, most articulate
reproduction of voices and other
mid-range sounds. As a bonus,
the Butyl rubber surround is
impervious to temperature
extremes and humidity, 
making it ideal for automotive
applications. 
By following the installation rec-
ommendations 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 GTC04 neodymium
magnet tweeter and either a 4",
5-1/4", or 6-1/2" midwoofer. Both
the GTC04 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 necessary to vali-
date your Limited Warranty.
Having access to the receipt is
also valuable for insurance pur-
poses and when it comes time to
resell your vehicle. 
Tweeter Installation
The GTC04 has been supplied
with both Angle and Flush
mounting brackets. Figures 1 and
2 show the proper way to flush-
and angle-mount the GTC04. The
mounting hole diameter for the
flush-mount frame is 1-3/4".
