INSTALLATION WARNINGS AND TIPS
ABOUT THESE
INSTRUCTIONS
Installation of automotive stereo com-
ponents can require extensive experi-
ence with a variety of mechanical and
electrical procedures. Although these
instructions explain how to install
Grand Touring Series component sys-
tems in a general sense, they do not
show the exact installation methods
for your particular vehicle. If you do
not feel you have the experience, do
not attempt the installation yourself,
but instead ask your authorized JBL
car audio dealer about professional
installation options.
LOUD MUSIC AND
HEARING
Playing loud music in an automobile
can hinder your ability to hear traffic,
as well as permanently damage your
hearing. The maximum volume levels
achievable with JBL speakers, com-
bined with high power amplification,
may exceed safe levels for extended
listening. We recommend using low
volume levels when driving. JBL
accepts no liability for hearing loss,
bodily injury or property damage
as a result of use or misuse of this
product.
REAR DECK
PRECAUTION
In some cars, fuel tanks may be
located directly beneath the rear
deck. Before installation, make sure
there is adequate speaker basket
clearance before considering this
location!
ABOUT THE CONTENTS
The Grand Touring Series component
system includes:
•5-1⁄4" or 6-1⁄2" or 6" x 8" (5" x 7")
woofer
• Grille and mounting adapter(s)
• 1" tweeter with surface/flush
I-Mount
™
(patent no. 5,859,917) kit
• Crossover network with mounting
screws
NOTE: The supplied crossover net-
work is designed to work with the
above-listed transducers. Do not sub-
stitute another crossover network or
use other speakers when connecting
the system (see Figures 8A and 8B).
INSTALLATION TIPS
• Always wear protective eyewear
when using any tools.
•Turn off all audio components and
other electrical devices before you
start. Disconnect the (–) negative
lead from your vehicle’s battery.
• Keep speakers in their package
until final installation. When moving
a speaker, always rest it with the
cone or dome facing up. Never use
force to install any speaker.
• Check clearances on both sides of
a planned mounting surface before
drilling any holes or installing any
screws. Remember that the screws
can extend behind the surface.
•At the installation sites, locate
and make a note of all fuel lines,
hydraulic brake lines, vacuum lines
and electrical wiring. Use extreme
caution when cutting or drilling in
and around these areas.
• Before drilling or cutting holes, use
a utility knife to remove unwanted
fabric or vinyl, to keep material
from snagging in a drill bit or saw.
• For door installations, check the
clearance with the windows
throughout the range of the win-
dow’s travel, and verify that a
mounted speaker will not interfere
with the window crank or power
window mechanism.
• If mounting speakers elsewhere,
check for clearance around rear
deck torsion bars, glove box or
other structural elements.
• Do not mount speakers where they
will get wet.
• If possible, select a mounting site
for the crossover network that is
near the speakers and provides
easy access for connections.

woofer in a standard 6" opening.
NOTE: The GTO606c uses an
adapter to fit a variety of different
6" openings. Select an appropriate
adapter ring and secure it to the
vehicle using the sheet-metal
screws provided, then attach the
speaker to the ring with the
machine screws.
