THANK YOU
for purchasing a JBL®Grand Touring®Series
automotive loudspeaker component system. We’ve
organized this manual to make your installation as
simple and trouble-free as possible. Please read it
thoroughly before proceeding. Remember to keep
your sales receipt and this manual in a safe place
so both are available for future reference.
INSTALLATION WARNINGS AND TIPS
ABOUT THESE INSTRUCTIONS
Installation of automotive stereo components
can require extensive experience with a variety of mechanical and electrical procedures.
Although these instructions explain how to
install Grand Touring Series component systems 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 –
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, combined 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:
• Woofers
• Grilles and mounting adapter(s)
(no grille with the GTO8607C)
• Tweeters with surface/flush
I-Mount™(patent no. 5,859,917) kits
• Crossover networks with mounting screws
NOTE: The supplied crossover networks
are designed to work with the above-listed
transducers. Do not substitute 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 window’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.

MOUNTING RINGS
The GTO607C is packaged with two
different speaker adapters. The adapters
will allow the speakers to be installed into
various factory 6," 6-1/2" and 6-3/4" openings.
The metal adapter can be mounted in many
European vehicles, Japanese vehicles or
vehicles with 6" speaker locations. The
plastic adapter can be mounted in many
vehicles using 6-3/4" speaker locations or
three-point mounting frames.

supplied metal adapter. Mounting with the
plastic adapter is similar.

position by sliding the screw in the groove
on the back of the tweeter cup and lock the
tweeter in place using the small retaining
screw. Rotate the entire assembly in the
mounting surface and tighten the large
hand nut.
Figures 7A through 7D. The Starfish
™
tweeter mount is intended to be used
when the tweeter will be installed behind
a factory grille (e.g., replacing the factory
tweeter behind a door panel). The Starfish
will allow you to mount the component
tweeter directly to the panel itself or to the
area behind the panel. The six mounting
tabs can be removed easily to create a
number of custom configurations.
Note: Check screw clearance before
installing. Use glue if clearance is an issue.
Note: Not all possible mounting
configurations are shown.
