Thank you
for purchasing JBL’s
Grand Touring Series multielement auto-
motive loudspeakers. In order that we
may better serve you should you require
warranty service on your new speakers,
please retain your original purchase
receipt and return the enclosed warranty
registration card.
Important: Installation of automotive
stereo components can require exten-
sive experience in performing a variety
of mechanical and electrical procedures.
Although these instructions explain in a
general sense how to install GT Series
loudspeakers, they may not show the
exact installation methods for your par-
ticular vehicle. If you feel you lack the
necessary tools or experience, ask your
authorized JBL car-audio dealer about
professional installation options.
Installation Warnings  and Tips
• Always wear protective eyewear 
when using tools.
• Turn off all audio systems and other
electrical devices before you start. 
Disconnect the (–) negative lead from
your vehicle’s battery.
• Keep speakers in their package(s) until
final installation. When moving a speaker,
always rest it with the cone or dome 
facing up. Never use force to install any
• 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.
Caution: In some cars, fuel tanks may 
be located directly beneath the rear 
deck. Check for adequate speaker-basket
clearance before considering this 
• 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 in both
closed and open positions and verify 
that a mounted speaker will not interfere
with the window crank or with the 
power-window mechanism. 
• If mounting speakers elsewhere, check
for clearance around rear-deck torsion 
bars, glove box or other structural 
• Do not mount speakers where they 
will get wet.
Warning: Playing loud music in an 
automobile can permanently damage
your hearing as well as hinder your 
ability to hear traffic. We recommend 
listening at low levels while in your car.
JBL accepts no liability for hearing loss,
bodily injury or property damage result-
ing from use or misuse of this product.
