Owner’s Manual

Thank you for purchasing JBL’s
Grand Touring Series multielement automotive 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 extensive 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 particular 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
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.
Caution: In some cars, fuel tanks may
be located directly beneath the rear
deck. Check for adequate speaker-basket
clearance before considering this
location!
• 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
elements.
• 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 resulting from use or misuse of this product.

mounting ears must be removed.
