JBL GTO6425 - Manual (Page 2)

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
GTO Series multi-element speakers
in a general sense, they do not show
the exact installation methods for
your particular vehicle. If you feel
you do not 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 permanently damage your hear-
ing, as well as hinder your ability to
hear traffic. The maximum volume
levels achievable with JBL speakers,
combined with high power amplifica-
tion, 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 dam-
age 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 Crossover
Each GTO Series multi-element
speaker includes a built-in crossover
network and requires no additional
external circuits for proper operation.
To insure correct polarity connections,
each speaker is also equipped with
keyed terminals (see Figure 4 on
page 3).
General Care
The loudspeaker grilles may be
cleaned with a damp cloth. Do not
use any cleaners or solvents on the
grilles or the speaker cones.
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.
