Grand Touring Series multi-element
automotive loudspeakers. We’ve
organized this manual to make your
installation as simple and trouble-free
as possible. Please read through it
completely before proceeding. If, after
having read it, you decide that you
would rather leave installation to a
professional, consult your JBL Grand
Touring Dealer.

Autosound at its Best
Your JBL GT series multi-element
speakers are built to meet the same
rigorous standards of construction and
performance that have long established
JBL’s renowned home and professional
speakers.
These speakers incorporate advanced
materials and construction especially
suited to the unique acoustic environment of modern vehicles. They are
engineered to provide excellent
dispersion, wide frequency response,
and high power handling.

Speaker Placement
Aim Triangle of Tweeter Diffuser
Toward Listener
Because of the GT Series speakers’ versatile mounting options, there are many
placement options which will achieve
excellent sound quality in your vehicle.
Please consider the following to help you
get the most from your speakers.
1. The most spacious stereo image is
achieved when the left and right speakers
are placed as wide apart as possible.
2. The best center image will be achieved
when the distance from the left speaker
and the right speaker are as equal as possible from your listening position. This is
most easily achieved by placing the
speakers as far forward as possible.
3. Treble is directional in nature. This
means that high frequencies are reduced
as you move off the tweeter’s axis. If possible, rotate the speakers so that the angle
of the tweeter points across the car to the
listener on the opposite side. This will
make each listener slightly off-axis to the
tweeter that is closest to that listener, but
on axis to the most distant speaker, which
helps compensate for the fact that each
listener is always closer to one speaker
than to the other (see Figures 4a and 4b).
Choosing mounting locations which satisfy all of the above criteria will provide the
most satisfying performance.

System Design
A more advanced system design can be
achieved by adding a GT, GTX, GTi, or
equivalent subwoofer to your GT series
speakers. In this case the GT series multielement speakers will be used as high
and midbass frequency drivers and
should have their extremely low frequencies blocked by electrical means. Active
or passive crossovers can be used in
order to achieve the best system fidelity
and widest dynamic range. A crossover
frequency of between 80Hz and 120Hz is
recommended for the best imaging and
widest dynamic range.
Installation Warnings
and Tips
• Be careful not to cut or drill into fuel
tanks, fuel lines, brake or hydraulic lines,
vacuum lines or electrical wiring when
working on your vehicle. Inspect behind
panels before you cut or drill.
• Make sure that the speaker will
physically fit in the mounting location. If
door mounting, check for adequate clearance with the window in both closed and
open positions as well as for interference
with the window crank and power
window mechanism. If mounting elsewhere, check for clearance around rear
deck torsion bars, glove box or other
structural elements.
• Do not mount speakers where they will
get wet.
• Make sure that it will be easy to run
connecting wires to the speakers. Trace
speaker wire paths before you undertake
mounting.
• Always disconnect the ground wire from
the battery before doing any work on the
vehicle.
CAUTION: Fuel tanks are located directly
beneath the rear deck in some cars. Check
for adequate speaker basket clearance
before considering this location!
A Note on Power Handling
As a result of their high efficiency, all JBL
loudspeakers will produce reasonable
volume levels in the automotive environment using very little amplifier power.
However, the use of a small amplifier to
attain very high volume levels could lead
to overdriving the amplifier. This will
generate high distortion levels which can
easily damage loudspeakers, even if the
rated power of the amplifier is below the
rated maximum power handling of the
loudspeaker!
As a general rule, do not turn up the
volume control past the point where
you hear distortion in the form of either
signal distortion from an overdriven
amplifier or mechanical noise from an
overstressed speaker.
For the best performance and speaker
reliability, you should select an amplifier
with an output rating slightly higher than
the maximum power likely to be used to
generate the desired volume levels. This
margin of reserve power will ensure that
the amplifier will not attempt to deliver
more power than its design allows.
WARNING: Playing loud music over
120dB can permanently damage your
hearing. The maximum volume levels
achievable with JBL speakers combined
with high power amplification may
exceed safe levels for extended listening.
When listening at high volume levels,
always use hearing protection or turn it
down!

Service
Should your loudspeaker ever need service, return it to the JBL dealer from
whom it was purchased. If for some reason this is impractical, call 800-336-4JBL
for your nearest warranty station. Do not
return products to the JBL factory without prior authorization.
