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 JBL
GTO17T tweeters 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 – 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 hearing, as well
as hinder your ability to hear traffic. 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.
ABOUT THE FILTER
Passive filter design involves precise
circuit design and component selection.
Moreover, a well-designed filter circuit
provides an intended electrical response,
when combined with the electrical proper-
ties of the speaker, to provide a particular
acoustic response. Each enclosed filter
has been optimized to provide a flat
response when used with a JBL GTO17T
tweeter.
Do not use another brand or type of
passive crossover, or connect more than
one tweeter to a crossover. Doing so may
damage the tweeter.
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.
ABOUT PLACEMENT
Figures 1 through 3 show possible speaker
placements, with Figure 1 being more
desirable. We recommend using the kick
panel for mounting to obtain the best
staging and imaging in most vehicles.
