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 GTi component
systems in a general sense, they do not
show the exact installation methods for
your particular vehicle. If you do not feel
you 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
hinder your ability to hear traffic, as well
as permanently damage your hearing. 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.
A NOTE ABOUT SYSTEM
PERFORMANCE
For the best performance possible, the
GTi components should be used with a
two-channel amplifier with output power
of at least 50W RMS per channel. The
passive crossover contains impedancecompensating circuitry and has been
computer-optimized for the flattest
possible frequency response with the
tweeter flush-mounted, on-axis with
the listener. The combined responses
of the speakers and passive crossover
constitute a 4th-order Linkwitz-Reily
acoustic alignment and cannot be
duplicated with any electronic crossover
currently available for car audio use.
Consequently, bi-amping a GTi component
system with an electronic crossover is not
recommended.
SPEAKER PLACEMENT
Figures 1– 4 show possible speaker
placements in the order of most desirable
to least desirable. Kick-panel mounting
will provide the best staging and imaging
in most vehicles.
