About This Manual
Because of the performance capability
of your GTi Competition Series product,
and the variety of potential system
configurations, we strongly recommend
that you have the system professionally
installed. You will also get a better warranty
if your equipment is professionally installed
by an authorized GTi dealer and you have
your warranty card stamped. This manual
provides information on installation and
usage to help a skilled technician get the
most from your GTi Competition Series
product. This manual does not cover basic
information about installation which is
common knowledge to a professional
installer, except for information which is
unique to the 404 and 504GTi systems.
If you feel you possess the necessary
skills, and prefer to install the equipment
yourself, this manual will provide you with
the necessary specifics to properly use the
404 or 504GTi in typical installations.
Consult your JBL dealer, or a qualified
technician, for more information.
Autosound at its Best
The 404 and 504GTi Coupled
Components
TM
are built to meet the same
rigorous standards of construction and
performance that have long established
JBL’s renowned home and professional
speaker systems. Coupled Components
TM
are the first to provide true component
driver quality in a format which mounts
in a single hole. The GTi Coupled
Components
TM
combine the reference
standard 400 and 500GTi Woofer/Midrange
Drivers with a cantilever mounted 20mm
Pure Titanium tweeter and outboard
2-way crossover. The tweeter is mounted
at a 15° angle which, combined with the
exclusive Intermount
TM
mounting system,
allows orientation of the speaker for
optimum imaging in any vehicle. The
near-coincident mounting provides the
considerable advantages of equal sound-
path length from the woofer and tweeter to
your ear, but without the horn loading
effects that create a distorted midrange in
designs with apex-mounted tweeters.
