400 GTi - JBL Car Audio User Guide / Operation Manual. Page 3

Thank you for purchasing the finest

automotive woofer/midrange JBL has ever
produced. As a GTi Competition Series
owner, you are a member of a select group
of people who enjoy the most advanced
mobile audio products available. We call
this group “Club GTi.” By sending in the
customer information card, which you will
find attached to your warranty, we will
automatically register you as a Club GTi
member which will give you access to
exclusive Club GTi apparel and other
special offers we will make available from
time to time. We suggest you fill the card
out at your earliest convenience.

Also, be sure to save your sales

receipt in a safe place. It will be necessary
to use this document as proof of purchase
in the event that you ever need warranty
service. It is also useful for insurance
purposes and for establishing value when
you re-sell your vehicle.

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 400 and 500GTi Midranges.

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
400 or 500GTi in typical installations.
Consult your JBL dealer, or a qualified
technician, for more information.
