THANK YOU
for choosing a JBL
®
GTi Series subwoofer.
GTi subwoofers are designed to
provide maximum sound output in a
variety of enclosure types while
maintaining the superb sound quality
associated with JBL. To ensure the best
subwoofer performance, we strongly
recommend that installation be entrusted to a
qualified professional. Although these instructions
explain how to install a GTi Series subwoofer in
a general sense, they don’t show the specific
installation procedures that may be required for
your particular vehicle. If you feel you don’t have
the necessary tools or experience, don’t attempt
the installation yourself; rather, ask your authorized
JBL dealer about professional-installation options.
