Speaker Connections - JBL GTS100X Owner's Manual

Speaker Connections

When connecting speaker wires,
20
be sure that no uninsulated wire
remains exposed and no loose
strands of wire touch either an
adjoining wire, terminal or
metal surface. Securely crimp or
solder all connections and insu-
late them with heatshrink tubing.
Use high-quality 18 gauge or
larger speaker wire for the
amplifier-to-speaker connections.
Larger wire or special high-
performance speaker cables
may improve the performance
of some systems.
Be very careful when speaker
wire is routed through a door
hinge area to door-mounted
speakers. Use grommets and
strain reliefs wherever necessary
to prevent damage to the wires.
The proper speaker connection
depends on whether the GTS100x
is used bridged or stereo. The
speakers are connected to the
amplifier with the included wire
harness. If you wish to purchase
the raw connector to make a
custom-length harness, the
part number is listed in the
Specifications section. This item
is commonly available from local
electronic parts distributors.
Please do not call JBL for this
part; we stock only the harness
assemblies supplied with the
amplifier.
To get proper bass response and
stereo imaging, all the speakers
in the system must be "in
phase." The input terminals of
the speakers will be marked in
some way to identify positive and
negative polarity. Make sure that
the positive ( ) speaker terminal
+
is attached to the positive ( )
+
amplifier connection in every
speaker-to-amp connection. All
two-conductor speaker wire has
one conductor marked in some
way so it can be easily traced.
The speaker output wire harness
