• The GTS 100 should be installed
only in vehicles that have 12-volt
negative ground electrical systems.

• Before beginning the installation, dis-
connect the negative (ground) cable
from the vehicle’s battery. This will
prevent accidental short circuits while
working on the installation. Reconnect
the cable only after the installation is
complete and the wiring has been
carefully checked to be sure there
are no exposed wires or short circuits
and everything is properly and
securely connected.

• Do not bypass or modify the fuse on
the chassis of the amplifier. Do not
replace the fuse with one rated for
higher current levels. Doing so could
result in damage to the amplifier
and the vehicle’s electrical system.
Repeated blowing of the power
supply fuse indicates a fault within
the amplifier or problems in the
installation.

• An additional power supply fuse (not
included) should be located as close
as possible to the battery on the
+12V wire to minimize the chance of
electrical system damage or fire in
the event of a short circuit in the
power supply wire.

when selecting a mounting location for
the GTS100.

• The GTS100 must be mounted in a
place where air can circulate around
the fins on the chassis. Good air
circulation around the amplifier will
make it operate at lower tempera-
tures and reduce the chance of the
thermal protection circuits being trig-
gered. The installation positions that
provide the most efficient air circula-
tion around the amplifier are shown
below.

• Use a mounting location that allows
access to the wiring connections and
level adjustments. This allows the
unit to be mounted before these con-
nections and adjustments are made.

Controls and Connectors
1. Line Level RCA Inputs – Use these
connectors for line (preamp) level input
to the amplifier. When speaker inputs
are used, this connector can be con-
verted for use as a line-level output by
setting the “Line” switch to “out.”

4. Input Mode Selector – This switch is
used to set the input mode for both pre-
amp and speaker-level inputs. Set this
switch to Stereo for normal operation
using both left and right inputs. Set this
switch to R to drive both the left and
right channels with only a single input
on the right channel. Set this switch to
“L+R” to sum the left and right inputs
for a mono output on both amplifier
channels.

this connector. See the “Audio Input
Connections” section (page 15) for
wiring instructions. This input also
includes JBL’s Common Sense input
circuitry which turns the amplifier on as
soon as a high powered head unit con-
nected to this input is turned on.

switch controls the built in crossover.
Set the switch to “Off” for full band
operation. Set this switch to “Low” to
activate the 80Hz low pass filter on the
amplifier (for subwoofer use). Set the
switch to “High” to activate the 100Hz
high pass filter for use with satellite
speakers. Note that the filter does not
affect the line level outputs on the
amplifier.

Mounting Instructions
Place the amplifier in the installation
location. Use a pen or pencil to mark
the four mounting screw hole locations.
Set the amplifier aside and drill the
holes for the mounting screws. (Note: If
the surface you are mounting the amp
to is covered with carpeting or uphol-
stery, cut a small “x” in the material at
each screw hole location before drilling
the holes. This will help prevent tearing
or stretching of the material and carpet
fibers from being pulled out.) Set the
amplifier in position and align the
mounting holes with the holes previously
drilled. Put washers on the four sheet
metal screws provided and drive them
into the mounting panel. Tighten the
screws evenly until the unit is solidly
mounted.

Wiring
Proper wiring of the GTS100 and the
associated components is extremely
important for proper performance and
long term reliability. Using the proper
type of wire is very important. If a spe-
cific type of wire should be used for a
certain application, it will be noted.
associated components is extremely
important for proper performance and
long term reliability. Using the proper
type of wire is very important. If a spe-
cific type of wire should be used for a
certain application, it will be noted.
All wiring connections should be made
either by soldering with heatshrink tub-
ing insulation or with high quality crimp
type insulated connectors installed with
a good crimping tool. Soldering crimp
connections is recommended to further
enhance connection reliability. Never
use wire-nuts, insulation-displacement
connectors (i.e. ScotchLok type), or
“twist and tape” connections. Do not
use electrical tape; it will loosen with
age and extreme temperatures. Never
leave bare wire exposed.

Route the wiring through the car care-
fully. Do not allow wires to lay against
sharp sheet metal edges or any other
surfaces that might wear away or cut
through the insulation of the wire. Use
insulated strain reliefs, rubber grom-
mets and plastic tubing to protect the
wires whenever they are run through
sheet metal panels or are placed where
they might be pulled or damaged.
