Installation Precautions
Before beginning the installation of the
amplifier, read the following precautions
carefully. Failure to heed these warn-
ings could result in personal injury or
damage to property.
• The GTS 100 should be installed
only in vehicles that have 12-volt
negative ground electrical systems.
Connection to other types of electri-
cal systems may damage the ampli-
fier and/or the vehicle’s electrical
system.
• 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.
Note: If the vehi-
cle’s radio features a code type secu-
rity system, make certain you know
the code before disconnecting the
battery!
• Work in an area that is well ventilated.
• Wear eye protection whenever cut-
ting, drilling or filing any parts of the
vehicle.
• Wear ear protection when using high
speed drills, saws, sanders, or
grinders. We want you to be able to
enjoy the system once it is installed.
• Before cutting or drilling any holes in
the vehicle, inspect the area carefully
to be sure there are no electrical
wires, hydraulic brake lines, fuel
lines, or fuel tanks that may be dam-
aged while doing so. Such compo-
nents may be hidden within double
walled panels or structural mem-
bers of the vehicle, so be extremely
cautious.
• 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.
Physical Installation
There are several factors to consider
when selecting a mounting location for
the GTS100.
• It must be solidly mounted in a place
where it will not be subjected to
excessive shock and vibration.
• Under no circumstances should the
amplifier be mounted where it will be
exposed to moisture or extreme heat.
• Try to mount the amplifier where the
main +12 volt power supply wire,
which must be connected directly to
the battery, can be kept relatively
short.
