Warnings and Tips
Installation Precautions
Before beginning the installation of the
amplifier read the following points
carefully. Failure to heed these warnings
could result in personal injury or damage
to property.
• The unit should be installed only in
vehicles that have 12-volt negative
ground electrical systems. Connection to
other types of electrical systems may
damage the amplifier and/or the vehicle’s
electrical system.
• Before beginning the installation,
disconnect 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 vehicle’s radio
features a code-type security system,
make certain you know the code before
disconnecting the battery!
• Work in an area that is well-ventilated.
• Wear eye protection whenever cutting,
drilling or filing any parts of the vehicle.
• Wear ear protection when using high-
speed drills, saws, sanders, or grinders.

• 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 damaged while doing
so. Such components may be hidden
within double-walled panels or structural
members of the vehicle, so be extremely
cautious.
• Do not bypass or modify the fuses on
the chassis of the amplifier. Do not
replace a fuse with one rated for higher
current levels. Doing so could result in
damage to the amplifier or to the
vehicle’s electrical system. Repeated
blowing of the power supply fuse
indicates a problem within the amplifier
or improper installation.
• An additional power supply fuse (not
included) must be located as close as
possible to the battery on the +12V wire
to minimize the chance of electrical
system damage or fire. Do not ignore this
precaution! If the heavy gauge power
wire required with the GTQ amplifier ever
becomes shorted to ground, the wire will
get extremely hot, causing the insulation
to burn off and will likely cause a fire if
not properly fused.
