Mounting Positions
Place the amplifier in the installation
location. Use a pen or pencil to mark the
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 upholstery, 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 holes on its side with the
holes previously drilled. Put washers on
the sheet metal screws provided and
drive them into the mounting panel.
Tighten the screws evenly until the unit is
securely mounted.

Wiring
Proper wiring of the GTQ amplifier 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
specific type of wire is required for a
certain application, it will be noted.
Route the wiring through the car
carefully. 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
grommets 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.

Power Supply Connections
The power input and remote turn-on
wires are connected to the GTQ amplifier
via the power connector on the end of
the amplifier.
wires are connected to the GTQ amplifier
via the power connector on the end of
the amplifier.
+12V Battery Wire
• Connect a wire directly from the +12
volt terminal of the battery to the +
Battery terminal on the amplifier. Use a
minimum of AWG #10 for the GTQ190.
Use wire that is heat- and oil-resistant
whenever running wires through the
engine compartment. All wire-to-wire
connections should be soldered and
insulated with heatshrink tubing, or
connected through a high-quality
insulated crimp-on connector or secure
set-screw-type terminal blocks. Never
leave bare wire exposed. Terminate wires
with crimp or solder-on lug terminals
whenever appropriate.
• GTQ amplifiers will draw large amounts
of current from the vehicle’s electrical
system, enough to overload conventional
vehicle wiring. Therefore the +12 volt
power supply must be taken directly from
the positive side of the battery. Do not
connect to the vehicle’s fuse block or to a
wire feeding other accessories.
• To prevent electrical system damage or
fire, a fuseholder and fuse (not included –
30 amps) must be installed in the power
supply wire as close to the battery as
possible, and before the wire travels
through the firewall or other metal panel.
