INSTALLATION
Supplies and Tools Needed
To install the amplifiers, you will need tools,
supplies and adapters. It is best to make sure
you have everything you need before you start.
Supplies
• Black electrical tape
• Amplifier Installation Kit
Tools
• Cordless drill with assortment of bits
• Flat-head and Phillips screwdrivers
• Wire cutters/strippers
• Crimping tool
• 12-volt test light or digital multimeter
• Wire brush, sandpaper or scraping tool
(ground connection to vehicle should be a
clean, unpainted metal surface)
Disconnect Battery
Disconnect the negative (-) battery cable before
starting the installation. Check the battery
ground (there should be two (2) ground wires
coming from the battery - one going to the
starter mounting bolt or engine block and
another going to the vehicle chassis) and make
sure the battery is grounded to the chassis with
at least a #8 gauge wire. Also check the
alternator connections, making sure they are
tight and free from corrosion, rust or dirt.
Location and Mounting
The amplifier’s compact design allows great
flexibility in mounting. Common mounting
locations include under the front passenger
seat or in the trunk area.
When selecting a location, remember that
amplifiers generate heat. Select a location on a
flat surface away from heat and moisture where
air can circulate around the amplifier.
Place the amplifier in the mounting location and
mark the positions of the holes with a marker,
pen or pencil. Carefully drill the mounting holes
in the marked positions, then use the supplied
mounting screws to securely fasten the
amplifier to the mounting surface.
WARNING: Do not cover the amplifier with
carpets or enclose it behind interior trim
panels, and do not mount the amplifier in an
inverted or upside down configuration. Be
sure the mounting location and the drilling
of pilot holes will not damage any wires,
control cables, fuel lines, fuel tanks,
hydraulic lines or other vehicle systems or
components.
Routing Wires
Proper wiring connections are illustrated on the
following pages. If wiring connections are made
incorrectly, the unit will not operate properly and
could become permanently damaged. Follow
the installation instructions carefully, or have
the amplifier installed by an experienced
technician.
