INSTALLATION AND WIRING

IMPORTANT: Disconnect the vehicle's negative (–) battery
terminal before beginning the installation.
• Wear protective eyewear when using tools.
• Choose a safe mounting location. Check clearances on both sides
of the location. Be sure that screws will not puncture brake or fuel
lines or wiring harnesses, and that wire routing will not interfere with
vehicle operation. Use caution when drilling or cutting.
• When making electrical connections, make sure they are secure
and properly insulated.
• Do not mount the amplifier with the heat sink facing downward, as
this interferes with cooling.
• Using the amplifier as a template, mark the locations of the holes
on the mounting surface.
• Drill pilot holes in the mounting surface.
• Attach the amplifier to the mounting surface with sheet metal
screws (not included).

POWER AND GROUND CONNECTIONS

• Power: Connect the +12V power wire to the positive terminal
of the vehicle's battery. Make sure the fuse and fuse holder are
within 18" (457mm) of the battery.
• Ground: Connect the GND wire to the negative terminal of the
vehicle's battery, or to the vehicle's chassis near the battery with
a screw. NOTE: If possible, remove any paint from the chassis for
best contact. It's recommended to use a star washer below the
ring connector for a secure connection.
• Remote: Connect the remote turn-on wire to the "Remote Out"
lead of the source unit, if using low-level signal inputs with an
aftermarket stereo.NOTE: If you're using high-level signal inputs
(your vehicle's speaker wires), the Apex amplifier's 12-volt DC
offset feature will turn the amplifier on when it senses audio signal.
In this case, you will not have to connect the remote turn-on wire
and can tape or cap it off to prevent the introduction of noise.
