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 amplier with the heat sink facing downward, as
this interferes with cooling.
• Using the amplier as a template, mark the locations of the holes
on the mounting surface.
• Drill pilot holes in the mounting surface.
• Attach the amplier 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 amplier’s 12-volt DC
oset feature will turn the amplier 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 o to prevent the introduction of noise.

Power/Protect indicators
The power light will illuminate in green when the amplier is getting
power and playing. The light will illuminate in red if the amp enters
protect mode in the event of conditions such as over/under voltage,
short circuit, amplier output circuit failure, or excessive heat.

SIGNAL INPUT
• Line-level inputs: If your source unit oers preamp outputs,
connect to the amplier’s L and R preamp inputs using RCA patch
cables.
• High-level inputs: If your audio system’s source unit does not
have line-level outputs, use the supplied high-level input adapters
to connect to either the front or the rear speaker output wires of
your source unit. Use solder, butt connectors, or your preferred
splicing method. The 12-volt DC oset feature will turn the
amplier on when it senses signal.
• Input level selection: If you’re sending signal to the amplier
using low-level outputs from your source unit, slide the input level
selector to “LO.” If using high-level outputs from your source unit,
slide the selector to “HI.”

SPEAKER OUTPUT CONNECTIONS
Connect your speakers to the amplier’s speaker output wires,
observing proper polarity: connect each amplier’s positive (+) lead
to the appropriate positive (+) speaker terminal, and negative (-) lead
to the appropriate negative (-) speaker terminal. NOTE: Speaker-wire
extensions might be necessary.
• PA454 4-channel operation: Connect the front left speaker leads
(white and white/black) to the front left speaker’s + and - terminals,
and the front right speaker leads (gray and gray/black) to the
