Once you have run both the power and ground wires, it's time to connect the
cables to the amplifier. Cut off excess wire and, using wire strippers, strip the ends
of the power and ground cables approximately 1/4 inch. Locate the

power and ground connector (supplied). With a small flat bladed screw driver,
loosen the screws before attempting to insert the cables. Insert the wires into the
appropriate hole, and tighten the screws. Check for stray strands of wire which
may short out. Once the wires are secure, the
Power
Lock™
may be plugged into
the amplifier. The Power/Ground
Power
Lock™
will accommodate 4 gauge wire
for the
PCX 2125, PCX 2200
and
PCX 2400.

Both excessive temperature and low impedance (or short circuit) conditions will
activate the amplifier's
A M - V
protection circuitry, which turns down the amplifier's
output. When the amplifier cools down, or the impedance is corrected, the
A M - V
will restore full power. If your amp is turning down, check your speakers and wiring
for low impedance and short circuits. Also, ensure that there is nothing blocking
the normal convective airflow of the amplifier. No obstruction should be within 2"
of the amplifier on all sides.
NOTE: Low battery voltage will cause the amplifier to run warmer and
possibly damage the amplifier.

Short Circuit Protection engaged: The amplifier will turn off and try to come
back on immediately. The amplifier will cycle like this indefinitely, with "blips" of
sound each time. If this is the case, check your speakers and wiring for low
impedance and short circuits.
Thermal Protection engaged: The amplifier will turn off and several minutes
later will come back on. In this case, ensure that there is nothing blocking the
normal convective airflow of the amplifier. No obstruction should be within 2" of
the amplifier on all sides.
NOTE: Low battery voltage will cause the amplifier to run warmer and
possibly damage the amplifier.
