Pro Tip: To get the best performance from your new KICKER Amplifi er and extend the warranty by 1 year, use
genuine KICKER accessories and wiring.

INSTALLATION

Mounting: Choose a structurally sound location to mount your KICKER amplifi er. Make sure there are no items
behind the area where the screws will be driven. Choose a location that allows at least 4” (10cm) of open
ventilation for the amplifi er. Drill four holes using a 7/64” (3mm) bit and use the supplied #8 screws to mount the
amplifi er.

Wiring: Disconnect the vehicle’s battery to avoid an electrical short. Then, connect the PX harness to the
amplifi er. Connect the ground wire to a paint-and-corrosion-free, solid, metal area of the vehicle’s chassis,
making it no longer than 24” (60cm). Adding an additional ground wire of this same gauge (or larger) between the
battery’s negative post and the vehicle chassis is recommended.

The PX amplifi er has dual input sensitivity differential inputs which will receive either high or low level signals
from your stereo’s source unit. A high-level signal can be run from the source unit’s speaker outputs to the
stereo RCA input on the end panel of the amplifi er using the KICKER ZISL as shown (make sure you set the PX
amplifi er’s input level switch to “HI”). Alternatively, the signal can be delivered to the amplifi er using the low-level
RCA outputs on the source unit. Set the input level switch on the end panel of the amplifi er to “LO”. Either
input method will provide a hi-level signal at the output. Keep the audio signal cable away from factory wiring
harnesses and other power wiring. If you need to cross this wiring, cross it at a 90 degree angle.

Cut the looped red power cable located on the PX harness and install a 10A fuse. Fuse installation should be
within 18” (45cm) of the battery and in-line with the harness’ power cable, which is connected to your amplifi er. If
you ever need to remove the amplifi er from the vehicle after it has been installed, the ground wire should be the
last wire disconnected from the amplifi er--just the opposite as when you installed it.

OPERATION

Automatic Turn-On Selection: The PX series offers two automatic turn-on modes that can be selected on the
end panel; +12V or DC Offset. Using the DC Offset mode causes the REM terminal wire to have +12V out for
turning on additional amplifi ers.

• Remote Turn-On: Set the switch to +12V to use the remote turn-on lead from the PX harness. Run 18
gauge wire from the Remote Turn-On Lead on your source unit to the REM wire on the PX harness. This is
the preferred automatic turn-on method.

• DC Offset Turn-On: If Remote Turn-On is not an option, the next best setting is DC Offset. The DC Offset
mode detects a 6V DC offset from the HI-Level speaker outputs when the source unit has been turned on.

Input Level: The RCA inputs on KICKER PX amplifi ers are capable of receiving either Hi or Low-level signals
from your source unit. If the only output available from your source unit is a Hi-Level signal, simply set the Input
Level switch on the amplifi er to HI.

Crossover Switches: Use the HI-PASS switch on the end panel of the amplifi er to set the internal crossover to
OFF or ON. When the switch is set to OFF, a full bandwidth signal will be amplifi ed. Set the switch to ON if you
want the amplifi er’s internal crossover to serve as a high-pass fi lter. Choose a cutoff of 100Hz or 250Hz with the
crossover selection switch. Never change the crossover “OFF/ON” switch with the audio system on!

Input Gain Control: The input gain control is not a volume control. It matches the output of the source unit to
the input level of the amplifi er. Turn the source unit up to about 3/4 volume (if the source unit goes to 30, turn it
to 25). Next, slowly turn (clockwise) the gain on the amplifi er up until you can hear audible distortion, then turn it
down a little.

TROUBLESHOOTING

If your amplifi er does not appear to be working, check the obvious things fi rst such as blown fuses, poor or
incorrect wiring connections, incorrect setting of crossover switch and gain controls, etc. There is a Power
Protection LED on the side power panel of your Kicker PX series amplifi er. Depending on the state of the amplifi er
and the vehicle’s charging system, the LED will glow either Red or Blue. When the blue LED is lit this indicates
the amplifi er is turned on and no trouble exists.

Blue LED off, no output? With a Volt Ohm Meter (VOM) check the following: +12 volt power terminal
(should read +12V to +16V) Remote turn-on terminal (should read +12V to +16V) Check for reversed
power and ground connections Ground terminal, for proper conductivity.

Blue LED on, no output? Check the following: RCA connections Test speaker outputs with a “known”
good speaker. Substitute source unit with a “known” good source unit. Check for a signal in the RCA
cable feeding the amplifi er with the VOM meter set to measure “AC” voltage.

Protection LED fl ashing with loud music? The red LED indicates low battery voltage. Check all the
connections in your vehicle’s charging system. It may be necessary to replace or charge your vehicle’s battery or
replace your vehicle’s alternator.

Protection LED on, no output? Amplifi er is very hot = thermal protection is engaged. Test for proper
impedance at the speaker terminals with a VOM meter (see the diagrams in this manual for minimum
recommended impedance and multiple speaker wiring suggestions). Also check for adequate airfl ow around
the amplifi er. Amplifi er shuts down only while vehicle is running = voltage protection circuitry is engaged.
Voltage to the amplifi er is not within the 10–16 volt operating range. Have the vehicle’s charging and electrical
system inspected. Amplifi er will only play at low volume levels = short circuit protection is engaged. Check
for speaker wires shorted to each other or to the vehicle chassis. Check for damaged speakers or speaker(s)
operating below the minimum recommended impedance.

No or low output? Check the balance control on source unit Check the RCA (or speaker input) and
speaker output connections.

Alternator noise-whining sound with engine’s RPM? Check for damaged RCA (or speaker input) cable

Check the routing of RCA (or speaker input) cable Check the source unit for proper grounding Check



the gain settings and turn them down if they are set too high.

Reduced bass response? Reverse a speaker connection from positive to negative on the stereo/subwoofer
channel(s); if the bass improves, the speaker was out of phase.

Ground Noise? KICKER amplifi ers are engineered to be fully compatible with all manufacturers’ head units.
Some head units may require additional grounding to prevent noise from entering the audio signal. If you are
experiencing this problem with your head unit, in most cases running a ground wire from the RCA outputs on the
head unit to the chassis will remedy this issue.

CAUTION: When jump starting the vehicle, be sure that connections made with jumper cables are correct.
Improper connections can result in blown amplifi er fuses as well as the failure of other critical systems in the
vehicle.

Consejo Pro: para obtener el mejor desempeño de su nuevo amplifi cador KICKER y extender el periodo de
garantía en 1 año, use accesorios y cables genuinos KICKER.

INSTALACIÓN

Montaje: escoja un lugar de estructura sólida para montar su amplifi cador KICKER. Asegúrese que no haya
objetos detrás del área donde se insertarán los tornillos. Escoja un lugar que permita al menos 4” (10cm) de
ventilación abierta para el amplifi cador. Haga cuatro agujeros usando una broca de 7/64” (3mm) y use los
tornillos de #8 suministrados para montar el amplifi cador.

Cableado: desconecte la batería del vehículo para evitar un corto eléctrico. Luego, conecte el arnés PX al
amplifi cador. Conecte el cable de conexión a tierra a un punto metálico limpio y libre de pintura y corrosión, en el
chasis del vehículo, que no sea mayor a 24” (60cm) de largo. Se recomienda agregar un cable a tierra adicional
del mismo calibre (o mayor) entre el poste negativo de la batería y el chasis del vehículo.
