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. If possible, mount the amplifi er in the climate-controlled passenger compartment. 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 ground wire to the
amplifi er. Make the ground wire short, 24” (60cm) or less, and connect it to a paint-and-corrosion-free, solid,
metal area of the vehicle’s chassis. Adding an additional ground wire of this same gauge (or larger) between the
battery’s negative post and the vehicle chassis is recommended.

The KX amplifi er has dual input sensitivity differential RCA inputs which will receive either high or low level signals
from your car 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 KX
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”. 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.

Install a fuse within 18” (45cm) of the battery and in-line with the power cable 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 KX series offers three different automatic turn-on modes that can be
selected on the end panel; +12V, DC Offset, and Audio. Using either the DC Offset or Audio mode causes the
REM terminal 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 your source unit. Run 18
gauge wire from the Remote Turn-On Lead on your source unit to the terminal labeled REM between the
amplifi er’s positive and negative power terminals. 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.

• Signal Sense Turn-On: The Audio setting is the fi nal alternative for Automatic turn-on. This is a Signal Sense
turn-on method that detects the incoming audio signal from your source unit and automatically turns on the
amp. This turn-on method will not work properly if the input gain control is not set appropriately.

Input Level: The RCA inputs on KICKER KX 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 press in the
Input Level switch on the amplifi er. Refer to the wiring section of this manual for additional instructions.

Fader Switch: Depress the fader switch if you are running two sets of inputs (front and rear for example) to the
amplifi er. Leave the fader switch OFF if you want to drive all channels from a single stereo input.

Sub Input: If there is no dedicated output on your source unit for a subwoofer, use the SUB INPUT switch to set
your subwoofer input to either SUB INPUT or AMP INPUT 2.

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.

KICK EQ Bass Boost Control: The variable bass boost control on the side of the amplifi er is designed to
give you increased output, 0–18dB, at 40 Hz. The setting for this control is subjective. If you turn it up, you must
readjust the input gain control to avoid clipping the amplifi er.

Crossover Switches with Frequency Multiplier: Use the XOVER switches on the end panel of the amplifi er
to set the internal crossovers of AMPS 1 & 2 to OFF, HI-PASS, LO-PASS, or BAND-PASS (AMP 2 only). When
the switch is set to OFF, a full bandwidth signal will be amplifi ed. Set the switch to HP if you want the amplifi er’s
internal crossover to serve as a high-pass fi lter. Set the switch to LP if you want the amplifi er’s internal crossover
to serve as a low-pass fi lter. Set the switch to BP when a specifi c frequency range is required. Never change the
crossover switches with the audio system on!

Set the 1X/10X frequency multiplier switch to the setting that is appropriate for your application. A setting of
10X will set the range of the AMP 1 crossover to 100–5,000Hz, and the LO-PASS crossover of AMP 2 to
400–5,000Hz.

Adjustable Subsonic Filter (SUB): The variable subsonic fi lter will provide a cut-off point for lower frequencies
(10–80Hz) that could potentially damage your speakers from over-excursion, along with wasting your amplifi er’s
power. The setting for this control should be set relative to your speaker’s low-frequency capability.

Remote Bass-KXRC: With the KXRC remote bass level control, you have the ability to control the output level
of the amplifi er remotely. To surface-mount the KXRC remote bass level control, simply screw the remote to the
chosen location, then run the cable from the controller to the “Remote Bass” jack on the amplifi er panel. Do NOT
connect/disconnect while the amplifi er is on. See page 5.

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 Protection
(PRT) LED on the side panel of your KICKER KX series amplifi er. Depending on the state of the amplifi er and the
vehicle’s charging system, the LED will either glow red or be off.

Red (PRT) LED fl ickering with loud music? The red (PRT) LED indicates low battery voltage or an illegal
load. 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.

Red (PRT) 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.

INSTALACIÓN

Montaje: Escoja un lugar estructuralmente sólido para montar el amplifi cador KICKER. Asegúrese de que no
haya nada por detrás de dónde van a entrar los tornillos. Escoja un lugar en que queden por lo menos 4 plg.
(10 cm) de espacio abierto de ventilación alrededor del amplifi cador. Si es posible, monte el amplifi cador en el
compartimiento de pasajeros, con ambiente acondicionado. Haga cuatro agujeros con una broca de 7/64 de
plg. (3 mm) y monte el amplifi cador con los tornillos N° 8 que se suministran.

Cableado: Desconecte la batería del vehículo para evitar cortocircuitos. Luego, conecte un cable de conexión
a tierra al amplifi cador. El cable de conexión a tierra debe ser corto, de 24 plg. (60 cm) o menos, y debe
ir conectado a un punto sólido del chasis del vehículo en que no haya ni pintura ni corrosión. También se
recomienda instalar un cable de conexión a tierra adicional, de este mismo calibre (o de mayor calibre), entre la
terminal negativa de la batería y el chasis del auto.

El amplifi cador KX tiene entradas RCA diferenciales de doble sensibilidad de entrada que reciben señales de
alto nivel o bajo nivel de la unidad fuente del sistema estereofónico del automóvil.La señal se puede llevar al
amplifi cador desde las salidas de altavoz de alto nivel de la unidad fuente. Fije el selector de nivel de entrada del
panel de extremo del amplifi cador en la posición de alto (HI). Engarce y suelde conectores RCA al extremo del
cable de altavoz procedente de las salidas de altavoz de alto nivel de la unidad fuente y conéctelo a las entradas
RCA del panel de extremo del amplifi cador o simplifi car la instalación mediante un ZISL KICKER como se
muestra a continuación. Como alternativa, puede conectar producción de su unidad fuente a las entradas RCA
del amplifi cador KX RCA. Fije el selector de nivel de entrada del panel de extremo del amplifi cador en la posición
de bajo (LO). Mantenga el cable de señal de audio alejado de los arneses de cableado de fábrica y otros cables
de alimentación. Si es necesario cruzar este cableado, crúcelo en un ángulo de 90°.
