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.

2

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. 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 in the KEY carton and install using the 20A fuse. The fuse 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. The KEY amplifi er is capable of using the wiring directly from your head unit, but for best results it
is recommended you use power and ground wiring from the vehicle’s battery and chassis. KICKER
recommends 14 gauge wire.

If needed, cut off the RCA connections to use hi-level input.

For multiple amplifi er installations where distribution blocks are used, each amplifi er should have its
proper-rated fuse, or breaker, installed between the amplifi er and the distribution block within eighteen
inches of the block, or on the distribution block if it provides for fusing. The primary power wire should
also be fused between the battery and distribution block, within eighteen inches of the battery’s positive
terminal, with a fuse or breaker rated at least to the sum of the individual amplifi er’s fuse values, but
doesn’t exceed the capacity of your wiring.

Automatic Turn-On Selection: The KEY series offers two different automatic turn-on modes that can
be selected on the end panel; +12V and DC Offset. Using the DC Offset mode causes the REM 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 your source unit. Run
18 gauge wire from the Remote Turn-On Lead on your source unit to the blue REM wire on KEY
amplifi er's wiring harness. This is the preferred automatic turn-on method.

• If 12V remote turn-on is not available, DC Offset turn-on can be used if speaker-level audio inputs
are being used. The DC offset mode detects a 3V DC offset on the speaker wires when the source
unit has been turned on.

Radio Detect: The RCA inputs on KICKER KEY amplifi ers are capable of receiving either Hi or Low-level
signals from your source unit. If you are using Hi-Level inputs, but your source unit cannot detect an audio
system present or refuses to play audio out of one or more speakers, you may need to set Radio Detect
to ON. This will activate a load resistor at the amplifi er’s inputs and tell the source unit there are speakers
present. Do NOT use Radio Detect if you are using a Low-Level input signal; doing so will greatly reduce the
input signal.

Input Gain Control with Gain Matching: 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 and features Gain Matching to prevent clipping the
input. For a quick setup, turn the source unit up to about 3/4 volume (if the source unit goes to 30, turn it to

25). KICKER recommends using the test tones at www.KICKER.com/support/ to reach the most accurate
and best performing settings. Next, with gain knobs all the way down, slowly turn (clockwise) the gain up
until you see the LIMITER LED light up or hear audible distortion, then turn it down a little. If the LIMITER’s
LED comes on, the input is still clipping. This step should be performed after KEY Auto Setup and crossover
settings have been applied.

Mic Input: Connect the included microphone to the 3.5mm (1/8”) microphone input and use in conjunction
with the Auto Setup process to automatically set Time Alignment, KICKER EQ, and Output Level Matching.
Install face up to headrest, pointing as straight as possible to the roof.

6

TIME DELAY: Set to enable (EN) for all speaker’s output to reach the driver or microphone location at the

same time. Set to defeat (DF) to turn time delay off.

KICKER EQ: Set to enable (EN) to turn KICKER EQ on (recommended), set to defeat (DF) to turn KICKER
EQ off. When OFF, the frequency response curve will be fl at.

BI-AMP MODE: The majority of systems require this switch to be OFF. Turn ON only if your speakers
are wired in “Bi-Amp” mode (refer to BI-AMP operation picture on page 5). The Bi-Amp mode is to be
specifi cally used without passive crossovers. Possible usages are with component speakers (two woofers
and two tweeters), or with door woofers and dash speakers. Once the Bi-Amp switch is ON, the KEY
amp will automatically detect and apply Bi-Amplifi cation settings during the KEY Auto Setup:

• Woofers and Tweeters: 3.2kHz 24dB/oct High Pass for the tweeters, 3.2 kHz low pass for the
woofers.

• Woofers and Dash Speakers: 320 Hz 24dB/oct High Pass for the dash-speakers, 640 Hz low pass
for the woofers.

COMPRESSION: Set to enable (EN) to turn Auto Compression on, reducing high amplitude signals above
a certain threshold, giving a more consistent listening experience and protecting your audio system. Set to
defeat (DF) to turn Auto Compression off.

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

HI-PASS: Use the HI-PASS switches of the amplifi er to set the internal crossover. Choose a cutoff of
60Hz, 80Hz, 120Hz, or OFF depending on the confi guration of switches.

LIMITER: The LIMITER may engage for multiple reasons, as indicated by the LIMITER LEDs. This is to
protect your speakers and allow for continuous playback. The LIMITER will engage during:

• Engine start: The KEY is a Start-Stop compatible amplifi er; it will not turn off during engine start. When
your vehicle’s engine is starting there is a voltage dip in the +12V line. In order to prevent a clipped
output signal from reaching your speakers, the LIMITER engages during that moment. Should you
be listening at a moderate or higher volume level, you may see the LIMITER indicators light up during
engine start and turn off once the engine is running.

• Low voltage: If the operating voltage fed to the amplifi er is below a level specifi ed for full power
operation (+10.8V), you may see the LIMITER indicators light up at moderate or high music volume
levels.

• Input signal overdrive: When the input signal to the amplifi er causes its output to exceed the maximum
rated power, the LIMTER will engage to prevent severe clipping. This can be caused by the gain setting
or the input signal being too high, or both. Reduce the gain or the strength of the input signal.

The LIMITER engages as the amplifi er reaches and surpasses its maximum operational temperature,
limiting the power of the amplifi er as the temperature rises. Consequently, the temperature will take
longer to rise until an equilibrium is achieved in which the temperature won’t climb any higher, and the
output power won’t be limited any further. This protection does not cutoff the audio abruptly and it does
not output clipped audio to the speakers.

• Compression switch ON: To fully protect your speakers, you may turn the compression switch ON.
This will cause the LIMITER to engage whenever the amplifi er is about to output a clipped audio signal,
though some distortion may still be audible. If the gain is set properly and the audio source doesn’t clip,
this will provide another fail-safe for your audio system while limiting the current draw of the amp, which
lowers the load of the amp on the vehicle's electrical system.

KEY AUTO SETUP

The KEY Activation Button is a multi-function button attached to the
included microphone that will begin the Auto Setup process, toggle
between Auto Setup optimized audio and the original audio once
the Auto Setup process has been completed, or clear previous Auto
Setup settings.

The Auto Setup consists of several tune-up steps including individual speaker equalization, KICKER EQ,
time delay and speaker sensitivity matching. If a setting is defeated with the DIP switches on the KEY
panel, the settings will be registered in memory and can be applied or cleared. Changing the DIP switch
positions does not require a new Auto Setup to be run.

Make sure active noise cancellation and active noise enhanced are disabled beforehand. You will
need to load a source for pink noise from your head unit, whether CD, MP3, AUX, Bluetooth, USB etc.
Uncompressed audio is recommended for best results, as this will ensure full amplitude across the
frequency spectrum (20Hz–20kHz). Visit www.kicker.com/tech to download the pink noise profi le best
suited for your listening habits!

1. Set the KEY amplifi er gains (AMP-1 and AMP-2) to the minimum (fully
counter-clockwise). Place all settings in the signal chain, such as the EQ on
your head unit, to disabled or fl at. Disconnect any speakers or subwoofers
not connected to the KEY amplifi er, factory or aftermarket.

2. Close the car windows, turn off the engine, turn off the HVAC. Install
the microphone to the top of the driver’s side headrest. Make sure the
microphone faces up, pointing as straight as possible to the roof.

3. In most cases, the Bi-Amp switch should be OFF. Check if you need to
turn the Bi-Amp switch ON. Refer to page 6 for more information

4. Start the Pink Noise. Set the Pink Noise volume to a level above
conversational (slightly loud) using your audio source volume control (usually
head-unit).

5. Begin the Auto Setup by quick-pressing the KEY Activation Button. Once initialized, you will hear
repeating tones (beeps), which indicate that you must exit the vehicle and close the door. You will have 10
seconds until the process begins. Beeps and noises during the KEY Auto Setup process can be loud. For

your safety, please do not remain inside the vehicle!

6. Once the Auto Setup has completed, you will hear happy music for a successful setup. You may
quick-press the KEY Activation Button to toggle between the original, non-optimized audio or re-apply the
KEY optimized audio. Dial in the GAIN settings and you're done!

Upon successful completion, if you wish to clear the Auto Setup settings and revert the KEY amp to
“clean”, press and hold the KEY Activation Button for 10 seconds. You will hear a single long beep. You
can then repeat the Auto Setup process if desired.

If the Auto Setup process did not complete successfully, you will hear sad music, followed by beeps
that represent an error code. Count the number of beeps, ranging from 1 to 6, and refer to the
Troubleshooting section. Once you’ve addressed the cause, you can quick-press the KEY Activation
Button to run the Auto Setup process again.

AUTO SETUP FAQ:

Q: How silent must the ambient noise be in order for the Auto Setup work properly?
A: As silent as possible, both inside and outside the vehicle. The HVAC should be off and the windows rolled up,
with as few obstructions in the vehicle as possible. Lower frequency noises interfere more than higher frequency
noises. In case the ambient noise is too much, the Auto Setup program will quit with sad music and error code
#6.

8

Q: Can I put more than one KEY amplifi er in my car?
A: Yes, however the Auto Setup program is designed to optimize the front-sound stage only. Only one KEY

amplifi er can use the Auto Setup feature.

Q: Can I use the KEY amplifi er in addition to a subwoofer:
A: Yes, but care must be taken. Make sure you disconnect your subwoofer prior to the Auto Setup process. The
subwoofer must stay quiet during the Auto Setup so the KEY amp can hear what the car speakers sound like
without interference.

Upon successful completion of the Auto Setup, you can reconnect your subwoofer and use the crossover
switches on the KEY amplifi er to apply an adequate hi-pass to your speakers in order to match them with your
subwoofer. If you've forgotten to disconnect your subwoofer and it plays pink noise during Auto Setup, the Auto
Setup program will quit with sad music and error code #6.

Q: How does the Crossover work on the KEY amp?
A: In case no Auto Setup has been done, or the Auto Setup process was for Full-Range speakers (most cases),
the 24dB/octave Linkwitz-Riley Hi-pass crossover will be applied to all speakers. This crossover is user­selectable via DIP switches with the following options: OFF, 60 Hz, 80 Hz or 120 Hz.

In case of a Bi-Amp system with woofers and tweeters, the door speaker’s hi-pass is user selectable and the
lo-pass is 3.2 kHz 24 dB/octave. The tweeter’s hi-pass is also 3.2 kHz 24db/octave.

In case of a Bi-Amp system with door and dash woofers, the door woofer’s hi-pass is user selectable and the
low-pass is 640 Hz 24 dB/octave. The dash woofer’s hi-pass is 320 Hz 24db/octave. The overlap of 640 Hz
low-pass with 320 Hz hi-pass is done on purpose to enrich the mid-range. The Auto EQ takes care of trimming
excesses that can occur within this range.

Q: My Auto Setup program did not complete successfully, I am getting a sad song and beeps at the end. What
is it?
A: The beeps at the end are the error codes of the Auto Setup program. Upon failure, please count the number
of beeps after the sad song and troubleshoot with the information below.

Q: The Auto Setup process completed successfully, but I'm not happy with the sound. What other steps can I
take?

A: Ensure all speakers connected to the KEY amplifi er are wired in phase with each other. Be sure to check both
the amplifi er side and the speaker side of the wiring.

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 are Power (PWR)
& Protection (PRT) LEDs on the side panel of your KICKER KEY series amplifi er. Depending on the state of the
amplifi er and the vehicle’s charging system, the LEDs will glow either green or red. When the green LED is lit, this
indicates the amplifi er is turned on and no trouble exists.

Green 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.

Green 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.

Red (PRT) LED fl ickering with loud music? The red (PRT) 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.

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 6–16 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.

LIMITER LED on? Input signal overdrive or gain set too high: Reduce the gain or the strength of the input
signal. Thermal protection engaged due to heat sink temperature. Keep amplifi er in climate controlled cabin,
away from direct sunlight, or in a better ventilated area. Low input voltage (+12V line): Check your power
supply wires and battery voltage. Compression switch is on: If not desired, turn the compression switch off.

No or low output? Check the balance and fader controls on source unit. Check the RCA (or speaker
input) and speaker output connections. If using a Low-Level signal, make sure Radio Detect is OFF. Check
the volume level on your source unit, to include the volume level of any connected phones or MP3 players.

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.

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.

11

Cableado: Desconecte la batería del vehículo para evitar un cortocircuito eléctrico. Luego conecte el

cable de tierra al amplifi cador. Recorte el cable de tierra para que mida 24” (60 cm) o menos, y conéctelo
a un área de metal sólida libre de pintura y corrosión del chasis del vehículo. Se recomienda agregar otro
cable de tierra de esta longitud (o más largo) entre el polo negativo de la batería y el chasis del vehículo.
Mantenga alejado el cable de señal de audio de los arneses de cables de fábrica y otros cables de
alimentación. Si necesita cruzar estos cables, hágalo en un ángulo de 90 grados.

Corte el cable rojo de alimentación en bucle que se encuentra en el arnés de KEY y realice la instalación
utilizando un fusible de 20 A. El fusible debe estar como máximo a 18” (45 cm) de distancia de la batería
y en línea con el cable de alimentación del arnés, que se encuentra conectado a su amplifi cador. Si
alguna vez necesita retirar el amplifi cador del vehículo después de haberlo instalado, el último cable
que debe desconectar del amplifi cador es el cable de alimentación, lo contrario a lo que hizo cuando lo
instaló. El amplifi cador KEY puede utilizar el cableado directamente de su unidad de control, pero para
lograr los mejores resultados, se recomienda utilizar el cableado de tierra y alimentación de la batería y el
chasis del vehículo. KICKER recomienda un cable calibre 14.
