Mounting Instructions

When selecting a location to mount your Kicker amplifier be sure it is struc-

turally sound and that there are no items behind the area that could be dam-

aged by the screws. Check for wiring, brake lines, fuel lines, gas tanks, etc.

All amplifiers generate heat under normal operation. Be sure to choose a loca-

tion that allows adequate ventilation for the amplifier. Also consider that the air

temperature inside an automobile’s trunk can reach upwards of 140 degrees

fahrenheit. An amplifier mounted here may require additional cooling needs

such as fans or venting to allow cool operation. If possible, mounting the amp in

the passenger compartment will allow cooler operation.

Remember that the controls on top of the amp will need to be accessible for

adjustment later. Keep this in mind as you choose your amplifier’s mounting

location.

Now that you are ready to mount your amplifier, use the supplied 3mm allen

wrench to remove the amplifier shroud. This will give you access to the mount-

ing holes in the amplifier and all wiring connections.

Remove Remove

With the shroud removed, you now have access to the four mounting holes in

the mounting feet and all wiring connections. Drill 4 holes using a 7/64” drill bit

and use the supplied #8 screws to mount the amplifier.

Wiring Instructions

Signal can be input into the amplifier using either the low level RCA input con-

nections or the high level speaker level connections. Using the low level RCA

connections is the preferred method. Use the high level inputs only if your head

unit does not have low level RCA type outputs. Connecting to the amp with

either input will provide a low level signal at the output (PAST)jacks.

The use of twisted pair interconnects is recommended for all installations to

minimize noise. When routing these cables through the automobile, try to keep

them away from factory wiring harnesses and other power wiring. If you need to

cross any of this wiring do so at a 90 degree angle to reduce the possibility for

noise problems.

When working with power connections it is always recommended that you dis-

connect the battery to prevent accidents.

The ground should be connected to the amplifier first before making any of

the other connections. This wire should be as short as possible (24 inches or less)

and connected to a paint/corrosion free solid metal area of the car’s chassis. Use

the same gauge wire as recommended for the amplifiers power connection to

the battery. Adding an additional ground wire between the car battery’s negative

post and the car chassis of this same gauge (or larger) is also recommended.

If you ever need to remove the amp 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.

A fuse must be installed within 18 inches of the battery to protect the power

wire feeding your amplifier. This fuse should be of at least the same value used

in the amplifier but no higher than the capacity of the wire. See the chart below

for wire size and fusing recommendations.

REMOTE BASS LEVEL CONTROL

When the crossover on your KX series amplifier is set to LO PASS, you have

the ability to control the output level of the amplifier from the driver’s seat

using the supplied Remote Bass Level Controller.

To mount the controller simply screw the metal bracket to the chosen location

and then slide the housing onto the bracket until it snaps into place.

Run the cable from the controller to the appropriate jack on the amplifier

chassis.

STEREO AND MONO SIMULTANEOUSLY (SAMS)

KX series amplifiers are capable of operating into a minimum impedance of 4

crossovers.

USING THE SIGNAL OUTPUT JACKS (STOP)

The Output (Pre Amp Signal Transfer) RCA jacks allow you to send the

incoming signal from one Kicker KX series amplifier to another amplifier or

processor without the need for Y cables. The signal from the PAST jacks is iden-

tical to the signal fed to the amplifier via its RCA input jacks or the High Level

inputs and is not affected by the amplifier’s built in crossover.

Most head units with high voltage outputs should be capable of driving up to

ten amplifiers in a chain.

ADJUSTING AMPLIFIER CONTROLS

On your Kicker amplifier there are three rotary controls on top and one switch

on the end panel. These controls ensure the reliability and performance of the

amplifier, so they need to be set correctly.

CROSSOVER SWITCH

NEVER CCHANGE TTHE CCROSSOVER SSWITCH SSETTING WWITH TTHE SSYSTEM OON!

The switch located on the end panel next to the RCA jacks is for setting the

internal crossover. In the OFF position the amplifier passes a full range signal to

the speakers. Use the LO position when connected to a subwoofer. The HI posi-

tion should be selected when connected to any speakers which you do not want

to receive sub-bass information.

BEFORE TTURNING OONTTHE SSYSTEM FFOR TTHE FFIRST TTIME, MMAKE SSURE TTHAT

THE TTHREE RROTARY CCONTROLS OONTTOP OOFTTHE AAMPLIFIER AARE

TURNED FFULLY CCOUNTER-CCLOCKWISE!

GAIN CONTROL

Remember, the gain control is not a volume control, it matches the output of

the head unit to the input level of the amplifier and must be adjusted properly

for best performance. All the way up or down is not necessarily the best.

Turn the head unit up to about 3/4 volume. (eg. If the head unit goes to 30,

turn it to 25.) Next, turn (clockwise) the gain on the amplifier up slowly until you

can hear audible distortion, then turn it down just a little.

Crossover Control

Where you set the crossover is very subjective and can be fine tuned to match

your listening preference or speaker requirements.

Bass Boost

The BASS BOOST control is designed to give you increased output at 40 Hz. The

setting for this control is subjective, however, if you turn it up, you must go

back and adjust the gain control to avoid clipping the amplifier.

TROUBLE SHOOTING

If your amplifier does not appear to be working, check obvious things first

such as blown fuses, poor or incorrect wiring connections, incorrect setting of

crossover switch and gain controls, etc.

There are two LEDs on the end panel of your Kicker KX series amplifier, one

green and one red. When the green LED is lit this indicates the amplifier is

turned on and no trouble exists. If the green LED turns off and the red LED is lit

this indicates that the protection circuitry (SORT) is engaged.

The power indicator on top of the amplifier which illuminates the model

badge follows the same function as the green LED.

Green LLED ooff, nnoooutput:

Wiith aaVVolltOOhm MMeter ((VOM) ccheckk:

Ö+12 volt power terminal (should read +12V to +16V).

ÖRemote turn-on terminal (should read +12V to +16V).

ÖGround terminal.

Green LLED oon, nnoooutput:

ÖCheck RCA connections.

ÖTest speaker outputs with known good speaker.

ÖSubstitute known good source unit.

ÖCheck for signal on RCA cable with VOM meter in AC position.

Red LLED oon, nnoooutput:

1.) Amp is very hot.

ÖThermal protection is engaged. Check for proper impedance at

speaker terminals. Also check for adequate airflow around amplifier.

2.) Amp shuts down only while vehicle is running.

ÖVoltage protection is engaged. Voltage to the amplifier is not within

the 9-16 volt operating range. Have automobile charging/electrical

system inspected.

3.) Amp will only play at low volume levels.

ÖShort circuit protection is engaged. Check for speaker wires shorted

to each other or the vehicle chassis. Damaged speakers or operating

below minimum impedance will also cause this.

No ooutput ffrom oone cchannel:

ÖCheck balance control on head unit.

ÖCheck RCA & speaker connections for that channel.

ÖSwap RCA connections from left to right.

If problem changes sides then you have a bad RCA

cable or source unit problem.

ÖSwap speaker connections from left to right.

If problem changes sides then you have a bad speaker

cable or bad speaker.

Alternator nnoise ((whining ssound tthat vvaries wwith eengine RRPM):

ÖCheck for damaged RCA cable.

ÖCheck routing of RCA cable.

ÖCheck source unit for good ground.

ÖCheck gain setting, turn down if set too high.

Poor sstereo iimage oorrreduced bbass rresponse:

ÖCheck system phasing by turning the balance control from left to

right. If there is more bass output when turned to either side then

check your speaker wiring for proper positive and negative connections.

Reverse connections on one channel if necessary.
