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 where the screws will

be driven that could be damaged. Check for wire harnesses, 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 automobiles trunk can reach upwards of 140 degrees

fahrenheit. An amplifier mounted here may require additional cooling tactics

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

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.

Remote Bass Level Control

When using the Remote Bass Level Control you have the ability to control the

level of the subs from the driver’s seat. To mount the controller simply screw the

metal bracket to the chosen location, 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.

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 potential of

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 amplifier, 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.

Stereo Operation with Subwoofer

KX amplifiers are capable of operating into a minimum impedance of 2 ohms

per channel in stereo operation and 2 Ohm mono on the subwoofer channel.

All Channels Bridged

The KX700.5 is capable of bridged operation on AMP 1 and AMP 2. This, for

example, would allow you to bridge AMP 1 to run the Right side and AMP 2 to

run the Left side.

But remember AMP 1 and AMP 2 are only stable down to 4

ohm mono.

Adjusting Amplifier Controls

On your Kicker amplifier there are Five (Seven on the KX700.5) rotary controls

on top and one (two on the KX700.5) switch(es) on the end panel. These con-

trols ensure the reliability and performance of the amplifier, so they need to be

set correctly.

CROSSOVER SWITCH

NEVER CHHANGE THE CRROSSOVER SWITCHH SETTING WITH THE SYSTEM ON!

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. The HI position should be selected when connected to any speak-

ers which you do not want to receive sub-bass information.

BEFORE TURNING ON THE SYSTEM FOR THE FIRST TIME, MAKE SURE THAT

THE FIVE (SEVEN ON THE KX700.5) ROTARY COONTROLS ON TOP OF THE AMPLIFIER

ARE TURNED FULLY COOUNTER-CLLOCKKWISE!

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. AMP 1 should be set

first, then AMP 2 (KX700.5 only) and finally the SUB.

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.

Troubleshooting

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

such as blown fuses, poor or incorrect wiring connections, crossover and gain

controls set incorrectly, 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 LED off,, no output::

With a Volt Ohm Meter (VOM) check::

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

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

ÖGround terminal.

Green LED on,, no output::

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 LED on,, no output::

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 output from one chaannel::

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.

Alternaator noise (whining sound thaat vaaries with engine RPM):

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 stereo imaage or reduced baass response::

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.

CAAUTION: When jump staarting the vehicle,, be sure thaat connections maade with

jumper caables are correct.. Improper connections caan result in blown amplifier

fuses as well as faailure in other systems in the vehicle..

KICKER drivers are capable of producing sound levels that can permanently

damage your hearing! Turning up a system to a level that has audible distor-

tion is more damaging to your ears than listening to an undistorted system

at the same volume level. The threshold of pain is always an indicator that

the sound level is too loud and may permanently damage your hearing.

PPleaase use common sense when controlling volume!!
