Installation
Mounting
When selecting a location to mount your Kicker amplifier be
sure it is structurally sound and that there are no items behind
the area that could be damaged by the screws. Check for brake
lines, fuel lines, gas tanks, or wiring harnesses etc.
All amplifiers generate heat under normal operation. Be sure to
choose a location 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 EndKap. This
will give you access to the mounting holes in the amplifier and all
wiring connections.
With the EndKap removed, drill 4 holes using a 7/64” drill bit
and use the supplied #8 screws to mount the amplifier.

Installation
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 disconnect the battery to prevent
accidents.
Model Fuse Size Wire Size
KX-350.4 40A 8 GA
KX-650.4 80A 4 GA
KX-850.4 120A 2 GA
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 amplifier’s 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.
Wiring
Signal can be input into the amplifier using either the low level
RCA input connections 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.
All four channels will work with only one set of RCA cables, but
there will be no fade capability.

RCA Dummy Plugs
When using both sets of High Level inputs, RCA dummy plugs
must be inserted into the AMP 2 inputs in order for the fader to
work properly. If the amplifier is being used in any other
configuration do not use the RCA dummy plugs! If you do not
have dummy plugs available, simply using raw RCA ends or
cutting the ends off of existing cables will be sufficient. See the
Amplifier Technical manual for more information. DO NOT USE
SHORTING PLUGS!

Navigation
On your Kicker amplifier there are six rotary controls on top
and two switches on the end panel. These controls ensure the
reliability and performance of the amplifier, so they need to be
set correctly.
CROSSOVER SWITCHES
NEVER CHANGE THE CROSSOVER SWITCH SETTING WITH
THE SYSTEM ON!
The switches located on the end panel next to the RCA jacks
are 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 position should
be selected when connected to any speakers which you do not
want to receive sub-bass information.
BEFORE TURNING ON THE SYSTEM FOR THE FIRST TIME,
MAKE SURE THAT THE SIX ROTARY CONTROLS ON TOP
OF THE AMPLIFIER ARE TURNED FULLY
COUNTER-CLOCKWISE!
GAIN CONTROLS
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.
Adjust AMP 1 first, then proceed to AMP 2.
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.

Remote Bass Level
When using AMP 2 as a subwoofer amplifier 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.
