Features
Radically Advanced Chassis with removable shroud and improved heatsink technology. The heatsinks provide
the amplifier with longer runtime, improved reliability and performance. The height has been decreased for more
versatile installations. For those Livin’ Loud systems we offer custom paintable amplifier shrouds.
Low Impedance Operation The KX series amplifiers are stable down to 2 Ohm stereo and 4 Ohm mono. This
will allow the installer flexibility when designing the system. It will be easier to set up the right speaker impedance
for the amplifiers. (KX400.1, KX600.1 stable to 2 ohm mono and the KX1200.1 is stable to 1 ohm mono.) One thing
to remember: 800 watts at 4 ohms is equal to 800 watts at 2 ohms and is equal to 800 watts at 1 ohm.
SORT Protection Circuitry (Short circuit, Over-voltage, Reverse polarity, Thermal)
1. Short circuit- Protects the amplifier in case the speaker wire accidentally touches itself or the chassis of the car
or truck. This circuitry shuts down the amplifier before anything can cause damage requiring the need to be sent
in for repair.
2. Over-voltage- When the amplifier sees voltages above 16 volts or below 10.5 volts it will shut down to protect
the circuitry. If the voltage regularly fluctuates to this degree, a qualified installer needs to check it out!
3. Reverse polarity- When the power and ground are hooked up in reverse, the amplifier will blow the fuse or
fuses on the side of the amplifier. Just check the wires and replace the fuses and you’re up and running without
damaging the amplifier.
4. Thermal- At 185ºF the amplifier will shut down in order for it to cool. At 175ºF the amplifier will resume normal
operation. When the amplifier shuts down due to thermal protection it is wise to let it cool down. If it does not
have enough time to cool down, it will go into thermal protection immediately when you turn it back up to the
volume level at which it shut off. If this consistently becomes a problem, check the impedance of the woofer and
make sure the amplifier is properly ventilated
MOSFET Power Supply Kicker amplifiers use MOSFET(Metal Oxide Semiconductor Field Effect Transistor) devices
in our power supplies in order to gain more efficiency. MOSFET devices create a lot less heat than standard Bipolar
transistor devices and switch at 30K which is well out of the audible region. With these factors taken into account,
it is easy to see why our amplifiers are Livin’ Loud.
KickBass All of the KX amplifiers come with 18 dB of boost at 40Hz so you can tweak the low end of your system.
If your system is lacking a little in the low end or your system has a dip around 40Hz, you can adjust the control to
give you more KICK without adding an equalizer.
Built-In Variable Crossover The KX series have a built in 12 dB High pass or Low pass crossover variable from
50-200 Hz. If you are using the amp to run speakers that need crossover protection, flip the switch to HI PASS or if
you are using the amplifier to run subwoofers, flip the switch to LO PASS. Either way your amplifier will be able to
handle all of your needs. The crossover is defeatable for full range operation when there is no need for a crossover.
High & Low level inputs Whether you have a stock radio or an aftermarket stereo you will be able to hook up
the KX Series of amplifiers without the need for any adapters. High to low level adapters can rob your system of
important performance. We have eliminated the need for such adapters by building a series of amplifiers capable
of accepting a high or low level signal.

Features
PAST (Pre Amp Signal Transfer) Many systems contain more than one amplifier. We have included output RCA’s
that are capable of driving up to 10 amplifiers in a chain. We have eliminated the need for y-adapters that could
potentially induce noise into the system.(Only on the KX.1 And KX.2 amplifiers.)
Custom tooled gold plated connectors Assure maximum power transfer and damping.
SAMS (Stereo And Mono Simultaneously) Amplifier will operate into a bridged mono load and a stereo load at the
same time. This type of system is great if the consumer is just starting out, or on a tight budget.
Remote Bass Level Control (KX120.2, KX150.2, KX200.2, and KX300.4 not included.) When using a KX amplifier
equipped with an input jack, and the crossover set to LO PASS you are able to control the gain level of the amplifier
from the front of the vehicle. The KQ5 will control the KX amplifiers, just remember to plug the cable into the
amplifier. Just like the previous control, the Remote Bass level Control acts as an attenuator. Wherever the gain on
the amplifier is set, that is the highest level the control will reach.
Class D Mono Amplifier (KX mono amplifiers only.) Deliver Massive power, because of the efficiency that the
design offers. It delivers a ton of power into a single channel without straining the vehicles charging system. At
norma
al operating levels this amplifier design will be more efficient than the AB-Class design, although at full power,
it will draw just as much current as the AB amplifiers. Keep in mind the amount of time spent at full power is dramatically less than the time at lower power levels making this a very popular amplifier design.
Subsonic Filter 12 dB at 25Hz (KX mono amplifiers only.) When using a vented enclosure, the built in subsonic
filter, which is defeatable, will protect the woofer from damaging low frequencies and allow the amplifier to run
more efficiently in a smaller bandwidth..
Strapping Jacks(KX mono amplifiers only.) Using a mono 2 conductor cable terminated with a 3mm / 1/8” Tip
Sleeve connector, you can link two amplifiers together. The amplifier’s output is combined and produces mind
blowing Double Power to the woofers. Make sure you study the diagram explaining the process, otherwise very
bad things happen.
Forced Induction Cooling All models except the KX120.2, KX150.2, KX200.2, KX300.2 and the KX400.1. Helps to
exhaust the hot air that has built up inside of the amplifier during operation. The fan is activated when the amplifier get hot. As the temperature rises, the fan spins faster, circulating more air to cool the amplifier.
Three Year Warranty When you’re ‘Livin’ Loud’ you want the tunes to roll non-stop and we couldn’t agree
more. When you purchase your KX Amplifier from an authorized KICKER dealer we back it up with a full year warranty...parts and labor. If you have an authorized KICKER dealer install it for you at the time of purchase we push
that warranty out to a full THREE years! We build our products to give you years of trouble free performance and
know that if it is installed right the first time you will get just that...so we back it up!

Mounting Instructions
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 wiring, brake
lines, fuel lines, gas tanks, etc.
Remove

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 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
mounting holes in the amplifier and all wiring connections.
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.

KX.1 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. Connecting to the
amp with either input will provide a low level signal at the output (PAST) jacks. Do not use both methods of connections. Use either high level or low
level to connect the amplifier.

Wiring Instructions
Wiring cont.
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.
Source
Factory Wiring
Amplifier
When working with power connections it is always recommended that you disconnect 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.(See Diagram Below) 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. See diagram below.

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 on next page for wire size and fusing recommendations.

Forced Induction Cooling Vents
All models except the KX120.2, KX150.2, KX200.2, KX300.2, and the KX400.1 come with a fan to exhaust any heat
that has built up inside of the amplifier during operation. The thermally controlled fan uses a forced induction system to cool the operating temperature down to tolerable limits. When the amplifier gets hot, cool air is forced in
and the hot air is forced out. The hot air is exhausted through the vents on the top of the amplifier.

Screen Mounting
For custom installations we offer unpainted amplifier shrouds. They will need to be painted or customized to fit
your needs before mounting the screens. To mount the screen to the shroud, you will need to use an adhesive. A
common 5 minute epoxy will be sufficient. Run a bead of Epoxy on the inside face of the shroud and a bead on
the side wall of the shroud. Wait until completely dry before mounting the shroud on the amplifier. See diagram
below.

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
Front View
the appropriate jack on the amplifier chassis.
Note: The maximum level the Remote Bass
Level Control will achieve is dependent on
where the gain on the amplifier chassis is
set. Meaning, if the amplifier gain is set at
half, the controller is limited to that setting for volume. Below are two examples of using one controller to operate
more than one amplifier. Comes with a 25 ft. cord, enough for any installation.
Remember the Remote Bass Level control only works when the amplifier is in the LO pass mode and only controls
AMP 2 on the 4 channel models.
Here are some examples using the adapters to connect more than one amplifier to one Remote Bass
Level control. Either way will work, you just have to
decide which one fits your needs.

Crossover Control
Where you set the crossover is very subjective and can be fine tuned to match your listening preference or
speaker requirement. If the amplifier is driving small speakers (crossover set to HI PASS or ON) the tendency is to
set the frequency higher to eliminate the low frequencies from damaging the speaker. If the amplifier is driving
large subwoofers (crossover set to LO PASS) the tendency is to set the crossover frequency low. These are only
guidelines because setting the right frequency depends on the listeners preferences. What sounds good to one
may not sound good to another. The following guidelines should give you a good understanding for working with
our amplifiers.
HI PASS
When using the amplifier to drive high and midrange speakers you will need to set the switch to HI PASS or ON
depending on the amplifier model.
When using the amplifier to drive 4” speakers or smaller, a crossover point of 150 Hz or higher is recommended.
When using the amplifier to drive 5” - 6” speakers, a crossover point of 80 Hz or higher is recommended. Once
set, listen to material that you are familiar with before making any changes.
LO PASS
When using the amplifier to drive woofers the switch will need to be set to LO PASS
Although it is very subjective, when using 8” woofers or smaller a crossover point of 150 or below is recommended. When using 10” woofers or larger a crossover point below 100 is usually preferred. If you are using good midbass drivers (like the NEW RMB6 or RMB8) a lower crossover frequency will allow 12” or larger woofers to sound
cleaner.

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.
Depending on the limits of the system or the limits of the woofers the BassBoost Control will give your system
that extra kick. It will provide up to 18 dB of boost @ 40 Hz, which will more than make your system POUND!

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 if applicable. AMP 2 should be adjusted with the same process. If applicable,
the SUB amp will be adjusted next. If the Bass Boost is adjusted, the SUB amplifier gain must be re-adjusted to
insure the amplifier is not clipping.

One of the brand new features of the KX mono amplifiers is the ability to “strap” two amplifiers together. Using the cable supplied [ a longer one can be
purchased at Radio Shack (model # 42-2420) ] the two amplifiers can be linked together. This will effectively double the amount of power going to the
woofer(s). How can you do this? It is simple. First, you must have two amplifiers. Duh! Let’s call the first amplifier the Primary Amp and the other amplifier
the Secondary Amp. The mono cable should be plugged into the strapping jack labeled OUT on the Primary Amp, and the opposite end plugged into the
strapping jack on the Secondary Amp labeled IN. That’s it for the special cable. The next step is the speaker wire. The positive lead on the speaker should
be hooked to the positive terminal on the primary amplifier, while the negative speaker terminal should be connected to the positive speaker terminal on
the secondary amplifier. The negative terminal of each amplifier should be connected directly by a wire and must be a minimum of 16 gauge. Each amplifier should see no less than 2 ohms (KX400.1, KX600.1) or 1 ohm (KX1200.1). Strap only two of the same models together! Do not use more than one
strapping jack on the amplifier at a time! When strapped, the Secondary amplifier controls are bypassed.

The subsonic filter is useful when the user does not want harmful
low frequencies ( under 25 Hz) playing though the woofers. With the
switch in the ON position the subsonic filter is engaged. With the
switch in the OFF position the subsonic filter is not engaged and the

WARNING:
KICKER drivers are capable of producing sound levels that can permanently
damage your hearing! Turning up a system to a level that has audible distortion 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.
Pleaase use common sense when controlling volume!!
