Warhorse: Defined as “Horses specially trained for use in battle or individual combat”.
As early as the 19th Century BC the Warhorse was used in chariot warfare. By the first century BC
the Warhorse carried Parthian archers into battle. By the Middle Ages the Warhorse had developed
into a large horse with the strength and stamina to carry a Knight and his heavy armor into battle. The
Warhorse of this era wore its own armor and was a magnificent beast. The best were selected for speed
and trainability. It was an expensive feat to train and outfit these tools of war. It took a lot of time to
overcome the natural aversion to the smell of blood and its natural disinclination to trample people. They
were even trained to kick, strike and bite on command.
In light of all this, Kicker’s newest and largest amplifier is named Warhorse. Born to do battle and
trained to excel, the Warhorse is like nothing available in the car audio arena. Conventional wisdom and
technology weren’t good enough for Kicker when we designed this 10,000 watt beast. Traditional Class
A/B design was entirely too inefficient and even more advanced Class D architecture wasted too much
battery power.
Efficiency is the “Holy Grail” of car stereo amplification, especially in SPL competition lanes. Warhorse’s
ultra-high efficiency allows competitors (as well as power hungry consumers) to create the huge
amounts of power they demand without relying on huge banks of amplifiers and the correspondingly
huge charging systems required with conventional amplifiers. By approaching the challenge of delivering
massive power from a new direction, Kicker engineers have created a system that lets users concentrate
their investments where they count – in actual sound reproduction equipment, instead of batteries,
alternators, or other charging system components. Signal quality is also critical to the demanding
high-end user, so in addition to the amplifier’s prodigious output capability, a full complement of built-in
control (crossovers, subsonic filter, bass boost, limiter, and more) allow precise tuning of your bass. A
broad assortment of protection and diagnostic circuits are also provided, allowing further performance
optimization.
KICKER’S signal-modulated power supply technology represents the first significant advance in amplifier
efficiency since Class D designs overtook Class A/B. Even though Class D was a great improvement
over A/B, Around 30% of available power was still wasted. While earlier technologies use power supplies
combined with gain circuits to amplify the audio signal, the Warhorse amplifies the audio signal directly
1

WX10000.1TechnicalManual
from its signal-modulated power supply, eliminating many power-wasting components common to
conventional designs. The signal-modulated power supply amplifies each polarity of the audio signal
separately through two voice coil outputs, each driving one coil of a dual-voice coil subwoofer or DVC
subwoofer array. This fresh approach… essentially a power supply with gain… results in efficiencies
greater than 90%! SPL competitors will find this very attractive and advantageous as they seek to
wring those elusive last few decibels from their vehicle. Consumers anxious to experience cutting edge
technology will appreciate the amplifier’s ability to interface with a broad range of components and
vehicles.
The idea of a signal modulated power supply directly driving the subwoofers is an idea that we have
thought about for a few decades. Combining the conventional power supply with the amplifier section
results in higher efficiency than is possible with established designs. When building an amplifier this
powerful, efficient conversion of battery power to audio power is critical.
The basis for the Warhorse is anchored in conventional designs. There are two large DC-to-DC pulse
width modulated converters with ratios of 1:19. One converter is a positive power supply and the other
is a negative supply. Combined they are capable of 400V of peak to peak output. These power supplies
are designed to have no output until they are told to by the audio signal. Without a signal the converters
are running with the minimum pulse width.
These large converters have to be bulletproof. The MOSFETs used to do the switching are rated at
75 Volts and 170 Amps. Since there are 32 of these MOSFETs on each side of the power supply the
combined current capability is 10,880 Amps! With the output short-circuit protected at 90 Amps, the
maximum capability of the Warhorse is 12,690 Watts. That should qualify as overbuilt. The MOSFETs
chosen are the best devices to get the job done. Their typical 3.6 mili-ohms of “on” resistance is the best
available for this application, resulting in best-case efficiency.
The small-signal processing is done in the digital domain using a modern Texas Instruments 150 M Hz
CMOS 32 bit CPU. This processor has a 12 bit ADC and 16 channels.
The Warhorse has multiple “housekeeping” power supplies to operate the processors, LEDs, protection
circuits and preamp parts. They include a + 12 Volt, +/- 5 Volt and a +3.3 Volt supply.
Transformers are among the most important
parts in a high-powered mobile amplifier.
KICKER engineers were tasked with
building a no-compromise amplifier, so no-
compromise transformers were paramount.
Back in the 80’s our military began using
Planar transformer design for their desirable
properties. We use very special proprietary
Planar transformers designed and prototyped
in the Kicker R&D department. Production of
the transformers in quantity has been sourced
from Tunisia. There is only one source for
transformer cores this large. The cores are
rated at 5,000 watts each and four are in
each Warhorse amplifier.
2

WX10000.1TechnicalManual
There are five extremely good reasons why the Planar design is best for the Warhorse.
By design, a Planar style of transformer has the lowest leakage inductance. This is very important1.
from an engineering standpoint because of the extremely high current level needed to produce 10,000
Watts. The coupling between the primary and secondary is much better than with any other design.
They have an ultra low profile for the electrical rating. With the winding being flat and glued to2.
the ferrite core the transformers are very tough. The primary windings are screwed to the buss bars,
increasing stability and providing reliable high-current connections.
Since they have the best surface-to-volume3.
ratio, cooling is better than that of conventional
toroidal transformers.
With other types of transformers, it is difficult4.
to get consistent properties relating to the
wrapping of the windings. The physical layout
of the Planar transformer allows it to be built the
same way each time for very consistent results.
A high turn ratio is impractical with the other5.
transformer designs. In the Planar transformer we
can easily reach the 19:1 ratio needed to get the
voltage used in a 10,000 Watt amp.
The switching frequency is 24 KHz, yielding a much easier to filter 48 KHz ripple after the full wave
rectifiers. The output of this signal-modulated power supply is filtered by two over-built toroidal output
coils. Spike suppression is accomplished with filters utilizing eight 35 Watt snubber resistors. Worst case
for these filters is seen at full output.
The printed circuit board (PCB) for an amplifier this large has to be stronger than normal. The Kicker
Warhorse components are mounted on a thicker (.090”, 2.5 mm) than usual fiberglass PCB with much
heavier (4 ounce) copper traces.
In order to optimize the circuit board layout the battery power connectors needed to be near the top
center of the amplifier chassis. There are three 1/0 gauge sized proprietary gold plated brass connectors
for the negative ground connections and three more for the positive connections. These connectors are
bolted to symmetrical copper buss bars for power distribution within the chassis.
3

WX10000.1TechnicalManual
Since the output current to the subwoofers can reach 90 amperes, the connectors must be extremely
rugged. We chose AndersonTM connectors because they have been proven to hold up under demanding
high current applications (such as industrial fork lifts). They are also ideal due to the fully enclosed design
which helps eliminate the chance for electrocution. The output current is monitored by surface mount
resistors that are referenced to ground and calibrated for 90 amps RMS. When that level is reached the
DSP controller shuts the amplifier down in microseconds to prevent damage to any components.
The switching MOSFETs need to be bulletproof, so they utilize thermally conductive interface material.
This insulated metal substrate minimizes the thermal impedance and conducts heat away from the
MOSFETs more efficiently than conventional mounting methods.
In conclusion, the Kicker Warhorse WX10000.1 has the highest power output available in a single
channel mobile amplifier, the best conversion efficiency from battery power to audio power, the lowest
idle current and the best power to size/weight ratio.

The Kicker Warhorse amplifier was specifically designed for competition car audio. Sporting 10,000
RMS watts of pure Kicker power, the ultra-high-efficiency design of the WX amplifier revolutionizes
traditional methods of amplification. While most amplifiers use a power supply combined with an
amplification circuit to amplify the audio signal, the Warhorse skips a step by amplifying the audio
signal directly from its patent pending signal-modulated power supply. The signal-modulated power
supply amplifies each polarity of the audio signal separately through its two voice coil outputs to
optimally drive dual-voice coil subwoofers and provide a competitive edge in SPL contests. From gold
plated power connectors and low profile planar transformers to the latest Texas Instruments DSP
technology, no expense was spared to make the Warhorse the most powerful and efficient mono
amplifier in mobile audio.
Installation . . . as easy as 1, 2, 3
1. Mounting Choose a structurally sound location to mount your Kicker amplifier. The amplifier should
be mounted as close as possible to the battery network and be electrically isolated from the vehicle
ground. The distance from the battery network to the amplifier should not exceed 48” (122cm). It is
important to mount the amplifier before running any wires or supplying power to the amplifier. The
amplifier secures to the vehicle with an insertable mounting bracket used in combination with two
mounting holes located on the bottom plate of the control panel. You are solely responsible for securely
fastening the WX amplifier in your vehicle.
Before mounting the amplifier, the control panel shield must be removed. The control panel should
remain accessible for adjustment, leaving enough room to access the mounting holes and remove or
attach the control panel shield. 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 amplifier. After
choosing the best location, secure the mounting bracket to the vehicle. Use the bracket as a template
to drill nine (9) holes with a 3/16” (4.8mm) bit into the appropriate locations. Attach the bracket to the
mounting location with the nine (9) supplied #10 (5mm) screws inserted through the nine (9) included
screw insulators.
Next, slide the amplifier over the mounting bracket and into the mounting slot. Make sure the mounting
bracket is properly inserted into the mounting slot and locate the two mounting holes on the bottom
plate of the control panel. Use the mounting holes as a template and drill two (2) holes using a 3/16”
(4.8mm) bit into the appropriate locations. Secure the bottom plate of the control panel with the two (2)
#10 (5mm) screws.
Caution The Kicker WX amplifier outputs extremely high voltage signals
from the voice coil (speaker) outputs and can cause serious injury or death
from electrocution. It is imperative to read the manual carefully and follow all
of the recommended safety precautions before installing the WX amplifier.
The patent pending signal-modulated
design of the Warhorse amplifier is the
most powerful and efficient design
available in mobile audio, rated at 90%
efficiency at full power with a 2 ohm load.
The graph compares the Warhorse
amplifier’s efficiency ratings to those of
industry standard Class D amplifiers.

2. Wiring Before wiring the Warhorse amplifier, disconnect the vehicle’s batteries to avoid an electrical
short. Eight (8) identical, high-quality, 800-cold-cranking-ampere (cca), 12-volt batteries are
recommended to power the WX amplifier. All power and ground wires should be as short as possible
and utilize 1/0 gauge wire. Remove the wire guide and power hood from the amplifier as shown in
Figure 3. Connect three (3) ground wires from the amplifier’s negative power connector to the negative
terminals of three (3) batteries in the battery network.
From two (2) of the batteries in the battery network, connect 1/0 gauge ground wire from the negative
terminals of the batteries to a paint-free and corrosion-free solid-metal area of the vehicle's chassis.
Make the ground wires short, 18” (45cm) or less. To reduce noise, make sure the ground wires connect
to the same piece of metal and are within 18” (45cm) of each other.
With the control panel shield removed, connect a twisted pair of RCA (low-level) interconnect cable,
carrying the incoming audio signal, to the RCA inputs on the amplifier. Connect the speaker wires to the
supplied AndersonTM connectors. Use 8 gauge wire and strip 9/16” (14mm) from the end being
inserted into the metal contacts. See Figure 5. The wire should be secured by placing the metal contact
into a vise and melting solder inside the metal contact. Then, insert the stripped wire into the molten
solder within the contact. Do not use acid core solder.
The Warhorse amplifier requires at least two (2) 200-ampere-output-capacity alternators. For each
alternator, connect a 250 ampere fuse within 18” (45cm) of each alternator and a second 250 ampere
fuse within 18” (45cm) of the battery network. Without adequate charging capability, the WX amplifier
can draw enough current to shut down your vehicle’s computer system. This may adversely affect your
ability to control your vehicle. See Figure 4.
The three (3) positive 1/0 gauge power wires should be the last wires connected in the installation.
Install the supplied Kicker three (3) gang ANL fuse holder within 18” (45cm) of the battery network and
in-line with the three (3) power cables connected to the amplifier’s positive power connector. Improper
connections will damage the amplifier and/or cause serious injury or death. If you ever need to remove
the amplifier from the vehicle after it has been installed, the ground wires should be the last wires
disconnected from the amplifier, just the opposite as when you installed it. See Figure 4.

Operation
Within the control panel shield, the Kicker WX amplifier has five (5) rotary controls, input jacks for the
Remote Bass level control, and input/output jacks for the optional WX control module. The control
panel delivers a full range of options for processing the signal that powers your subwoofers. To remove
the control panel shield, simply remove the two (2) screws as shown in Figure 5.
1. InputGainControl The input gain control is not a volume control. It matches the output of the
source unit to the input level of the amplifier. Please use hearing protection before performing the
following procedure. Disconnect the Remote Bass level control and turn the source unit up to about
3/4 volume (if the source unit goes to 30, turn it to 25). Next, slowly turn (clockwise) the gain on the
amplifier up until you can hear audible distortion, then turn it down a little.
2. BassBoostControl The bass boost control is designed to give you increased output 0 - 18dB
at 40 Hz. The setting for this control is subjective. If you turn it up, you must go back and adjust the
input gain control to avoid clipping the amplifier.
3. HighPassSubsonicCrossover The variable high-pass crossover located on the control panel
utilizes a 24dB per octave 20 - 60Hz high-pass crossover. The setting for this control is subjective but
should be adjusted to appropriately accommodate your enclosure in order to prevent damage from high
excursion and increase the power handling of the subwoofer(s).
4. LowPassCrossover The variable low-pass crossover located on the control panel utilizes a
24dB per octave 50 - 200Hz low-pass filter. The setting for this control is subjective; 80 Hz is a good
place to start.
5. AdjustableLimiterControl The limiter adjusts the maximum RMS output of the Warhorse. If your
vehicle’s charging system is inadequate to provide full power to the WX series amplifier, adjust the limiter
control clockwise to reduce the amplifier’s power consumption and maintain an operational level that will
protect your subwoofer(s) from damage. If the <VOLT LED is on and the amplifier is frequently shutting
down due to under voltage, try turning the limiter control up (clockwise) until this is no longer a problem.
6. RemoteBass(Level Control) With the remote bass level control, you have the ability to control the
level of the subwoofer(s) remotely. To mount the remote bass level control, 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 “Remote Bass” jack on the amplifier chassis. See Figure 6.
7. WarhorseControlModule The optional Warhorse control module opens up a wide range of
operational possibilities within the Warhorse. The control module can simultaneously control up to 16
WX amplifiers and puts additional signal processing features in the palm of your hand. These include
bandpass crossover with adjustable slopes, limiter adjustment, phase inversion, single-band parametric
equalization, voltage range adjustment, battery voltage display, tone generator, and individual amplifier
muting. Contact your Kicker dealer for more information about the Warhorse control module and its
features. It is necessary to purchase the control module to access the full range of possibilities available
from your Kicker Warhorse amplifier.

4. >VOLT LED on/off The Over Voltage LED turns on when the voltage supplied to the amplifier
exceeds 16 volts and the muted safe mode has been activated. After the voltage supply drops below
15.5 volts, the amplifier will automatically turn back on.
5. X-BNDW LED on/off Because of the combined high pass and low pass filters built into the
rotary control section of the amplifier, it is possible to cause a reduction in output by adjusting the
bandwidth too narrow or overlapping the high and low pass crossover frequencies. The X-BNDW LED
turns on if this has occurred and is causing a reduction in output.
6. >TEMP LED on/off If the temperature of the amplifier’s heatsink exceeds 158F (70C), it will
activate the muted safe mode. When the temperature decreases to 149F (65C), the amplifier will
automatically turn back on. If this LED is on, turn the amplifier off and test resistance at the speaker
terminals with a digital multimeter (see Figure 6 in this manual for multiple speaker wiring suggestions).
Also, check for adequate airflow around the amplifier.
7. Short LED on/off The short LED will light up if the electrical current coming out of the amplifier’s
voice coil (speaker) outputs exceeds a peak of 130 ampere. The Warhorse Amplifier tests the outputs
every three (3) seconds to protect the amplifier from electrical shorts and will turn off automatically if any
short is detected. With the amplifier turned off and speakers disconnected, check for speaker wires
shorted to each other or to the vehicle’s chassis. Check for damaged speaker(s), or speaker(s)
operating below the minimum recommended impedance. Because of the dangerous voltage output of
the amplifier, it is important to turn the amplifier off before attempting to repair any short or problem with
the voice coil output wiring.
8. Service LED on/off If the service LED turns on, the amplifier most likely requires repair. In some
cases, the service LED will illuminate if the voice coil (speaker) outputs are not both loaded at the same
time. Turn the amplifier off and check the wiring for abrasions. Make sure that the amplifier is wired
correctly to the speakers as indicated in Figure 6. If no problems are found with the speaker wire or
connections and the service LED remains on, contact the Authorized Kicker dealer from whom you
purchased the amplifier.

OPERATION
TroubleShooting
If your amplifier does not appear to be working, check the obvious things first: such as blown fuses,
poor or incorrect wiring connections, incorrect setting of crossover switch and gain controls, etc. There
are eight LEDs on the control panel of your Kicker WX series amplifier. The LED display may help
identify the problem. The amplifier’s protection circuitry induces a muted safe mode if any excessive
conditions have occurred outside of the amplifier’s normal operational range. These conditions are
indicated by the LEDs on the amplifier’s control panel.
1. PWR LED on/off Smart power indicator turns
on when the amplifier is on and functioning properly.
2. NET LED on/off Indicates the optional remote
control module is connected to the Control Module
DIN input on the amplifier. See Figure 8.
3. <VOLT LED on/off The Under Voltage LED
turns on when the voltage supplied to the amplifier drops below 9 volts. The amplifier will remain in the
muted safe mode until the voltage supply increases to 9.5 volts. If the amplifier goes into mute mode
often, as a result of under voltage, you may need to do one or more of the following: a) turn up the
limiter control on the amplifier’s control panel, b) check the connections, c) replace batteries with
identical units or charge existing batteries, d) add additional identical batteries to the vehicle’s battery
network, e) add an additional alternator to your vehicle.
The Warhorse LED array
displays the status of the
amplifier’s protective
circuitry and can assist in
troubleshooting problems
that may occur while using
the amplifier. The green
LED’s will turn on or off
depending on the
conditions listed in this
section.
Figure 10
Without adequate charging capability, the WX amplifier can draw
enough current to shut down your vehicle’s computer system.
This may adversely affect your ability to control your vehicle.
The WX amplifier outputs dangerous voltage levels from the voice coil (speaker) outputs.
Never contact the voice coil outputs, connect speakers, or speaker wires if the amplifier is
turned on. Turning the amplifier on without loading both voice coil outputs or connecting
the speaker(s) will increase the risk of electrical shock and could damage the amplifier.

WarhorseDesignFeatures
1. Patent Pending Signal-Modulated Power Supply The WX amplifier’s patent pending signal
modulated power supply combined with its custom planar transformers achieves efficiency ratings yet
to be matched in mobile audio, operating at 90% efficiency at a 2 ohm load and 93% efficiency at a 4
ohm load at full power.
2. Planar Transformer Design The WX amplifier’s four (4) planar transformers are excellent for high
power applications and are custom designed to handle 5,000 watts each, leaving more than enough
power headroom to operate reliably and consistently at full RMS with 20,000 watts of total capability.
3. Texas Instruments DSP The Warhorse uses the latest Texas Instruments industrial grade DSP to
handle the amplifier’s pulse-width modulation, manage signal processing, and control the amplifier’s
protection circuitry.
4. Insulated Metal Substrate Cooling The Warhorse design uses insulated aluminum material for
optimum heat transfer between power devices and the heatsink. Lower operating temperatures improve
performance and durability while allowing for a smaller overall footprint.
5. Heavy Duty Industrial Bus Bars The Warhorse has been outfitted with solid copper industrial grade
bus bars. With 70 square millimeters of cross sectional area, the WX amplifier’s heavy duty bus bars are
specifically engineered to maximize the current carrying capability within the amplifier.
6. Super Thick, 4 Ounce Double Sided PCB When you are livin’ this loud, you have to have a strong
foundation. The circuit board used in the Warhorse is 50% thicker t
han
the industry standard and uses
the heaviest available 4 ounce thick copper traces and plated-through holes. This assures the circuit
board can transfer the current needed for an amplifier of this magnitude.
7. Oversized Gold Plated Power Connectors The Warhorse amplifier’s gold plated power connectors
were custom designed with multiple power terminals to maximize current carrying capability to the
amplifier’s signal-modulated power supply.
8. Industrial Grade AndersonTM Speaker Connectors The 50 ampere AndersonTM connectors
packaged with the Warhorse amplifier allow minimal contact resistance at high current. The housing of
the connectors was designed to prevent polarity mismatches when connecting speakers and also
protects fingers or probes from touching the metal contacts to provide additional safety from the high
voltage signals coming from the voice coil (speaker) outputs.
9. Dual Thermostatically-Controlled Push-Pull Cooling Fans Twin push-pull fans are mounted on the
side of the amplifier to improve airflow and provide additional cooling for the amplifier.
