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
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. One thing to remember:
watts at 1 ohm. The point is, 800 watts is no greater than 800 watts no matter what impedance it is created at. 800
watts @ 2Ohms is NO greater than 800 watts at 4 Ohms!
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.
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.
If the voltage regularly fluctuates to this degree, a qualified installer needs to check it out!

800 watts at 4 ohms is equal to 800 watts at 2 ohms and is equal to 800
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
KickBass These KX amplifiers come with a variable 12 dB bass 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
Built-In Fixed Crossover These amplifiers have a built in 12 dB High pass or Low pass crossover. 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.

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.
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!

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.
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 of the amp will need
to be accessible for adjustment later. Keep this in
mind as you choose your amplifier’s mounting location.

connections. Drill 4 holes using a 7/64” drill bit and use the supplied #8 screws to mount the amplifier.
Now that you are ready to mount your amplifier, use the supplied 3mm allen wrench to remove the amplifier
With the shroud removed, you now have access to the four mounting holes in the mounting feet and all wiring
