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 , the shrouds may be painted to match your car!
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:
800 watts at 4 ohms is equal to 800 watts at 2 ohms and is equal to 800
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

1.
S
hort 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..
O
ver-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.
R
everse 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.
T
hermal- 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
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
KICK without adding an equalizer.
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.
