KX Amplifiers
Operation
Navigation
On your Kicker amplifier there are three rotary controls on top
and one switch on the end panel. These controls ensure the
reliability and performance of the amplifier, so they need to be
set correctly.
CROSSOVER SWITCH
NEVER CHANGE THE CROSSOVER “OFF/HI/LOW” SWITCH
SETTING WITH THE AUDIO SYSTEM ON!
The crossover switch located on the end panel next to the
RCA jacks is for setting the internal crossover. In the OFF posi-
tion 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
speakers, which you do not want to receive any sub-bass
information.

BEFORE TURNING ON THE SYSTEM FOR THE FIRST TIME,
MAKE SURE THAT THE THREE ROTARY CONTROLS ON
TOP OF THE AMPLIFIER ARE TURNED FULLY
COUNTER-CLOCKWISE!
GAIN CONTROL
Remember, the input 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 (if the head unit goes to 30, turn it to
23). Next, turn (clockwise) the gain on the amplifier up slowly
until you can hear audible distortion, then turn it down just a little.
CROSSOVER CONTROL
Where you set the crossover is very subjective and can be fine
tuned to match your listening preference or speaker
requirements.
KickBass (Bass Boost Control)
The KickBass bass boost control is designed to give you
increased output 0 - 18dB at 40Hz. 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.
