KX Amplifiers
Navigation
On your Kicker amplifier there are six rotary controls on top
and two switches on the end panel. These controls ensure the
reliability and performance of the amplifier, so they need to be
set correctly.
CROSSOVER SWITCHES
NEVER CHANGE THE CROSSOVER SWITCH SETTING WITH
THE SYSTEM ON!
The switches located on the end panel next to the RCA jacks
are for setting the internal crossover. In the OFF position 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 any speakers which you do not
want to receive sub-bass information.
BEFORE TURNING ON THE SYSTEM FOR THE FIRST TIME,
MAKE SURE THAT THE SIX ROTARY CONTROLS ON TOP
OF THE AMPLIFIER ARE TURNED FULLY
COUNTER-CLOCKWISE!
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.
CROSSOVER CONTROL
Where you set the crossover is very subjective and can be fine
tuned to match your listening preference or speaker
requirements.
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.
