KX Amplifiers
Installation
Navigation
On your Kicker amplifier there are five (seven on the KX700.5)
rotary controls on top and one (two on the KX700.5) switch(es)
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” 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 for the Class A/B
audio channels. In the OFF position the amplifier passes a full-
range signal to the speakers. 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 FIVE (SEVEN ON THE KX700.5)
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.
AMP 1 should be set first, then AMP 2 (KX700.5 only), and finally
the SUB input gain control.
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 SUB input gain control to avoid clipping the amplifier.
