Operation
Your Kicker ZX.1 series amplifier has three rotary controls on top and one switch on the end-panel.
Before turning on the system for the first time, turn the three rotary controls on the top of the amplifier
to the full counter-clockwise position.
1. SubsonicFilterSwitch The subsonic filter switch located on the end-panel utilizes an internal
12dB per octave at 25 Hz high-pass
crossover in the ON position. The
setting for this control is subjective;
the ON position is a good place to
start. Never change the subsonic filter
switch "ON/OFF" setting with the
audio system on! See Figure 1.
2. InputGainControl The input gain
control is not a volume control. It
matches the output of the source unit
to the input level of the amplifier. Turn
the source unit up to about 3/4 volume (if the source unit goes to 30, turn it to 25). Next, slowly turn
(clockwise) the gain on the amplifier up until you can hear audible distortion, then turn it down a little.
3. BassBoostControl The bass boost control is designed to give you increased output 0 - 18dB
at 40 Hz. The setting for this control is subjective. If you turn it up, you must go back and adjust the
input gain control to avoid clipping the amplifier.
4. CrossoverControl The setting for this control is subjective; 80Hz is a good place to start.
5. RemoteBass(Level Control) With the remote bass level control you have the ability to control the
level of the subwoofer(s) remotely by controlling the output level of one or more ZX series amplifiers. To
mount the remote bass level control, simply screw the metal bracket to the chosen location. Then slide
the housing onto the bracket until it
snaps into place. Run the cable from
the controller to the "Remote Bass"
jack on the amplifier chassis.
TroubleShooting
Slide the housing until it snaps into the metal bracket
If your amplifier does not appear to
be working, check the obvious things
first such as blown fuses, poor or
incorrect wiring connections,
incorrect setting of crossover switch
and gain controls, etc. There are two
LEDs on the top of your Kicker ZX
series amplifier, one green and one
red. When the green LED is lit this indicates the amplifier is turned on and no trouble exists. If the green
LED turns off and the red LED is lit, this indicates that the protection circuitry (SORT) is engaged.
Green LED off, no output? With a Volt Ohm Meter (VOM) check the following: 1) +12 volt power
terminal (should read +12V to +16V) 2) Remote turn-on terminal (should read +12V to +16V)
3) Check for reversed power and ground connections 4) Ground terminal, for proper conductivity.
Green LED on, no output? Check the following: 1) RCA connections 2) Test speaker outputs
with a "known" good speaker. 3) Substitute source unit with a "known" good source unit. 4) Check
for a signal in the RCA cable feeding the amplifier with the "AC" test position selected on the VOM
meter.
Red LED on, no output? 1) Amplifier is very hot.

Short circuit protection is engaged. Check for speaker wires shorted to each other or to the vehicle
chassis. Check for damaged speakers, or speaker(s) operating below the minimum recommended
impedance.

CAUTION: When jump starting the vehicle, be sure that connections made with jumper cables are
correct. Improper connections can result in blown amplifier fuses as well as the failure of other critical
systems in the vehicle.
