Operation
Your Kicker ZX.2 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. CrossoverSwitch The crossover switch on the end-panel is 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 speakers, which you do not want
to receive any sub-bass information.
Never change the crossover
"OFF/HI/LO" switch 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.
TroubleShooting
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.

recommended impedance and multiple speaker wiring suggestions). Also check for adequate airflow
around the amplifier. 2) Amplifier shuts down only while vehicle is running.
circuitry is engaged. Voltage to the amplifier is not within the 9-16 volt operating range. Have the
vehicle's charging and electrical system inspected. 3) Amplifier will only play at low volume levels.
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.
No output from one channel? 1) Check the balance control on source unit 2) Check the RCA (or
speaker input) and speaker output connections for the channel 3) Swap the RCA (or speaker input)
cable from left to right. If the problem changes sides then you have a bad RCA (or speaker input) cable

or source unit problem. 4) Swap the speaker output wire from left to right. If the problem changes
sides then you have a bad speaker cable, passive crossover network and/or speaker.
Alternator noise-whining sound with engine's RPM? 1) Check for damaged RCA (or speaker
input) cable 2) Check the routing of RCA (or speaker input) cable 3) Check the source unit for proper
grounding 4) Check the gain settings and turn them down if they are set too high.

speaker wiring, passive crossover networks and speaker terminals for proper positive and negative
connections. Reverse a speaker connection from positive to negative on the stereo/subwoofer
channel(s); if the bass improves, the speaker was out of phase.

Please Note: Modern high performance speakers have a lower DC Resistance than what used to be
available. The Kicker Coaxial and Component speakers are rated at four ohms (some DC Resistances
may be as low as 3 ohms) and work with any amplifier designed to operate at a four ohm load. If you
want to use two Kicker Coaxial or Component speakers on a single channel of your amplifier wire the
speakers in series. This will improve the sound quality, lower the total harmonic distortion and lessen the

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.
