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. Thermal protection is engaged. Test for proper impedance at the speaker terminals with a VOM meter (see the diagrams in this manual for minimum

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.

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.
The setting for this control is subjective; 80Hz is a good place to start.
2. InputGainControl The input gain control is not a volume control. It
matches the output of the source unit Crossover ControlInput Gain ControlBass Boost Control

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.
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.
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.
OPERATION
recommended impedance and multiple speaker wiring suggestions). Also check for adequate airflow around the amplifier. 2) Amplifier shuts down only while vehicle is running. Voltage protection 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 or low output? 1) Check the balance and fader control on source unit 2) Check the RCA (or speaker input) and speaker output connections

Reduced bass response? Check system phasing by reversing a speaker connection from positive to negative on the stereo/subwoofer channel(s); if the bass improves, the speaker was out of phase.
