+12V DC AUDIO

1. Automatic Turn-On Selection The ZX series offers three different automatic turn-on modes that can be

selected on the end panel; +12V, DC Offset, and Audio. Using either the DC Offset or Audio mode causes

the REM terminal to have +12V out for turning on additional ampliﬁ ers.

Remote Turn-On Set the switch to +12V to use the remote turn-on lead from your source unit. Run

18 Ga wire from the Remote Turn-On Lead on your source unit to the terminal labeled REM between the

ampliﬁ er's positive and negative power terminals. This is the preferred automatic turn-on method.

DC Offset Turn-On If Remote Turn-On is not an option, the next best setting is DC Offset. The DC

Offset mode detects a 6 volt surge from the HI Level speaker outputs when the source unit has been

turned on.

Signal Sense Turn-On The Audio setting is the ﬁ nal alternative for Automatic turn-on. This is a Signal

Sense turn-on method that detects the incoming audio signal from your source unit and automatically turns

on the amp. This turn-on method will not work properly if the input gain control is not set appropriately.

2. Input Level The RCA inputs on Kicker ZX ampliﬁ ers are capable of receiving either Hi or Low-level

signals from your source unit. If the only output available from your source unit is a Hi-Level signal, simply

press in the Input Level switch on the ampliﬁ er. Refer to the wiring section of this manual additional

instructions.

3. Crossover Switch Use the XOVER switch on the end panel of the ampliﬁ er to set the internal crossover

to OFF or HI. When the switch is set to OFF, a full bandwidth signal will be ampliﬁ ed. Set the switch to HI if

you want the ampliﬁ er's internal crossover to serve as a high-pass ﬁ lter. Never change the crossover "OFF/

HI" switch setting with the audio system on!

4. Input Gain Control The input gain control is not a volume control. It matches the output of the source

unit to the input level of the ampliﬁ er. 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 ampliﬁ er up until you can hear audible

distortion, then turn it down a little.

5. Bass Boost Control The variable bass boost control on the top of the ampliﬁ er 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 ampliﬁ er.

6. Crossover Control The variable crossover on the top of the ampliﬁ er allows you to adjust the crossover

frequency from 50-200Hz. The setting for this control is subjective; 80Hz is a good place to start.

7. Sub Input If there is no dedicated output on your source unit for subwoofer, use the SUB INPUT switch

to set your subwoofer input to either SUB INPUT or AMP INPUT 1.

8. RemoteBass(Level Control) When using the

remote bass level control you have the ability to

control the level of the Subwoofer Channel's output

remotely. 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 ampliﬁ er chassis.

TroubleShooting

If your ampliﬁ er does not appear to be working, check the obvious things ﬁ rst such as blown fuses, poor

or incorrect wiring connections, incorrect setting of crossover switch and gain controls, etc. There is

an illuminated red badge on top of the ampliﬁ er denoting the power state of the amp in addition to the

Protection LED on the end panel of your Kicker ZX series ampliﬁ er. When the red badge is lit this indicates

RED Badge Light 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. 5) Check

for blown fuses.

RED Badge Light 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 ampliﬁ er with the VOM meter set to measure "AC" voltage.

End Panel LED ﬂ ashing with loud music? The yellow LED indicates low battery voltage. Check all

the connections in your vehicle's charging system. It may be necessary to replace or charge your vehicle's

battery or replace your vehicle's alternator.

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)

control from left to right. If there is more bass output when turned to either side, then check your 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.

Ground Noise?

If you are using only one pair of RCA inputs, connect the RCA cable to the AMP1

inputs. Kicker ampliﬁ ers are engineered to be fully compatible with all manufacturers' head units. Some

head units may require additional grounding to prevent noise from entering the audio signal.If you are

experiencing this problem with your head unit, in most cases running a ground wire from the RCA outputs

on the head unit to the chassis will remedy this issue.

No Fader?

When using both sets of low-level (RCA) or high-level (speaker wire) inputs, the fader

button must be pushed in.

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 ampliﬁ er 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 ampliﬁ er wire the speakers in series. This will improve the sound quality, lower the total harmonic

distortion and lessen the thermal load at the ampliﬁ er. This may prevent an ampliﬁ er from shutting down, due to over-

current protection circuitry.

CAUTION: When jump starting the vehicle, be sure that connections made with jumper cables are correct. Improper

connections can result in blown ampliﬁ er fuses as well as the failure of other critical systems in the vehicle.
