Operation
1. Crossover Switch Use the XOVER switch on the end panel of the amplifi er to set the internal
crossover to OFF, HI or LO. 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 fi xed at 100 Hz
with an 18 db/octave slope. Set the switch to LO if you want the amplifi er's internal crossover to serve as
a low-pass fi lter fi xed at 80 Hz with an 18 db/octave slope to power your subwoofers.
2. 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.
3. Fader Control With the amplifi er and source unit wired in the stereo operation confi guration shown in
Figure 1, set the fader button to the "On" postion to allow front and rear fade capability.
4. Bass Boost Turn the bass boost on to increase bass by 9db at 40 Hz. If you choose to enable the
bass boost it may be necessary to reduce the input gain control on the amplifi er to avoid clipping.
5. Automatic Turn-On Selection The DX 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.
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
a Power Protection LED on the side power panel of your Kicker DX series amplifi er. Depending on the
state of the amplifi er and the vehicle's charging system, the LED will glow either Red, Yellow or Green.
When the green LED is lit this indicates the amplifi er is turned on and no trouble exists.
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. 5) Check for
blown fuses
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 amplifi er with the VOM meter set to measure "AC" voltage.
Yellow 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.
Red LED on, no output? 1) Amplifi er is very hot.
impedance at the speaker terminals with a VOM meter (see the diagrams in this manual for minimum
recommended impedance and multiple speaker wiring suggestions). Also check for adequate airfl ow
around the amplifi er. 2) Amplifi er shuts down only while vehicle is running.
is engaged. Voltage to the amplifi er is not within the 9-16 volt operating range. Have the vehicle's
charging and electrical system inspected. 3) Amplifi er will only play at low volume levels.
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.

Short circuit
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.
Poor stereo image or reduced bass response?
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-Loop Noise? If you are using only one pair of RCA inputs, connect the RCA cable to the
AMP 1 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.

Dealer where you made your purchase. For more advice on installation, click on the SUPPORT tab on the Kicker

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.
