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
is
a Power
Protection
LED
on
the side power panel of your Kicker
OX
series amplifier, Depending on the state of the amplifier
and the vehicle's charging system, the
LEO
will
glow either Red, Yellow or Green, When the green
LED
is
lit
this
indicates the amplifier
is
turned
on
and no trouble exists,
Green LED off, no output? With a
Volt
Ohm Meter
(VOM)
check the following:
0+12
volt power terminal
(should
read
+12V to +
16V)
8 Remote turn-on terminal (should read +12V to +
16V)
C)Check for reversed
power and ground connections
OGround
terminal, for proper conductivity.
Green LED on, no output? Check the following:
ORCA
connections
8Test
speaker outputs with a
"known" good speaker. C)Substitute source unit with a "known" good source unit.
OCheck
for a signal
in
the
RCA
cable feeding the amplifier with the VOM meter set to measure "AC" voltage.
Yellow LED on? 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? OAmplifier
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 recommended impedance
and multiple speaker wiring suggestions). Also check for adequate airflow around the amplifier,
8Amplifier
shuts down only while vehicle
is
running = voltage protection circuitry
is
engaged, Voltage to the amplifier
is
not
within the
10-16
volt operating range, Have the vehicle's charging and electrical system inspected, C)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?
OCheck
the balance control on source unit
8Check
the RCA (or speaker input) and
speaker output connections,
Alternator noise-whining sound with engine's RPM?
OCheck
for damaged RCA
(or
speaker input) cable
8Check
the routing of RCA
(or
speaker input) cable C)Check the source unit for proper grounding
OCheck
the gain settings and turn them down
if
they are set too high.
Reduced bass response? 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?
KICKER
amplifiers 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.
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 thermal load at the amplifier, This
may prevent
an
amplifier 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 amplifier fuses
as
well
as
the failure of other critical systems
in
the
vehicle.
