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
LED
Will
glow either Red 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) @Remote turn-on terminal (should read + 12V to +
16V)
C)Check
for reversed
power and ground connections G)Ground terminal, for proper conductivity.
Green LED on, no output? Check the following:
ORCA
connections @Test speaker outputs with a
"known" good speaker.
C) Substitute source unit with a "known" good source unit.
0Check
for a signal
in
the
RCA cable feeding the amplifier with the VOM meter set to measure "AC" voltage.
Protection LED flashing with loud music? The red
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.
Protection LED on, no output?
0Amplifier
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. @Amplifier 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?
0Check
the balance control on source unit
@Check
the RCA
(or
speaker input) and
speaker output connections.
Alternator noise-whining sound with engine's RPM?
0Check
for damaged RCA
(or
speaker input) cable
@Check
the routing of RCA
(or
speaker input) cable C) Check the source unit for proper grounding
0Check
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.
