TROUBLESHOOTING
If
your amplifier
does not appear to be working , check the obvio
us
things first such
as
blown
fuses, poor or
in
correct 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 or Green. When the green
LEO
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)
@Check
for reversed
power and ground connections
0Ground
terminal,
for proper conductivity.
Green LED on, no output?
Check the
following:
ORCA
connections
@Test
speaker outputs with a
"known"
good speaker.
@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.
@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
@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.
