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
PX
series
amplifier.
Depending
on
the state of the
amplifier
and the
vehicle's
charging system, the
LED
will
glow
either
Red
or
Blue.
When the
blue
LED
is
lit
this indicates
the
amplifier
is
turned on and no
trouble exists.
Blue LED off,
no
output?
With a Volt Ohm
Meter
(VOM)
check the
following:
0+
12
volt power
terminal
(should read + 12V
to+
16V)
f)
Remote turn-on
terminal (should
read + 12V
to+
16V)
C)
Check for reversed
power and ground connections
0
Ground
terminal, for proper conductivity.
Blue 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
f)
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.
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.
