ORED
Badge Light 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 amplifier with the VOM meter set to measure "AC"
voltage.
OEnd
Panel LED flashing 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.
OEnd
Panel LED on, no output?
1)
Amplifier
is
very hot.
c:>
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.
2)
Amplifier shuts down only while vehicle
is
running.
c:>Voltage
protection circuitry
is
engaged. Voltage to the amplifier
is
not within the 9-16 volt operating range. Have
the vehicle's charging and electrical system inspected.
3)
Amplifier will only play
at
low volume levels.
c:>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.
ONo
or
Low Output?
1)
Check the balance and fader control on source unit
2)
Check the RCA (or
speaker input) and speaker output connections 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.
OReduced
Bass Response? Check system phasing by reversing a speaker connection from positive to
negative on the stereo/subwoofer channel(s);
if
the bass improves, the speaker was out of phase.
OAlternator 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.
OGround Noise?
c:>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.
