ONo
output from one channel?
1)
Check the balance control on source unit
2)
Check the RCA (or
speaker input) and speaker output connections for the channel
3)
Swap the RCA
(or
speaker input)
cable from left to right. If the problem changes sides then you have a bad RCA (or speaker input) cable
or source unit problem.
4)
Swap the speaker output wire from left to right.
If
the problem changes sides
then you have a bad speaker cable, passive crossover network and/or speaker.
o 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.
OPoor
stereo image
or
reduced bass response?
C::>Check
system phasing by turning the balance
control from left
to
right.
If
there
is
more bass output when turned
to
either side, then check your speaker
wiring, passive crossover networks and speaker terminals for proper positive and negative connections.
Reverse a speaker connection from positive
to
negative on the stereo/subwoofer channel(s);
if
the bass
improves, the speaker was out of phase.
o Ground-Loop Noise?
c::>lf
you
are
using only one pair
of
RCA inputs, connect the RCA cable
to
the
AMP 1 inputs.
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.

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.
