Operation
Your Kicker
MX.5
series amplifier has seven rotary controls and
two
switches on the
top
panel. Before turning on the
system for the first time, remove the sealed
top
panel (protects the controls from water damage) by removing the
two
phillips screws.
See
Figure
1.
Then turn the seven rotary controls on the
top
of
the amplifier
to
the full counter-
clockwise position.
1.
CrossoverSwitch
The crossover switches on the
top
panel are for setting the internal crossovers for
the
"full-range" audio channels (12dB slope
per
octave).
In
the OFF position the amplifier passes a full-range signal
to
the
speakers. The HI
position
should be selected when connected
to
speakers, which you
do
not want
to
receive any
sub-bass
information. Never change the crossover "OFF/HI" switch setting with the audio system on!
2.
InputGainControl
The input gain control
is
not a volume control. It matches the
output
of
the source unit
to
the
input level
of
the
amplifier. Turn the source unit
up
to
about
3/4
volume
(if
the source unit goes
to
3D,
turn
it
to
25).
Next, slowly turn (clockwise) the gain on
the
amplifier
up
until you can hear audible distortion, then turn it
down
a little.
Adjust
AMP
1,
then
proceed
to
AMP 2 and finally the Subwoofer Channel input gain control.
3.
BassBoostControl
The bass boost control is designed
to
give you increased output 0 - 18dB at
40
Hz. The
setting for this
control
is
subjective. If you
turn
it up, you must
go
back and adjust the input gain control
to
avoid
clipping
the
amplifier.
4.
CrossoverControl
The setting for this control
is
subjective; 80Hz is a
good
place
to
start.
5.
RemoteBass(Level
Control}
When using the remote bass level control you have the ability to control
the
level of
the
Subwoofer
Channel's
output remotely.
To
mount
the remote bass level control, simply screw the metal
bracket
to
the chosen location. Then slide the housing onto the bracket until it snaps into place. Run the cable from
the
controller
to
the
"Remote
Bass"
jack
on the amplifier chassis.

Modern
high
performance
coaxial and
component
speakers have a lower DC Resistance than what used
to
be
available. The
Kicker
speakers are rated at four ohms and
work
with any source unit
or
amplifier designed
to
operate
at a four
ohm
load. If you want
to
use
two
Kicker coax
or
component speakers on each channel of your amplifier wire
the
speakers
in
series, as shown
in
Figure 4. This will improve the sound quality, lower the total harmonic distortion
and lessen
the
thermal load at the source unit
or
amplifier. This may prevent an amplifier from shutting
down,
due
to
over-current
protection
circuitry.-
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 one LED on
the
top
of
your
Kicker
MX
series amplifier. When the LED
is
green this indicates the amplifier
is
turned on and no trouble exists. If the
LED
is
red, this indicates that the protection circuitry (SORT)
is
engaged.
o
LED
Green,
no
output?
With a Volt Ohm Meter (VOM) check the following:
1)
+12 volt power terminal (should
read
+
12V
to
+16V)
2)
Remote turn-on terminal (should read +12V
to
+16V)
3)
Check for reversed
power
and
ground
connections
4)
Ground terminal, for proper conductivity.
o
LED
Green,
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
"AC" test position selected on the VOM meter.
