AUX OUTPUT
B
B
Used to reach maximum
amplifier power with a wide
variety of headunits. The
amplifier is more sensitive
to input signals when set
to .2 and less sensitive
when set to 8.
INPUT SENSITIVITY
Controls the low pass cross-
over point for the speaker
outputs. This eliminates high
frequencies from reaching
the subwoofers. The cross-
over frequency is adjustable
from 40Hz to 400Hz with a
24dB per octave slope. The
lowpass potentiometer has
41 detents see the chart
to set the exact crossover
frequency desired.
LOWPASS CROSSOVER
Controls the high pass cross-
over point for the speaker
outputs. This eliminates low
frequencies from reaching
the speakers. The crossover
frequency is adjustable from
40Hz to 400Hz with a 24dB
per octave slope. The lowpass
potentiometer has 41
detents see the chart to
set the exact crossover
frequency desired.
HIGHPASS CROSSOVE
R
TWIN-T BASS EQ
Allows for up to 18dB of
boost at 45Hz for the speaker
outputs when turned clock-
wise. It cannot affect the
auxiliary outputs. Use this
control sparingly. Every 3dB
of boost requires double the
power at 45Hz.
CROSSOVER ON
When the push button is
set to IN the crossover is
on. When set to the OUT
position the crossover is off.
Note: That the high and low
pass buttons are seperate
and when both are set to
the ON position a bandpass
filter is created for that set
of channels.
B+ R B–
B+
This must be connected
to fused the positive terminal
(+12V) of the car’s battery.

4 Gauge
REMOTE
This must be
connected to sw12V,
usually a trigger wire coming
from the head unit or ignition.
B–
This must be connected
to the negative terminal
(–12V) of the car’s battery.

AUX OUTPUT
Provides a full range signal
for an additional amplifier.
LPL44 PORT
This port is for connecting
the optional LPL44
™
Remote Lowpass Level
Control knob allowing up
to 20dB of volume adjust-
ment. The LPL44 will only
work when the lowpass
crossover is on.
STATUS LED
Blue LED lights to indicate
the amplifier is on. The LED
will blink in 1 second inter-
vals if the amplifier goes
into protection mode. This
usually means the amplifier
is in need of service or a
grounded speaker wire is
present in the system.
