Amplifier Owner’s Manual
INPUT
Connect preamp signal cables from the head unit to these terminals.
OUTPUT
Provides a full range signal for an additional amplifier. There is no signal
loss if using this output.
CROSSOVER FREQUENCY
Controls the lowpass crossover point for the speaker outputs.
BASS BOOST
Variable bass boost from 0 to +18dB @ 45 Hz.
LOW PASS LEVEL CONTROL (LPL)
This port is for connecting the optional remote level control (LPL44). This
allows up to 20dB of volume adjustment. This is not a bass boost, it
controls the level of the low pass signal.
REMOTE MONITORING DISPLAY (RMD)
Connect optional RMD Voltage Display to this port
LEVEL
Used to reach maximum amplifier power with a wide variety of headunits.
HI INPUT
Connect a factory system’s headunit or amplifier outputs. Using the HI level input the
amplifier will automatically turn on and off using the factory system’s audio signal as a
trigger. The high level auto on switch turns off the auto turn on function, but the high
level input still works as normal.
SUBSONIC CROSSOVER FREQUENCY
Controls the highpass crossover point for the speaker outputs to eliminate extreme
low frequencies.
12V+
This must be connected to the fused positive terminal (+12V) of the car’s
battery. The fuse must be located within 18 inches of the battery.
REMOTE
This must be connected to sw12V, usually a trigger wire coming
from the head unit or ignition. This is not used if using Hi input auto on
feature.
GND
This must be connected to the negative terminal of the car’s battery or
bolted to a clean, unpainted part of the chassis of the vehicle.
SPEAKER OUTPUTS
Used to connect the amplifier to speakers. R250.1 and R500.1 minimum
impedance is 2 ohm, R1000.1 is 1 ohm.
R1000.1 - R500.1 - R250.1
