INPUT
Connect preamp signal cables from the head unit to these terminals.
CROSSOVER FREQUENCY
Controls the lowpass crossover point for the speaker outputs.
BASS BOOST
Variable bass boost from 0 to +18dB @ 45Hz.
REMOTE LEVEL CONTROL
This port is for connecting the subwoofer remote level control. This allows
up to 20dB of volume adjustment. This is not a bass boost, it controls the
level of the low pass signal.
NOTE: This control is not compatible with the Phoenix Gold LPL44 level
control.
SENS
Used to reach maximum amplier power with a wide variety of headunits.
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 switched +12V, usually a trigger wire coming
from the head unit or ignition.
GROUND
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 amplier to speakers. SD600.1 minimum impedance
is 1 ohm. SD300.1 minimum impedance is 2 ohm.
