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 amplifier to speakers. Front and Rear Channel minimum
impedance is 4 ohms bridged or 2 ohms stereo. Subwoofer channel minimum
impedance is 2 ohms. Use Right + and Left - to bridge the front or rear channels,
the subwoofer channel is not bridgeable.
FRONT, REAR AND SUB INPUTS
Connect preamp signal cables from headunit to these inputs. The front
AND rear inputs must be used, if only the front input is used then the rear
speaker outputs will have no output signal. The Sub Input may or may not
be used see SUB INPUT SWITCH for more information.
HPF AND LPF CROSSOVER FREQUENCY
Controls the crossover point for the speaker outputs.
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 subwoofer channel only.
NOTE: This control is not compatible with the Phoenix Gold LPL44 level
control.
BASS BOOST
Variable bass boost from 0 to +18dB @ 45Hz for the subwoofer channel only.
SENS
Used to reach maximum amplifier power with a wide variety of headunits.
SUB INPUT SWITCH
IN: Subwoofer speaker output is fed by the sub Input. If the headunit or
processor has a subwoofer low level output use this setting.
OUT: Subwoofer speaker output is fed by the front input and the sub Input is not
used. If the headunit or processor only has front and rear low level outputs use
this setting.
RMD
