INPUT
Connect preamp signal cables from the head unit to
these terminals.
GAIN
Used to reach maximum amplifier power with a wide
variety of headunits.
PHASE
Switches the output signal 180°.
SUBSONIC
Controls the highpass crossover point for the speaker outputs to
eliminate extreme low frequencies.
FREQ
Controls the lowpass crossover point for the
speaker outputs.
BASS BOOST
Variable bass boost from 0 to +12dB @ 45 Hz.
LPF
Variable bass boost from 0 to +12dB @ 45 Hz.
POWER/PROTECT

SPEAKER OUTPUTS
Used to connect the amplifier to speakers. SM600.1 minimum
impedance of 2 ohm.
REMOTE
This port is for connecting the optional remote level control
(XMRB1). This allows up to 20dB of volume adjustment. This is
not a bass boost, it controls the level of the low pass signal.
FUSE
This amplifier requires three 40A fuses.
12V+
This must be connected to the fused positive terminal (+12V) of
the car’s battery.
REMOTE
This must be connected to sw12V, usually a trigger wire
coming from the head unit or ignition.
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.
