2.1 INPUTS + OUTPUTS
1 RCA INPUTS 1/2-CH
Low-level stereo RCA signal input 1/2-CH for connection to head-unit.
2 HIGH INPUT
Molex connector terminal to insert the High level adapter (4-Pin) that picks up the
amplified speaker signal from the head unit’s front output (if head unit does not
feature dedicated RCA line outs).
3 SPEAKER OUTPUT TERMINAL
Output terminal to connect the speakers to the amplifier in either stereo or bridged
mode. For bridge connection, use the terminals with fat polarity signs.
4 ATC FUSE HOLDER
Fuse holder for 1 x 25 A ATC fuse. Never deploy fuses of higher amperage rating.
5 “+12 V” POWER INPUT TERMINAL
Terminal to connect the amplifier to the positive +12 V pole of the car battery.
6 “REM” INPUT TERMINAL
Terminal to connect the amplifier to the automatic (remote) turn-on / turn-off lead of

unit to the amplifier’s input.
2 OPERATION MODE SWITCH 1/2-CH
Slide switch to select the operation mode of the X-over for section 1/2-CH of the
amplifier.
3 X-OVER FREQUENCY CONTROL 1/2-CH
Control potentiometer to adjust the highpass or lowpass filtering frequency point for
section 1/2-CH of the amplifier.
4 SUBSONIC HIGHPASS FREQUENCY CONTROL 1/2-CH
Control potentiometer to adjust the subsonic highpass filtering frequency point for
section 1/2-CH of the amplifier.
5 PHASE SWITCH 1/2-CH
