POWER PANEL
INPUT :
Used for connecting RCA preamp
signal cables from the source unit to
the amplifier.
PWR LED :
Indicates the amplifier is grounded,
and rec12V and REM power.
PRO LED :
Indicates a general malfunction due
to SPEAKER SHORT, THERMAL,
OVERLOAD, HI/LOW VOLTAGE,
DC OFFSET.
GAIN :
Matches the output voltage of the
source signal to the amplifier’s
input section.
SUBSONIC :
Controls the high pass cutoff point for
the speaker outputs. This helps to
eliminate extremely low frequencies
that can waste amplifier power and
cause damage to your subwoofers.
REMOTE :
This port is for connecting the remote
subwoofer control.
LPF :
Controls the low pass cutoff point for
the speaker outputs.
MAIN/STRAP :
This switch enables the STRAP mode
function when connecting two or more
DM SERIES amplifiers. (See Page 9
for STRAP mode connection).
IN :
Used when Strapping two DM
SERIES amplifiers. Connects to the
OUT RCA terminal.
OUT :
Used when Strapping two DM
SERIES amplifiers. Connects to the
IN RCA terminal.
GND :
Connect to a ground wire going
directly to the chassis of your
vehicle. Minimum cable size is
0 gauge.
REM :
Connect to a sw12V cable.
+12V :
Connect to a fused positive cable
(+12V) from the battery. Minimum
power cable size is 0 gauge.
SPEAKER OUTPUT TERMINALS :
Connect to the speaker's + and -
terminals. Minimum suggested
speaker cable size is 12–10 gauge.
DM SERIES amplifiers are monoblock
but have two + and two - terminals for
easier connection of multiple speaker
cables. Minimum impedance is 1 ohm.
