all fuel lines, hydraulic brake lines, vacuum lines
and electrical wiring. Use extreme caution when
cutting or drilling in and around these areas.
• Choose a safe mounting location away from moisture.
• Make sure there is sufficient air circulation at the
mounting location for the amplifier to cool itself.
• Mount the amplifier, using the supplied hardware.

0
Speaker Output Connectors
• Connect the subwoofer to these terminals,
observing proper polarity. Either + or –
terminal may be used. Minimum total
impedance is 1 ohm.
1
Fuses
• Replace only with the same type and rating.
2
Power Input Connectors
• +12V: Connect to the positive terminal of the
vehicle’s battery. 8 AWG wire is recommended.
Install an appropriate fuse holder and fuse (40A
minimum) within 18 inches of the battery. Make
sure the wire is not damaged or pinched during
installation. Install protective grommets when
routing wires through the firewall or other sheet
metal.
• GND: Connect to the vehicle’s chassis. Refer to
the picture below.
• REM: Connect to the “Remote Out” lead from the
source unit or to a source of switched
+12V (ACC).
3
Aux Output Connectors (RCA)
• Nonfiltered pass-through output. Connect to
the input of an additional amplifier.
4
Input Connectors (RCA)
• Connect to the RCA outputs from the source unit
or signal processor.
5
Input-Level Control
• Used to match the input level of the amplifier
to the output level of the source unit.
• See 9for the adjustment procedure.
6
Protect LED
• Illuminated under any of the following fault
conditions: battery over/under voltage, short
circuit in speaker wires, amplifier is too hot,
amplifier’s output circuit has failed (DC voltage is
present in the amplifier’s output).
7
Low-Pass Filter Frequency Control
• 12dB/octave low-pass filter,
variable from 32Hz to 320Hz.
• See Afor the adjustment procedure.
8
Power On LED
• Illuminated when the amplifier is on.
9
Setting Input Level
A Turn Input Level control counterclockwise to
6V (minimim).
B With a dynamic music track playing, turn the
head unit’s volume control to the 3/4 position.
C Turn Input Level control clockwise until the
bass output is proportionate to the output of
the high-frequency speakers, according to
your preference.
D Input level is now adjusted correctly.
A
Setting the Crossover
A Crossover setting for subwoofers.
Note: Acceptable frequency ranges are indicated
in gray.
This product is designed for mobile applications and is not
