Installation Warnings and Tips:
• Disconnect the negative (–) lead from your vehicle’s
battery.
• At the installation sites, locate and make a note of 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.

0Speaker Output Connectors
• Connect the speakers to these terminals, observing
proper polarity. Gold screws indicate +,and silver
screws indicate – .
• Five-channel operation: Connect the front left
speaker to the Front L+ and L– terminals and
the front right speaker to the Front R+ and R–
terminals.Repeat for the rear speakers, using
the Rear L+ and L– terminals,and the Rear R+
and R– terminals.Connect the subwoofer to the
Sub+ and Sub– terminals.
• Four-channel operation: Connect the stereo speakers
to the Front terminals, as above.The single speaker,
into which the amplifier’s rear channels will be
bridged, must be connected to the Rear terminals
marked “B.” Connect the subwoofer to the Sub+ and
Sub– terminals.
• Three-channel (bridged) operation: Connect one
speaker to the Front terminals marked“B.” Connect
the other speaker to the Rear terminals marked “B.”
Connect the subwoofer to the Sub+ and Sub–
terminals.
• Minimum speaker impedance for stereo operation is
2 ohms. Minimum speaker impedance for bridged
operation is 4 ohms. Minimum subwoofer impedance
is 2 ohms.
1Fuses
• Replace only with the same type and rating.
2Power Input Connectors
• +12V: Connect to the positive terminal of the vehicle’s
battery. 4 AWG wire is recommended. Install an
appropriate fuse holder and fuse (80A minimum) within
18' 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 illustration below.
4 AWG Adapter
• For power wire longer than 4' (1.2m), 4 AWG wire is
recommended. Use the adapter to make the connection
according to the illustration below.
3Protect 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
present in the amplifier’s output).
4Power On LEDs
• Illuminated when the amplifier is on.
5Subwoofer Low-Pass Filter
Frequency Control
• 12dB/Octave low-pass filter, variable from
32Hz to 320Hz.
• See Jfor the adjustment procedure.
6Subwoofer Input-Level Control
• Used to match the SUB input of the amplifier to the
output of the source unit.
• See Jfor the adjustment procedure.
7Rear Input-Level Control
• Used to match the rear input level of the
amplifier to the output level of the source unit.
• See Jfor the adjustment procedure.
8Front Input-Level Control
• Used to match the input level of the amplifier to
the output level of the source unit. See Jfor the
adjustment procedure.
9Front Crossover-Frequency Control
• 12dB/Octave crossover, variable from 32Hz to 320Hz.
ARear Crossover-Frequency Control
• 12dB/Octave crossover, variable from 32Hz to 320Hz.
See Jfor the adjustment procedure.
BDBO: Variable Subsonic High-Pass
Filter With Variable Boost (Q)
• For woofers in tuned (vented) enclosures, set
the frequency control to a value 10Hz below the
enclosure’s resonance (tuned) frequency.
• For woofers in sealed boxes, set the frequency control
to any value you prefer between 30Hz and 50Hz.
• Set the Boost control according to your preference,
being careful not to apply enough boost to damage
your woofer(s).
ABoost (Q) control provides up to 12dB of boost,
slightly above the high-pass filter’s frequency.
See Bfor appropriate settings.
BHigh-Pass Filter Frequency control, variable
between 10Hz and 80Hz.See Bfor appropriate
settings.
CRear Crossover-Filter Selector
• LP: Select for subwoofer(s) or to provide a low-pass
filter for separate mid-bass speakers.The subsonic
filter will provide a high-pass filter for separate
mid-bass speakers.
• FLAT: Select for full-range speakers when
no subwoofer will be used in the system.
• HP: Select for midrange speakers or full-range
speakers when a subwoofer is used in the system.
DFront Crossover-Filter Selector
• LP: Select for subwoofer(s).
• FLAT: Select for full-range speakers when no
subwoofer will be used in the system.
• HP: Select for midrange speakers or full-range
speakers when a subwoofer is used in the system.
EInput Selection Switch
• If you are using RCA-type inputs and the source unit
has a subwoofer output, and you have connected it to
the SUB input, set this switch to the EXT position.
Otherwise, set it in the INT position.
FSubwoofer Input Connector (RCA)
• Connect to subwoofer RCA-type outputs from the
source unit or signal processor.
GRear Input Connectors (RCA)
• Connect to rear RCA outputs from the source unit,
or signal processor.
HFront Input Connectors (RCA)
• Connect to front RCA outputs from the source unit
or signal processor.
IRear Input Signal Selection Switch
• If your source unit has only front RCA-type outputs
and they are connected to the amplifier’s Front input
connectors, move this switch to the FRONT setting.
If your source unit has 4 RCA-type outputs, leave it
in the 4CH position.
JSetting Gain (Input Level)
ATurn all Gain controls counterclockwise to
6V (minimum).
BWith a dynamic music track playing, turn the head
unit’s volume control to the 3/4 position.
CTurn Front Gain control clockwise until the music is
so loud that it no longer sounds clear (distortion is
present in the output).
DTurn Front Gain control counterclockwise gradually,
just until the music sounds clear, once again.
EFront Gain is now adjusted correctly.
FAdjust Rear- and Sub-Gain controls so that the level
of the rear speakers is proportionate to the level of
the front speakers, according to your preference.
