  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.

Speaker Output Connectors

• Connect the speakers to these terminals, 

observing proper polarity. or – 
terminal may be used. Minimum total 
impedance is 2 ohms.

1

Fuse 12V Connection

• Replace fuse only with the same type and rating.
• Mount the fuse holder within 18" (45cm) of the

vehicle’s battery, inside the engine compart-
ment, and connect one end of the fuse holder 
to the battery’s “+” terminal using a single piece
of 0-gauge (0 AWG, 53.5mm

2

) wire, as shown in

Figures 1 and 2. 

• For normal installation, connect two pieces of 

4-gauge (4 AWG, 22mm

2

) wire to the other end of

the fuse holder, as in Figure 1. Route both pieces
of 4-gauge (4 AWG, 22mm

2

) wire through the car,

using rubber grommets in all locations where
the wire must pass through metal. Connect the
other end of the 4-gauge (4 AWG, 22mm

2

) wire to

the two “+” terminals on the amplifier’s power
connectors 

2

(refer to illustrations page).

Figure 1.

• For competition installations, replace the fuse

with a 300A ANL (not included). Connect a single
piece of 0-gauge (0 AWG, 53.5mm

2

) wire to the

other end of the fuse holder, as in Figure 2.
Route the 0-gauge (0 AWG, 53.5mm

2

) wire

through the car, using rubber grommets in all
locations where the wire must pass through
metal. Connect the other end of the 0-gauge 
(0 AWG, 53.5mm

2

) wire to the input terminal of a

power distribution block (not included) designed
to accept 0-gauge (0 AWG, 53.5mm

2

) wire.

Connect two pieces of 4-gauge (4 AWG, 22mm

2

)

wire to the distribution block and connect the
other ends of the wire to the two “+” terminals
on the amplifier’s power connectors 

2

(refer to

illustrations page).

Power Input Connectors 

• +12V: See ”Fuse Holder“ 

1

.  

• GND: Connect to the vehicle’s chassis using 

4-gauge (4 AWG, 22mm

2

) wire. Refer to Figure 3. 

Figure 3.

• 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 

B

for the adjustment procedure.

6

Low-Pass Filter Frequency Control

• 12dB/octave low-pass filter, 

variable from 32Hz to 320Hz.

• See 

C

for the adjustment procedure.

7

DBO (Dynamic Bass Optimization) 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 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).

A

DBO High-Pass Filter Frequency control,
variable between 10Hz and 100Hz. See
above for appropriate settings. 

B

DBO Boost control provides up to 
12dB of boost, slightly above the high-
pass filter’s frequency. See above for 
appropriate settings.

8

Optional Remote Level Control (RLC) Connector 

• Connect the Remote Level Control (RLC) here,

using the RJ-11 cable (Supplied with RLC). 

9

Power On LED

• Illuminated when the amplifier is on.

A

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).

B

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.

C

Setting the Crossover

A

Crossover setting for subwoofers.

Note:

Acceptable frequency ranges are indicated 

in gray.

D

Remote Level Control (optional)

The Remote Level Control, if installed, will allow
you to adjust the level of bass while seated in the
listening position.
