Before making any electrical connections, make sure that
you disconnect the battery’s ground cable to prevent the possibility of
short circuits or damage to your electronic equipment. If your vehicle’s
stereo (head unit) comes with an Anti-theft code, DO NOT disconnect
the battery. If you have the access code for the stereo (head unit),
please refer to the vehicle’s owner’s manual.

Before beginning the installation, consider the following:
A. If you plan to expand your system by adding other components sometimes in
the future, ensure that adequate is left, and cooling requirements are met.
B. Are your components matched? The peak power rating of your speakers
must be equal or greater than the amplifier’s. They also must be 2-8 ohms im-
pedance (This information is normally printed on the speaker magnet).
C. Consider the length of your leads which should not be too long or short when
determining the mounting location. Pre-Amp input jacks require a length of high
quality shielded male to male RCA patch cord.

Mounting Your Amplifier
The mounting position of your amplifier will have a greater affect on its ability to
dissipate the heat generated during normal operation. This amplifier has ample
heat sink for heat dissipation, and is designed with a thermal shutdown circuit
(for heat protection). DO NOT enclose the amplifier in a small box or cover it so
that air is not able to flow freely.

Temperatures in car trunks have been measured as high as (155 F) in the sum-
mer time. As the thermal shut down point for the amplifier is (185 F), it is easy
to see that it must be mounted in an area that provides for maximum cooling
capability. To achieve maximum advantage of convection air flow in an enclosed
trunk, mount the amplifier in a horizontal position.

Cooling requirements are considerably relaxed when the mounting inside the
passenger compartment since the driver compartment will not allow tempera-
tures to reach a critical point. Floor mounting under the seat is usually satisfac-
tory as long as there is at least 1 inch of clearance above the amplifier’s heat
sink for ventilation.
A. Select a suitable location that is convenient for mounting, is accessible for
wiring, and has ample room for air circulation and cooling.
B. Use the amplifier as a template to mark the mounting holes. Remove the am-
plifier and drill holes. Use extreme caution, inspect underneath surface before
drilling!
C. Secure the amplifier using the screws provided.
Caution: Before connecting any wires to the amplifier, discon-
nect the ground lead from the battery. Leave the ground lead
disconnected until you are done wiring the amplifier.

Turning On The Amplifier
A

J
U
S
T
I
N
G
The amplifier automatically turns on a few seconds after you turn vehicle’s igni-
tion switch to ACC ON or turn on your auto sound system, depending upon how
you wired the system. The POWER indicator on the top of the amplifier illumi-
nates when the amplifier is on.
Important: Your amplifier requires 90 amps or more of power from your vehicle’s
battery during operation. To protect your battery from your battery from dis-
charging, do not operate the amplifier unless your vehicle us running.
Adjusting The Audio Level (“Gain Matching”) By Ear
&
T
U
N
I
N
G
For best performance, you must match the amplifier’s input sensitivity to your
source unit’s maximum output level. The GAIN CONTROL (MIN / MAX) located
on the side of the amplifier is designed to do this. It is Not a volume control. It
adjusts the incoming signal level so that the source unit and amplifier reach
maximum output at the same time. This assures that maximum system is
achieved with minimal distortion.
1. Turn the GAIN CONTROL (MIN / MAX) fully counterclockwise to MIN.
2. Play full frequency music that has continuous high levels (FM pop music is a
good choice).
3. Turn up the source unit’s volume control until just before you hear the source
unit’s distortion or 90% of full output (which ever comes first).
4. SLOWLY turn the GAIN CONTROL clockwise until just before you hear
amplifier or speaker distortion, until you reach a maximum comfortable listening
level (which ever come first).
5. Turn the source unit’s volume control back to a desire comfortable listening
level and enjoy.
FREQUENCY RESPONSE

@45Hz
FREQENCY (Hz)
The BASS BOOST CONTROL raises the amplifier output up to 18db at fre-
quencies tightly centered around 45 Hz. This “bump” can have a dramatic affect
on the bass system’s apparent volume. Use caution (!) when adjusting this
control as serious subwoofer damage may result from overpowering or overex-
cursion.

Investigate the layout of your vehicle thoroughly before
drilling or cutting. Take care when you work near the gas tank,
gas lines, hydraulic lines, electrical components and electrical
wiring. Do not use the equipment unmounted. Attach this sys-
tem securely to prevent damage, particularly in the event of an
accident or aggressive driving. Do not mount the system so that
wire connections are unprotected or are subjected to pinching
or damage from nearby objects. Before connecting or discon-
necting power connections at the system power terminals, dis-
connect the +12V DC wire at the battery end. Confirm that your
source unit and other equipment are turned off while connecting
the input terminals. If you need to replace the power fuse, re-
place it only with a fuse identical to the provided fuse. Using a
fuse of different type or rating may result in damage to the sys-
tem, which is not covered by the manufacturer’s warranty. Do
not install any product where it may be subjected to excessive
heat, moisture and dust or where it may be repeatedly kicked,
brushed or bumped. Make absolutely sure that the terminals
for the products are connected to the proper inputs and outputs
from the music source. Never run the wiring on the outside of
the vehicle or under it where it can be damaged by road hazards
or any moving parts of the vehicle. Use existing wire channels,
sills, panels and molding strips inside the vehicle to hide the wir-
ing for safety and a neat appearance.
