Precautions: Read First!

If after reading the direction you feel uncomfortable about installing the amplifier in your car, or not

equipped or competent to do so, you should have the amplifier installed by an authorized installer.
It's your car!

Negative battery terminal must be disconnected before any electrical connections are made.
Be sure choosing a location that provides substantial ventilation for the amplifier.
The most preferred locations would be in your car's trunk, under the front seats or on the back wall of

a truck.

The location chosen should provide at least 2" of clearance above the amplifier for adequate

ventilation.

If the amplifier is to be mounted vertically be sure that it is in a place where adequate air will flow

along the length of its heat sink fins for cooling.

NEVER mount the amplifier up side down; this will cause the heat to rise back into the amplifier

causing thermal shutdown or possible permanent damage.

NEVER mount the amplifier in a location that is subject to direct sunlight or exposed to moisture.
Be sure to mount the amplifier to a strong, solid surface, which will not give way under the stress of a

sudden stop or accident.

Make sure that the mounting screws will not penetrate the gas tank, brake and fuel lines, wiring or

other critical parts of your car when installed.

NEVER operate the amplifier without the proper power and ground wire 10 gauge minimum.
NEVER operate the amplifier without proper fusing. Fuse holder must be located with in 0.5 meters

from the battery. This fuse is to protect the car not the electronics. In case of a short, the fuse will
blow instead of the wire burning up. Using other than the recommended fuse ratings at the battery
and at the amplifier may cause damage to the amplifier and will void your warranty.

Do not run wiring underneath or outside the car since exposure to the elements may cause the

insulation to deteriorate rapidly, resulting in short-circuits and/or intermittent operation. All cables
should be run beneath carpets and inside trim pieces.

To help minimize interference, it is best to run the power cables along the opposite side from the

audio cables.

Whenever wires pass through metal, rubber or plastic grommets must be used to prevent the mental

from wearing through the installation and causing a short.

Whenever possible, use cable ties, mounting clamps and similar wiring aids (available from an

electrical supply or auto parts store) Adding stress relief loops to wiring is also advisable to prevent
straining or breakage.

It is best to test the system before the amplifier is mounted and interior of car is reassembled.
If the temperature inside your car reaches extreme levels (such as sitting locked up for several hours

in the hot sun or exposed to a very cold winter's day) the amplifier may go into protection mode and
shut off. Leave the unit off until the ambient temperature returns to normal.

The amplifier operates with any vehicle using a 12-volt negative ground system. If you are not sure

of the type of electrical system in your vehicle, consult your authorized dealer or qualified mechanic.

NEVER ground the speaker leads and NEVER allow the speaker leads to come in contact with each

other. Speaker wire should be 18 gauge or larger.

Remote turn on wire must be switched by the radio does not have a remote turn on or antenna

output, connect to wire that has a positive 12 volts when the key is turned to the accessory. If the
amplifier does not turn off the battery will die.

Do not listen to high volumes for extended periods of time or hearing damage may occur.

CONTINOUS EXPOSURE TO SOUND PRESSURE LEVELS OVER 100dB

MAY CAUSE PERMANENT HEARING LOSS. HIGH POWERED AUTOSOUND

SYSTEM MAY PRODUCE SOUND PRESSURE LEVELS WELL OVER

130dB. USE COMMON SENSE AND PRACTICE SAFE SOUND.

Installation

MOUNTING:

1. After reading precaution, decide where you are going to install the unit. Also, see the picture below.

2. Once the location has been determined, remove the plastic decorative panels from left and right sides
of amplifier then place the amplifier in position. Using a felt tip pen or pencil mark the four holes to be
drilled for mounting. NEVER use the amplifier as a template for drilling. It is very easy to damage the
amplifier surface in manner.

3. Remove amplifier with a getting back the plastic panels. Drill four 3.5 mm. Diameter holes into
mounting surface on steel panel. If you want mounting the MDF or wood panel, drill four 3.0m/m
diameter holes into mounting surface.

4. If possible, test the system operating before final mounting of the amplifier.

5. Mount the amplifier using the supplied 4 self-threading screws.

Connections

POWER SUPPLY AND REMOTE TURN-ON OF THE AMPLIFIER
NOTE: Do not connect the plus terminals to the car battery before other connections, or it may occur

short circuit.
The gauges of power cables should be enough for the power amplifier demands at least 5.27mm2.
The + 12V DC and ground cables should be at least 6 mm2.
Firstly connect the GROUND terminal to the battery negative pole. It is very important that the
connection is fastened. Loose connection may cause malfunctions or interference noise or distortion. Dirt
residues must be carefully removed from the battery connection point.
Then connect the +12V DC power terminal via an integrated fuse to the battery plus pole. The fuse must
be located close to the battery; the length of cable from the battery positive pole to the fuse must be
50cm for safety. Install the fuse after other connections including the connection of the stereo and the
loudspeakers. Finally connect the terminal of the remote turn-on to the amplifier REM control jack. The
cable gauge of 0.75mm2 is sufficient for the amplifier REMOTE connection.

AUDIO CABLES

When installing the stereo input connection and the speaker connection, make sure the audio and the

power supply cables do not run the same side of the vehicle. This reduces crosstalk interference to the
audio cables.

LOUDSPEAKER CONNECTIONS

In normal operation mode (I.e. one loudspeaker on each Individual amplifier channel), the lowest

terminal Resistance is 2 Ohms per channel.

In bridge mode (two amplifier outputs combined), the lowest terminal resistance is 4 Ohms.
Never connect the loudspeaker negative terminals to the vehicle chassis.
Do not connect the +12V power supply to a loudspeaker output otherwise this will destroy the

amplifier terminals.

Operation elements

SETTING THE INPUT AND SENSITIVITY

The regulator for input sensitivity is used to adapt amplifier for each car radio or tape deck. Turn the
volume control of your radio to central position and adjust the input-level control (2) Fig. 5, to produce
medium volume. This setting can provide sufficient power and optimum Signal to Noise (S/N) ratio.
CAUTION: Do not run the amplifier in high volume for long time, otherwise the loudspeakers will be
damaged.

LOW-PASS FILTER WITH ADJUSTABLE CROSSOVER FREQUENCY

If the unit is used as a subwoofer amplifier, turn the switch (4) to" LPF". And set proper cross-over
frequency with adjusting the control (5) to make the filter match the timbre requirement of the installed
woofer.
The crossover slope of the filter can accurately reduce the medium and high frequency ranges.

HIGH-PASS FILTER WITH ADJUSTABLE CROSS-OVER FREQUENCY

If the amplifier is used for satellite loudspeakers (mid-range/tweeter loudspeakers), turn switch (4) to
"HPF".
Set proper crossover frequency with adjusting the control (3). The frequencies only above the setting
will be amplified. This can effectively minimizes distortions caused by excessive membrane movement at
the low frequencies. And the result does not reduce the bass level when it is used for small power-supply
loudspeakers.

BASS-BOOST

Use the bass-boost switch (6) to eliminate harmonic distortion of the lower bass frequencies and weaken
the bass faction.

OUTPUTS FOR CONNECTING ADDITIONAL AMPLIFIERS

The input signal of the LOW INPUT connections L and R is directly output to the LINE OUT L and R jacks
(1).
Additional amplifiers can be connected to the LINE OUT jacks without additional T-plugs and cables.

Power supply/remote turn-on connection

(1) Terminal for +12V battery voltage
(2) REM terminal for remote turn-on
(3) GND terminal for the ground, to the battery negative pole
(4) Battery
(5) Automatic antenna connection,
If your car is not equipped with an automatic antenna connection, connect this cable plus pole (+) to the
ignition lock. An on/off switch should be inserted in this case. Make sure that this switch is turned off if
the amplifier is not used.
