eThe amplifier needs to be installed by an authorised installer
@Negative battery terminal must be disconnected before any electrical connections are made.
Be sure choose a location that provides substantial ventilation for the amplifier. The most
preferred locations would be in you car's trunk, under the front seats or on the back wall
of a truck.
The location chose should provide at least 2” of clearance above the amplifier for adequate
ventilation
@lf 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 heatsink 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, sold 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.
e Ensure that quality cabling be used to enhance the qualityand performance of your
amplifier
e Warranty maybe void if proper installation technique and cabling is not used.
10
@®NEVER operate the amplifier without the proper power and ground wire, 8 gauge minimum
for the 4 channel and 4g for the MONO (CLASS D) amplifier
@NEVER operate the amplifier without proper fusing. Fuse holder must be located with in
0.5 meters from the battery. This fuss is to protect the car not to electronics. In case ofa
short, the fuse will blow instead of the wire buring up. Using other than the recommended
fuse ratings at the battery and at the amplifier may case 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.
eTo 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 b used to prevent
the metal from wearing through the installation and causing a short.
@Whenever possible, use cable ties, mounting clamps and similar wiring ads. (Available
from an electrical supply or auto parts store) Adding stress relief loops to wiring is also
advisable to prevent straining or breakage.
@lt is best to test the system before the amplifier is mounted and interior of caris
reassembled
elfthe 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.
eNEVER ground the speaker leads and NEVER allow the speaker leads to come in contact
with each other. Speaker wire should be 18 gauge or large.
Do not listen to high volumes for extended periods of time or hearing damage may occur.
CAUTIONS EXPOSURE TO SOUND PRESSURE LEVELS OVER 100 dB MAY
CAUSE PERMANENT HEARING LOSS, HIGH POWERED AUTOSOUND SYSTEM
MAY PRODUCE SOUND PRESSURE LEVELS WELL OVER 130dB. USE COMMON
SENSE AND PRACTICE SAFE SOUND.
ADJUSTMENTS
1.Setto the “H.P.F” position when the amplifier is used to drive a tweeter/midrange system.
The frequencies below the crossover point will be attenuated at 12dB/octave. Permits
adjustment of the crossover frequency, by rotating the knob to select any frequency
between 120Hz to 3KHz as the crossover point.
2.Settothe “L.P.F” position when the amplifier is used to drive a subwoofer. The frequencies
above the crossover point will be attenuated at 12dB/octave. Permits adjustment of the
crossover frequency, by rotating the knob to select any frequency between 50Hz to 250Hz
as the crossover point.
3.Setto the “OFF” position when the amplifier will be used for driving full-range speakers.
The full frequency band width (20Hz-20KHz)will be output to the speakers without high
or low frequency attenuation.
4 Level adjustment The sensitivity adjustment is to allow the amplifier to work with many
different brands of head units. It allows input signal to vary between 350 millivolts to 5
volt from the heat unit or other signal processor. Star by setting the sensitivity adjustment
to the “MIN”(3 volts). Using a cassette or compact disc that you are familiar with , turn on
head unit to the 3/4 volume setting. Slowly turn up sensitivity adjustment towards the
“MAX”(200 millivots) using a flat head screw driver .Stop turning on the onset of distortion
and turn back just a slight. The 3/4 volume setting is now the “maximum” volume for the
head unit. The goal is to keep the level control to the lowest setting yet still have enough
signal to drive the amplifier. This is done to prevent over driving the amplifier and to keep
system noise to minimum. It is important no over drive speakers (at point of distortion)
this will cause permanent damage to speaker. Also, if the amplifier itself is over driven,
it could be damaged.
5.The “BASS” function can be selected to increase low frequency response output, or
decrease frequency response output. The “BASS” function will be working at only “OFF”
or “L.P.F” position.
e The BASS is adjustable from 0-12 dB boost at 50Hz.
Install the fuse holder that is less than 0.5 meters from the battery. Remember,the fuse is to protect
the safety of the car in case of a short. Connect fuse holder to battery,but do not install fuse at this
time.

MOUNTING:
1.After reading precaution, decide where you are going to install the unit. Also, see Fig.1.
2.Once the location has been determined, place the amplifier into position. Using a felt tip
pen of 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 this manner.
3.Remove amplifier. Drill four 3.5 m/m holes into mounting surface. If you want to mount
the amplifier to MDF or wood panel, drill four 3.0 m/m diameter holes into mounting surface.
4.\f possible, test the system to ensure it is operating correctly before final mounting of
the amplifier.
5.Mount the amplifier using the supplied 4 self tapping screws.
INPUT CONNECTIONS
This amplifier will accept low level inputs only. Low level is the same as line level. The low
level signal is carried through RCA cables. It is preferred to use low level inputs to the
amplifier if the head unit is equipped with the low level outputs. If not, you can use a “high
to low converter” available through your local car audio shop.
Connect the low level/line level RCA cable from the head unit, or signal processor, to the
line level input on the amplifier. See Fig.2 system wiring diagrams.
POWER CONNECTIONS
Itis important to have good quality power and ground connections, Remember, to complete
an electrical circuit, the ground connection is just as important as the positive power
connection. Before any power connections are made, disconnect the ground cable at the
battery.
When the power supply lead, memory backup lead of ground lead are extended use a 5mm’
(AWG5) or larger automotive grade cable which will withstand friction and heat to safe
grade against fires occurring as a result of short-circuiting.
GND=Connect the proper gauge ground wire to the amplifier “GND” terminal. Locate the
position on the chassis of the car to which the amplifier is to be grounded. The surface must
be free from any paint of dirt. This can be accomplished with a small grinding bit, sand
paper or wire wheel. NOTE: Do not ground the amplifier to the “frame of the car. The frame
on most cars and trucks is not grounded to the chassis (body).Use Solder or a clamp ring to
connect the ground wire. Pre-drill the prepped chassis to bolt the ground ring terminal with
nut, bolt and lick washers. Insulate metal and connector with paint or silicon to prevent
rust and oxidation. Silicon also works great to prevent nuts and bolts from working loose in
a harsh environment of an automobile. Upon completion of the ground connection, grab
wire or connector and confirm that it is a solid connection. To prevent engine noise, itis
recommended to ground the head unit and other audio electronics in the same location.
REM= Connect the remote wire (power antenna output) from the head unit to the remote
turn-on wire of the amplifier. If the head unit is not equipped with a remote/antenna output,
locate a wire of that is controlled by the accessory position of the key. It is important to have
the amplifier turn off the radio or key. If the amplifier remains on, the result will most
likely be a dead battery.
12V=Connect the proper gauge power wire to the amplifier “B+” terminal. Run wire to
2 CHANNEL AMPLIFIER BRIDGED WIRING
Tri-Mode Operational Output is a unique feature which allows a Crossover(Subwoofer)to be
operated in MONO mode,while the mainspeakers are playing in STEREO.
To engage the amplifier in this mode,place the CH1/2 and CH3/4 mode switches in the "FACT/
HIGH PASS’ position,and set the CH1/2 and CH3/4 higpass cross over to “FLAT, “Use a high pass
passive cross over network for eachof the mid/high speakers for Channels1-4,and a 15.9MH
low pass wire colfilter inductor to block high frequencies from eachof the subwoofers as
shown in the figure below.
