• If afterreading the directionsyou feel uncomfortableabout installing theamplifier in your
car, or not equipped or competent to do so, you should have the amplifier installed by an
• Negative battery terminal must be disconnected before any electrical connections are made.
• Be surechoose a locationthat provides substantialventilation for theamplifier. 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 alongthe length ofits heatsink finsfor cooling.
• NEVERmount the amplifier upside down,this willcause theheat to rise backinto the
amplifier causing thermalshutdown or possiblepermanent damage.
• NEVER mount the amplifier in a location that is subject to direct sunlight or exposed to
moisture.
• Be sureto mount the amplifier to astrong, solid surface which will notgive way underthe
stress of asudden stop oraccident.
• Make sure that the mounting screws will not penetrate the gas tank, brake and fuel lines,
wiring or othercritical parts ofyour car wheninstalled.

• 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
• 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.
• To help minimize interference, it is best to run the power cables along the opposite side
.
• Whenever wires pass through metal, rubber or plastic grommets must be used to prevent
• 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
• 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
• 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

INPUT CONNECTIONS
It is 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

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 or 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 lock 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, it is

This amplifier will accept low level inputs only. Low level is the same as line level. The low

This amplifier can operate in one, two or three channel mode. The minimum impedance for
single channel (bridged/mono) operation is 4 or 8 ohms. Tri channel power is referred to
stereo and mono at the same time. Minimum impedance remains the same for three channel
(front /subwoofer) systems as long as proper passive crossovers are used. Connect right
and left speaker wire to corresponding speaker output terminals of the amplifier. Be sure to
have the positive wire from the speaker connected to the positive speaker terminal of the
amplifier and the negative wire from the speaker must connect with the negative speaker
terminal of the amplifier. Reversing any of these connections will result in the speaker cones
moving out of phase which causes bass cancellation. See Fig.3 Speaker Output Connections.

ADJUSTMENTS
1.Set to 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
2.Set to the "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
3.Set to 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
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 head unit or other signal processor. Start 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 millivolts) 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 a minimum. It is important not over drive speakers (at point of distortion)
this will cause permanent damage to the speakers. Also, if the amplifier itself is over driven,
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"
