Precautions: Read First!  
• 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  
authorized installer. It's your car!  
• 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 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.  
NEVER mount the amplifier up side down, this will cause the heat to rise back into 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 theamplifier to astrong, solid surfacewhich will notgive way underthe  
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 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  
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 metal 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 totest the system before theamplifier 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 SOUNDPRESSURE LEVELS OVER 100dB MAY  
CAUSE PERMANENT HEARING LOSS. HIGH POWEREDAUTOSOUND SYSTEM  
MAY PRODUCESOUND PRESSURE LEVELS WELLOVER 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 Fig.1.  
2. Once thelocation has beendetermined, place theamplifier into position. Using a felttip  
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 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 3.0m/m diameter holes into mounting surface.  
4. If 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.

CONNECTIONS  
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 throughyour local caraudio shop.  
Connect the low level/line level RCA cables from the head unit, or signal processor, to the  
line level inputon the amplifier. See Fig.2system wiring diagrams.  
POWER 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  
battery.  
When the power supply lead, memory backup lead or ground lead are extended use a 5mm²  
(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 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  
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 that is controlled by the accessory position of the key. It is important to have  
the amplifier turn off with 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  
wards the fuse holder that is no greater then 0.5 meters from the battery. Remember, the  
fuse is to protect the safety of the car in the case of a short. Connect fuse holder to battery,  
but do not install fuse at this time.

SPEAKER CONNECTIONS  
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 whichcauses bass cancellation. See Fig.3Speaker 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  
between 80Hz to 1.2kHz & 50Hz to 500Hz as the crossover point.  
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  
& 50HZ to 500Hz as the crossover point.  
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  
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 200 millivolts to 6  
volt from the head unit or other signal processor. Start by setting the sensitivity adjustment  
to the "MIN" (6 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 damageto the speakers. 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.  
• The BASS is adjustable from 0 ~ 12dBboost at 50Hz.
