INTRODUCTION
This power amplier has been designed to provide high quality performance
with a minimum of maintenance. However, it's performance will only be as good
as the care and quality of components with which is installed.
We therefore advise that you read these instructions very carefully to familiarize
yourself with the product and it's features.
Before installing the power amplier please read this instruction manual
carefully. The instructions for mounting and connecting the set have to be
followed precisely. If necessary, a service center should be consulted.
All connections for DC power, signal input and speaker outputs can be carried
out easily and safely byway of RCA and screwed terminals.
INSTALLATION INSTRUCTIONS
Please choose a mounting place without any direct weather inuences.
Note that the amplier generates heat so that a well ventilated place is necessary.
According to your car's construction the set can be made very carefully in order
to ensure the amplier's full performance and reliability.
Keep the wire connections as short as possible with sucient dimensions in
order to minimize power losses and provide a higher audio output of the system.
For safety reasons route all power and speaker wiring by using the exiting wire
channels. To minimize damage to the cables, take care that they do not pass
sharp edged metal. Lay all cables as far away as possible from the ignition cables,
modules in the boot and under the key dashboard, as this create interference.
Add a fuse into the (+) power cable in a distance of not more than 30 cm from
the positive battery pole.
Keep the length of the power wires as short as possible. It is better to use power
cables which are short and then longer speaker cables.
In order to reduce interference, also pay attention to the instructions.

PRECAUTIONS
• This unit is designed for negative ground 12-14.50 VoIts (DC) operation only
• Use speakers with an impedance of 2 or 4 Ohms (4 to 8 Ohm when used as
bridged amplier)
• Avoid installing the unit where:
•It would be subject to high temperatures, such as from direct sunlight or hot
air from the heater.
•It would be exposed to rain or moisture.
•It would be subject to dust or dirt.
• If your car is parked in direct sunlight and there is a considerable rise in
temperature inside the car, allow the unit to cool o before operation.
• When installing the unit horizontally, be sure not to cover the heatsink ns
with the oor carpet.
• If this unit is placed too close to the car radio, an interference may occur in this
case, separate the amplier from the car radio.
• This power amplier employs a protection circuit to protect the transistors and
speakers if the amplier malfunctions.
• Do not attempt to test the protection circuits by covering the heatsink or
connecting improper loads.
• Do not use the unit with a weak auto battery as its optimum performance
depends on a normal battery supply voltage.
• For safety reasons, keep the volume of your car audio system moderate so that
you can still hear normal trac sounds outside your car.
FUSE REPLACEMENT
If the fuse blows, check the power connection and replace the fuse. If the fuse
blows again after replacement, there may be an internal malfunction.
In this case, consult your dealer.
WARNING: Use the specied amperage fuse. Use of a higher amperage fuse
may cause serious damage.
PROTECTION CIRCUIT
This amplier is provided with a protection circuit which operates in the
following cases when:
• the unit is overheated.
• the speaker terminals are short circuited.

WIRING INSTRUCTIONS
POWER CONNECTION
The battery terminal (BATT) must be connected directly to the positive terminal
of the vehicle battery to provide an adequate voltage source and minimize noise.
Connecting the battery terminal lead to any other point (such as the fuse block)
will reduce the power output and may cause noise and distortion.
Use only #10 gauge or thicker (smaller gauge #) wire for this lead and connect
it to the terminal of the battery after all other wiring is completed.
GROUND CONNECTION
The ground terminal (GND) connection is also critical to the correct operation
of the amplier. Use a wire of the same gauge as the power connection (#10 or
thicker) and connect it between the ground terminal (GND) of the amplier and
a metal part of the vehicle close to the mounting location. This wire should be as
short as possible and any paint or rust at the grounding point should be scraped
away to provide a clean metal surface to which the end of the ground wire can
be screwed or bolted.
REMOTE TURN-ON CONNECTION
The amplier is turned on by applying + 12V to the remote turn-on terminal
(REM). The wire lead to this terminal should be connected to the "Auto-Antenna"
lead from the car stereo which will provide the + 12V only when the car stereo
is turned on. If the car stereo does not provide an "Auto-Antenna" lead, the
remote turn-on lead may be wired to an "Accessory" or "Radio" terminal in the
car's fuse block. This will turn the amplier on and o with the ignition key,
regardless of whether the car stereo is on or o. The remote turn-on lead does
not carry large currents. So # 20 gauge wire may be used for this application.
SPEAKER CONNECTIONS
Depending on the type and number of speakers used with the amplier wire
them to the speaker terminals as per the appropriate wiring diagram. For most
applications # 18 gauge wire should be used for the speaker leads but in no case
thinner than # 18 gauge. For leads is excess of 10 feet # 12 gauge is recommended.
When wiring the speakers, pay careful attention to the polarity of the terminals
on the speakers and make certain they correspond to the polarity of the
corresponding terminals on the amplier. Do not ground any speaker leads to
the chassis of the vehicle.

BRIDGED MODE
POWER CONNECTION LEADS
NOTES ON THE POWER SUPPLY
• Connect the + 12V power input lead only after all other leads have been
connected.
• Be sure to connect the ground wire of the unit securely to a metal part of the car.
• A lose connection may cause amalfunction of the amplier.
www.PyleUSA.com 7
• REM: The unit is turned on by applying + 12 Volts to this terminal. This terminal
does not draw heavy current like the tow Power Terminals so a thinner
connecting wire is acceptable. Standard 20 GAUGE is ne and the standard
color is blue. If the radio is equipped with a Power Antenna control wire, it can
drive this terminal. If the Power Antenna wire is already in use, you can still
splice into it. With this method, the unit will turn on automatically with the
radio.
• Use the power supply lead with a fuse attached whose value is the same as
original fuse.
• Place the fuse in the power supply lead as close as possible to the car battery.
• During a full power operation, maximum current will run through the system.
Therefore, make sure that the leads to be connected to the + 12V and GND
terminals of the unit respectively must be larger than 10 - Gauge (AWG. 10).
OPERATION
After the amplier has been installed and all connections have been made
carefully and securely, turn the radio so that the amplier is switched on ON
automatically. After a short power-on period, the amplier reaches its full
performance. Now turn up the volume slowly using the volume control of the
radio. If there is no sound or only a distorted replay, switch o the radio
immediately - the amplier will also switch o automatically - and check if all
connections have been made correctly.
GAIN = INPUT LEVEL CONTROL
The input level control allows the system to work well within a wide range of
output level. Choose the adjustment in the way that you achieve a sound
most possibly without any distortion.
As a guideline the following procedure is recommended:
• If you use several ampliers, the adjustment has to be made for each set
separately. Tune in the volume of your car radio to2/3 of the maximum volume.
Now turn the gain control of the amplier from “Min“ to “Max“ direction until
you can hear distortions. Then turn the level control a little back to "Min".
The gain control adjustment is nished now.
• Attention! If you use 2 Ohm speakers in stereo mode. Tri-mode or 4 Ohm
speakers in bridge mode and the overload protection is triggered out, turn the
gain control to "Min" direction, until the operation is free of trouble.

X-OVER FREQUENCY CONTROL
A. When the crossover control is in the Low-Pass position, this control becomes
active allowing you to select your crossover point.
B. When the crossover control is in the High-Pass position, this control becomes
active allowing you to select your crossover point.
CROSS OVER SWITCH
• Full: full range frequency.
• Low pass: the lower frequency under setting point can be pass.
• High pass: the higher frequency above setting point can be pass.
BASS BOOST CONTROLS
This amplier has Bass controls for making good sound combination.
FUSE
The amplier is equipped with a plug-in auto fuse protecting the set against
fault conditions. Do not use a fuse with a higher value and never bridge the fuse
over, as this may lead to irreparability damage so that any claim for warranty is
denied.
GND (-) = GROUND CONNECTION
Connect the GND terminal to the chassis ground of your car and take care of
best electric and mechanic contact. ln doing so, drill a hole in to the car chassis
near the amplier then remove color, dirt, or any other substance from the
ground point. Thereafter fasten the cable end with added ring terminal by
using a screw. Ensure that the ground connection is as short as possible and
that the cable diameter is sucient (min 4mm”). Route the ground cables from
the radio and all other equipment parts, like equalizer, active crossover network
or other ampliers, to the same ground point.
+ 12V = POWER SUPPLY
Connect the BATT terminal to the positive pole of the battery with a lead cable
and add a fuse into the power cable in a distance of not more than 30 cm from
the battery. The lead cable's diameter should be at least 4 mm’ for a length of
3 m and 6mm" for a length of 6m.
www.PyleUSA.com 9
REM (ON/OFF) REMOTE CONTROL
Connect the REM terminal to the automatic antenna connector of your car radio.
Now when turning and your car radio, the amplier automatically ON OFF
switches and ON OFF. A cable diameter of 0.5 mm’ is sucient.
TROUBLESHOOTING
No Function
The connection cable is not connected correctly (=terminaI + I2V/GND/REM).
Ensure that all connections and mechanic contact and that the jacket has been
removed. The fuse is defective-pay attention to the correct value of a new fuse!
No Sound
Speaker cable or speaker plug are not connected correctly.
No Sound/Red LED Protection is lit
The plus and minus wires of the speaker cable have contact, thus eliminate the
short circuit. If you use a 2 Ohm speaker in stereo mode, a 4 Ohm speaker in
bridge mode or tri-mode and the set is overloaded, then turn the gain control to
"min" until the operation is free of trouble.
Poor Sound Quality (Distortions)
The speakers are overloaded, therefore turn down the volume level and check
the volume control positions.
No Stereo Sound and Weak Bass
Speaker cables (+) and (-) are mixed up, unit wired out of phase.

INTERFERENCE
All cables can source and create interference. The power cable and Cinch/RCA
audio cable are very prone to interference; the remote cables are less prone.
There is often interference caused by the generator (piping), ignition (cracking)
or other car electronic parts. Most of these problems can be eliminated by
correct and careful cabling. In doing so, here are the following guidelines:
• Use only a screened audio cable for the wiring between "low level in" of the
amplier and RCA or DIN output of the radio.
• Lay the signal, speaker and power cables separately with enough distance from
one another and also from each others car cable. If not possible, you can lay
the circuit and ground cable together with the serial cables. Audio and speaker
cable should be as far away from these as possible.
The REM cable to the automatic antenna output of the radio can be laid
together with the signal cables.
• Avoid ground loops by laying the ground wiring of all components to a center
point in a star-like way. You can nd the best central point in measuring the
voltage directly at the battery. Now compare this voltage value with the chosen
ground point and the (+) terminal of the amplier. If measured voltage is only
slightly dierent, you've found the correct central. Otherwise you have to look
for another point. You should measure with the ignition point for earth being
switched on and additionally switched on consumers (rear window heating
and light).
• If there are pickups from external electrical sources into the speaker cables,
divide the core leads and twist them together.
• If there are noises from the car electrics, add an interference suppression choke
into the power wiring.
• If there are humming noises, use thicker ground cables or add further ground
cables to the chassis.
• To reduce contact resistance and bad loose contact, please solder the cable
ends or use multi core cable ends, spade terminals or others. Gold Plated
spade terminal are free of corrosion and have the lowest contact resistance.
• Should all these meaures be without any success, the use of a ground loop
isolator may solve the problem.
