This control adjusts the amplifier's sensitivity. Input sensitivity is variable from 200 Millivolts to 4 volts. Clockwise
increases sensitivity. Counterclockwise decreases sensitivity. THE KNOB IS NOT A VOLUME CONTROL. A
lower signal level will require increased sensitivity for full power. A higher signal will require decreased sensitivity.

-PWR (Power) : This BLUE LED will illuminate when the amplifier is turned "ON". If it fails to illuminate, check the power
connections to the amplifier and fuses.
- PROT (Protection) : The amplifier protection circuitry will disable the amplifier if input overload, short circuit, or extremely
high temperature conditions are detected. When the protection mode is in operation, the LED indicator on the side
panel will be illuminated red, indicating the amplifier has gone into a self-preservation mode.
If you observe that the protection LED is lit, please check the system carefully to determine what has caused the
protection circuit to engage. The amplifier shut down due to a thermal overload condition, please allow it to cool
down before restarting. If the amplifier shut down because of an input overload or short circuit, be sure to repair these
conditions before attempting to power up the amplifier again.

b. Are your components matched? The RMS power rating of your speakers must be
equal or greater than the amplifier's. They also must be 2-8 Ohms impedance
(this information is normally printed on the speaker magnet).
c. Consider both the length of your leads, and routing when determining the mounting
location. Pre-Amp input Jacks require a length of high quality shielded male to male
RCA patch cord.
NOTE:
DISTORTION LEVEL IS CONSIDERABLY LOWER FROM PRE-AMP (LOW LEVEL)
OUTPUTS, THAN SPEAKER
(HIGH LEVEL) OUTPUTS.
Before beginning the installation, consider the following:
a. If you plan to expand your system by adding other components sometime in the
future, ensure that adequate space is left, and cooling requirements are met.
If your radio/source is equipped with Pre-Amp outputs, it is possible to utilize them
to drive an Amplifier and connecting (amplifier) to the 2 rear speakers.
Then, use the built-in power of your radio to drive the 2 front speakers.
a. Select a suitable location that is convenient for mounting, accessible for wiring, and
has ample room for air circulation and cooling.
b. Use the amplifier as a template to mark the mounting holes. Remove the amplifier
and drill holes. Use extreme caution. Inspect underneath the surfaces before drilling!
c. Secure the amplifier using the screws provided.
The mounting position of your amplifier will have a great effect on its ability to dissipate
the heat generated during normal operation. It has an ample heat sink for heat
dissipation, and also is designed with a thermal shut-down (for heat protection) circuit,
having enough air directed over the cooling fins will improve heat dissipation dramatically.
DO NOT enclose the amplifier in a small box or cover it so that air can not flow around
the fins. Temperatures in car trunks have been measured as high as (155 F) in the
summer time. Since the thermal shut-down point for the amplifier is (158 F) it is easy
to see that it must be mounted for maximum cooling capability. To achieve the maximum
advantage of convection air flow in an enclosed trunk, mount the amplifier in a horizontal
position. Cooling requirements are considerably relaxed when mounting inside the
passenger compartment since the driver will not allow temperatures to reach a critical
point. Floor mounting under the seat is usually satisfactory as long as there is at least 1
inch (2.54 cm) above the amplifier's fins for ventilation.
CAUTION: Before connecting any wires to the amplifier, disconnect the ground lead from
the battery. Leave the ground lead disconnected until you are done wiring the
amplifier.

TURNING ON THE AMPLIFIER
The amplifier automatically turns on a few seconds after you turn your vehicle's ignition
switch to ACC or turn on your auto sound system (depending on how you have wired
the system). The POWER indicator on the top of the amplifier illuminates when the
amplifier is on.
Important: Your amplifier requires 30 amps or more of power from your vehicle's
battery during operation. To protect your battery from discharging, do not operate the
amplifier unless your vehicle is running.
Note: Your amplifier temporarily shuts down if it gets too hot, then restarts automatically
once it cools.
NOTE Raising the LPF frequency allows higher frequencies to reach the bass speakers
while blocking lower frequencies from midrange speakers. Lowering the LPF frequency
allows lower frequencies to reach the midrange speakers while blocking higher
frequencies from bass speakers.

Adjusting and Tuning
For the best performance, you must set GAIN (MIN/MAX) on the side of the amplifier to
adjust the level of the audio signals that enter the amplifier.
1. Use a screwdriver to turn GAIN (MIN/MAX) fully counterclockwise to MIN.
2. Turn the auto sound system's volume control to about one-third of its full range.
3. Adjust GAIN (MIN/MAX) to a comfortable listening level.
4. Turn up the auto sound system's volume control until the sound begins to distort.
Then immediately turn the volume down to a point just before where the distortion
began.
Caution Never turn up the auto sound system's volume control more than needed
to adjust the audio level (More than two thirds of its maximum volume).
5. Adjust GAIN (MIN/MAX) until the sound is at the maximum level you want the amplifier
to produce.
6. Adjust the auto sound system's volume control to a comfortable listening level.

Investigate the layout of your automobile thoroughly before drilling or cutting any holes.
Take care when you work near gas tanks, gas lines, hydraulic lines, and electrical wiring.
Do not use the power amplifier unmounted. Attach the system securely to the automobile
to prevent damage, particularly in the event of an accident. Do not mount the system
so that the wire connections are unprotected or are subject to pinching or damage
from nearby objects.
The +12V DC power wire must be fused at the battery positive terminal connection.
Before making or breaking power connections at the system power terminals,
disconnect the +12V wire at the battery end. Confirm your radio/head unit and/or other
equiptment is turned off while connecting the input jacks and speaker terminals.
If you need to replace the power fuse, replace it only with a fuse identical to that
supplied with the system. Using a fuse of a different type or rating may result in damage to
this system which is not covered by the warranty.
