Due to the power requirements of the amplifier, this connection should be made directly to the positive (+)
terminal of the battery. For a safety measure, install an in-line fuse holder (not included) as close to the battery
positive (+) as possible with an ampere rating not to exceed the total value of fuses in the amp.

Planning and Mounting Your System [lll tll LL LLLLLLEL
E EEES
Planning Your System
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.
NOTE:
DISTORTION LEVEL IS CONSIDERABLY LOWER FROM PRE-AMP (LOW LEVEL)
OUTPUTS, THAN SPEAKER (HIGH LEVEL) OUTPUTS.
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 1-8 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.
Mounting Your System
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.
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.
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.

Adjusting and Tuning
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.
ADJUSTING THE AUDIO LEVEL
For the best performance, you must set GAIN (4V/0.2V) on the side of the amplifier to
adjust the level of the audio signals that enter the amplifier.
. Use a screwdriver to turn GAIN (4V/0.2V) fully counterclockwise to 4V.
. Turn the auto sound system's volume control to about one-third of its full range.
. Adjust GAIN (4V/0.2V) to a comfortable listening level.
. 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 (4V/ 0.2V) 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.

Warning / Disclaimer
WARNING
Investigate the layout of your automobile thoroughly before drilling or cutting any holes.
Take care when you work near the gas tanks, 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
equipment 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 different type or rating may result in damage to
this system which is not covered by the warranty.
