INTRODUCTION
FEATURES - CLASS AB AMPLIFIER
High powered audio systems in a vehicle are capable of generating “Live Concert”
high levels of sound pressure. Continued exposure to excessively high volume sound
levels may cause hearing loss or damage. Also, operation of a motor vehicle while
listening to audio equipment at high volume levels may impair your ability to hear
external sounds such as; horns, warning signals, or emergency vehicles, thus
constituting to a potential traffic hazard.
WARNNIG
Before beginning the installation, consider the following:
a. If you plan to expand your system by adding other components sometime in the
future, ensure adequate space is left, and cooling requirements are met.
b.
Your Amplifier has been designed to accept either High-Level ( speaker outputs
from your radio ) or Low-Level ( Pre-Amp outputs from your radio ) signal source.
Should you use high or low level inputs?
If your radio/source is equipped with Pre-Amp outputs. it is possible to utilize them
to drive the Amplifier and connecting to the 2 rear speakers.
Then, use the built-in power of your radio to drive the 2 front speakers.
Distortion level is considerably lower from Pre-Amp (Low Level) outputs, than speaker(High Level) outputs.
c. Are your components matched? The peak 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)
d. Consider both the length of your leads, and routing when determining the
mounting location. Pre-Amp input Jacks require a length
(depending on location)
of high quality shielded male to male RCA patch cord.

PLANNING 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 designed with a thermal shut-down protection circuit,
making it reasonably tolerant of mounting variations. Any configuration which allows
moving air to be 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
cannot flow around fins.
Temperatures in car trunks have been measured as high as 175
F (80 ) in the
summer time. Since the thermal shut-down point for the Amplifier is 185
F (85 ), it is
easy to see that it must be mounted for maximum cooling capability. To achieve
maximum advantage of convection air flow in an enclosed trunk, mount the amplifier
in a vertical position, on vertical surface.

MOUNTING YOUR AMPLIFIER

MOUNTING SURFACE
Cooling requirements are considerably relaxed when mounting inside the passenger
compartment since the driver will not often allow temperatures to reach a critical
point. Floor mounting under the seat is usually satisfactory as long as there is at least 1
inch
(2cm)
above the Amplifier’s fins for ventilation.
a. Select a suitable location that is convenient for mounting, is 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 6 holes. USE EXTREME CAUTION, INSPECT UNDERNEATH SURFACE
BEFORE DRILLING.
c. Secure the Amplifier using the screws provided.
CONNECTING THE POWER

CAUTION
AS A PRECAUTION, IT IS ADVISABLE TO DISCONNECT THE VEHICLE’S BATTERY BEFORE MAKING CONNECTION TO
THE + 12 VOLT SUPPLY WIRING.
10 GAUGE
(Thicker if planning for additional Amplifiers)
wire is recommended for
both the power and ground wires. 20 Gauge, for the remote turn-on wire. Both
types available at most Mobile Audio Dealers or Installation Shops.
GROUND :
To Vehicle Chassis
To avoid unwanted ignition noise caused by ground loops, it is essential that the
Amplifier be grounded to a clean, bare, metal surface of the vehicle’s chassis.
NOTE
GROUND WIRE SHOULD NOT BE EXTENDED MORE THAN 3 FT. (1 METER).
USING THIS METFOD CAN CAUSE TURN ON AND TURN OFF TRANSIENTS (NOISE)
+12 Volt(Fused) Constant Power :
To Battery (+)
Due to the power requirements of the Amplifier, this connection should be made
directly to the positive (+) terminal of battery. For safety measures, install an in-line
50 Amp Fuse Holder (not included) as close to the battery positive (+) terminal as
possible .
With an ampere rating not to exceed total value of fuses in amp.
Remote Turn-On Input
:
To Power Antenna output of Car Stereo
This Amplifier is turned “ON” remotely when the vehicle’s stereo is turned “ON”.
NOTE
IF YOUR RADIO DOES NOT HAVE A +12 VOLT OUTPUT LEAD WHEN THE RADIO IS TURNED ON, “RMT” TERMINAL ON
THE AMPLIFIER CAN BE CONNECTED TO VEHICLE’S ACCESSORY CIRCUIT THAT IS LIVE WHEN THE KEY IS “ON”.
