Amplifiers provide high-performance sound reinforcement for your mobile audio
equipment. Its versatility enables compatibility with optional Equalizers, Frequency
Dividing Network Crossovers, and other audio processors in a customized system. The
Multi-Mode bridging capabilities allow flexibility in hosting several different speaker
configurations.
To achieve optimum performance, We suggest that your stereo components are
installed by an authorized dealer. It is highly recommended that you read this Owners
Manual before beginning installation.

PLANNING YOUR SYSTEM
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.
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 Low-Level (Pre-Amp outputs from
your radio)
signal source.
If your radio/source is equipped with Pre-Amp outputs. it is possible to utilize them
to drive the Amplifier and connecting (Amplifier) 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.
MOUNTING YOUR AMPLIFIER
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°C) in the
summer time. Since the thermal shut-down point for the Amplifier is 185°F(85°C), 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 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.
