Congratulations on purchasing the High Speed Power Amplifier. The amplifier
has been designed using the latest electronic technology available, allowing
you to produce high quality stereo reproduction in mobile applications. This
system provides you with low harmonic distortion, a huge considerable amount
of reserve voltage and high temperature stability.
Just enjoy the perfect sound this amplifier takes to you!

*
Since the amplifier is sensitive to electrical and motor noise and interference from
the amplifier may affect your radio reception, try to mount it at least 3 feet away from
the receiver. Good locations include under a seat, in the trunk or hatch area.
* Please remember this
is a high power unit which generates high electrical energy
and heat. Therefore be sure to install the unit in a place with sufficient airflow, a
minimum of dust and no moisture. Allow enough space around the cooling fins to
permit reasonable airflow and cooling. It is important to ensure that the cooling fins
of the heat sink are not against a panel or a surface preventing air circulation.
*
Never mount the amplifier in a location that is subject to direct sunlight or exposed
to moisture. Be sure to mount the amplifier to a strong, solid surface which will not
give way under the stress of a sudden stop or accident.
* When
mounting the amplifier on a side wall, try to position it so that the slots in
the cooling fins are vertical. Amplifier should not be mounted on the bottom of a rear
deck with the fins facing down because the heat will radiate back up into the
amplifier. Leave yourself enough room on either side of the amplifier to make all the
wire connections and adjust the controls. If you have a subwoofer box in your vehicle,
you can mount the amplifier on the outside of the box.
Caution: If you are mounting the amplifier to the rehicle's floor, check beneath the car
to be sure your screws won't puncture a brake or gas line.
WARNING!
Continuous exposure to sound pressure levels over lOOdB
may cause permanent hearing loss. High power auto sound
system may produce sound pressure levels well over
130dB, use common sense and practice safe sound please!

*
Connect the +12V Power terminal to the battery(+) position terminal. An in-line
fuse must be installed in the +12V power cable near the battery less than 50mm.
Without one, an accidental short circuit could pose a fire hazard and damage your
amplifier. Connect the fuse holder to battery, however, do not install fuse at this time.

Many radio's and other music sources have an output terminal for connection of
the remote turn on of the power amplifier. CONNECT the output terminal to the
amplifier REM control jack. If a radio doesn't have a remote turn on feature,
you can connect the REM pole to external switch for positive + 12V ONI OFF.
* To
help minimize interference, it is best to run the power cables along the opposite
side from the audio cables.
Caution: The power cables must be connected tightly. A loose
connection may cause malfunctions or interference noise or
distortion.
