3. Connect the line input to the amplifier using the Level, HP Filter, LP Filter, and X-Over connections.
4. Adjust the settings of the high pass and low pass filters according to your preference using the HP and LP buttons.
5. Adjust the crossover settings using the X-Over button.
6. Adjust the protect power feature using the Protect Power button.
7. Adjust the level of the sound using the Level button.
8. Turn on/off the high pass filter using the HP button.
9. Turn on/off the low pass filter using the LP button.
10. Use the MIN and MAX buttons to adjust the minimum and maximum levels of Ch1/Ch2 and Ch3/Ch4.

INSTALLATION SPECIFICATION

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!

INSTALLATION

• 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 ch armay from the receiver. Good locations include under a seat, in the trunk or hat

• 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 or a surface preventing air circulation. of the heat sink are not against a panel

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 vehicle’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 100dB may cause permanent hearing loss. High power autosound system may produce sound pressure levels well over 130dB, use common sense and practice safe sound please !

POWER CONNECTION

IMPORTANT! Before making any connections, disconnect the car’ s battery until the installation is completed to avoid possible damage to the electrical system

• The +12V DC power cable should be heavy gauge stranded copper cable with heavy insulation, since it draws power directly from the positive battery terminal.
  Select the cable gauge at least 10mm2. And the ground cable gauge should be the same as the +12V DC.

• 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.

• Connect the GROUND Power terminal directly to the battery (-) position terminal or the car chassis. Ensure that all paint or other insulation is remove from around the hole area, and using self tapping screw, securely affix the bare wire ends to the vehicle chassis. Use as short as possible.

• 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 ON/ 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.

CHANNEL AMPLIFIER-APPLICATIONS

• INPUT CONNECTIONS

  • This amplifier has RCA connections for low level inputs. Low level signal is carried through RCA cables. it is preferred to use low level inputs to the amplifier if the head unit is equipped with the low level outputs.

• SPEAKER OUTPUT CONNECTIONS
  You do not need to make any adjustment for the input connection of amplifier before you connect the speaker output.

• SPEAKER OUTPUT CONNECTIONS

  • You do not need to make any adjustment for the input connection of amplifier before you connect the speaker output.
  • Connect right and left speaker wire to corresponding speaker output terminals of the amplifier.
  • Be sure to have the positive wire from the speaker to the positive speaker terminal of the amplifier and the negative wire from the speaker must connect with the speaker terminal of the amplifier. Reversing any of these connections will result in the speaker cones moving out of phase which causes bass cancellation.

• LEVEL CONTROLS
  Turn the VOLUME control on the amplifier Once the initial power sequence has been control to roughly 80% of full. Insert a CD up the amplifier VOLUME control until you for clean sound. to Min initially. performed, set the CD/ RADIO volume or tune to a radio station and slowly turn hear some distortion, and then back it off for clean sound.
