CONTROLS AND ADJUSTMENTS

A. CLIP LED Indicator for Output Clipping: Keep an  eye on the CLIP LED indicator located on the  remote Level knob. To prevent distortion and  ensure your audio remains clear and undistorted,  promptly turn down the Gain control.

B. GAIN: adjust the output level.

C. POWER: Green Light = Amplifier is ON.

D. VOLTMETER DISPLAY: shows the input voltage  of the amplifier in real time.

1. Remote Level Control Connection
   Connect the remote level control to this terminal. The  remote level control allows adjustment of the  subwoofer level from a remote location in the vehicle.

2. LPF/HPF Crossover
   Adjust the frequency setting of the low or high pass  crossover. for LPF, Frequencies higher than the  setting will be filtered out of the audio signal, for HPF,  Frequencies lower than the setting will be filtered out  of the audio signal.

3. LED Indicators:
   PWR: When the amplifier is on and in proper working  condition, the green LED will illuminate.
   CLIP: Clipping usually happens because the gain is set  too high in an attempt to maximize the amp’s output  potential. This can result in catastrophic damage to  your equipment, when the gain is set too high for the application the amp will produce a squared or clipped  sound wave, and the amp and the speakers connected  to it will generate a large amount of heat trying to  reproduce the clipped signal, this can result in  catastrophic damage to your equipment.
   PRT: If the amplifier activates its protection mode, the  red LED will illuminate. Refer to the troubleshooting  guide for possible solutions if the amplifier activates  its protection mode.

4. Level Sensitivity
   Adjust the amplifier’s pre-amp sensitivity level. The  minimum sensitivity level is 400mv, while the  maximum level is 3.6V.

5. RCA Audio Input Connection
   Using high-quality shielded stereo RCA cables,  connect the source signal to the amplifier RCA inputs.

6. Smart Cooling Fan
   Air recirculation system to help cool the amplifier  internally, the larger fan brings in cold air and the  smaller one draws hot air from inside.

7. Bass Boost
   Adjust the amplifier’s 50Hz Bass Boost level  up to 12dB.

8. Speaker Output Connector
   Connect the speakers to this output, the minimum  impedance is 1 ohm and it can be a speaker of any  range (subwoofer/woofer, mid-bass/mid-range, driver/tweeter). Make this connection carefully and  neatly.
   Strip your wire back and twist the exposed leads and insert them into the block terminal while being careful that there is no loose or frayed strands of wire and tighten down on the  terminal till the wire is tightly secured in place. If  the wires ever come in contact with each other the amplifier will go into protection. Know your total  ohm load before you make any connections.

9. Power Input Connector
   It is important to have good quality power and  ground connections. Remember, to complete an  electrical circuit, the ground connection is just as important as the positive power connection.  Before any power connections are made,  disconnect the ground cable of the battery. Use 4  gauge or larger automotive-grade wire if the  distance from the battery to the amp is excessive.  Avoid sharp or rough edges as a safeguard against  short- circuiting and potential fire hazards.
   GND = Connect the proper gauge ground wire to the  amplifier GND terminal. Locate the position on the  chassis of the car where the amplifier will be grounded. Use solder or a crimped ring terminal to  connect the ground wire. Pre-drill the prepped  chassis to bolt the ground ring terminal with a nut, bolt, and lock washer to insulate the metal. Coat  the connector with paint or silicone to prevent rust  and oxidation. Silicone also works great to prevent nuts and bolts from working loose in the harsh  environments of an automobile.
   Upon completion of the ground connection, grab  the wire end connector to confirm the connection  is solid. To prevent engine noise, it is recommended to ground the head unit and other  electronic audio devices in the same location.
   REM = Connect the remote wire (power antenna  output) from the head unit to the REM terminal. If  the head unit lacks a remote/antenna output, find a wire controlled by the accessory position of the key.  It’s crucial to ensure the amplifier turns off with the  radio or key. If the amplifier stays on, it may lead to  battery drainage.
   +12V = Connect the proper gauge power wire to the  B+ terminal. Trace the power wire through the car  to the in-line fuse or circuit breaker that is no more  than 18″ from the battery. Remember, the in-line  fuse or circuit breaker protects the car in the event  of a short circuit. Connect the in-line fuse or circuit  breaker to the battery, but do not install the fuse or activate the circuit breaker yet.

INSTALLATION

1. Before you start disconnect the negative  cable from the battery. Tape up the end so it is  isolated from the battery.

2. Run an appropiate gauge wire from the  battery to the amplifier. Plan this part of the  installation carefully. This cable will carry very  high current. If it should short to the body and it  is not properly fused it could catch fire.

3. ** Connect the power wire to the battery using a  fuse capable of handling the total current load of all  amplifiers connected. Do not install the fuse at this  point. Wait until indicated. Position the fuse as  close as possible to the battery. If the distance from  the battery exceeds 18 inches (wire length), it is  advisable to reassess both the wire and fuse  placement.**

4. Find the closest clear metal area to the amp  for a ground. Sand, grind or scrape all paint and  undercoating from the body and screw the  ground securely in place. It is advisable to test  the ground with an ohmmeter between the  ground cable and the negative battery cable to  ensure a good low resistance connection. Some  alloys used in some modern cars do not offer  the best ground.

5. Run the speaker wire to the speakers. it is  advised that you leave some extra wire at this  point! You can clean it up later.

6. If you haven’t already done so, mount the  amp now.

7. Connect the power and ground to the  amplifier (only after this step should you install the fuse to the positive battery terminal and the  negative battery terminal cable to its correct  terminal.)

8. Connect the remote wire from the head unit  to the amplifier. Now is a good time to turn on  the amplifier for the first time and make sure it turns on properly and does not go into  protection.

9. Connect the speaker wires to the amp and  speakers (make sure the amp is off first) make  sure the polarity (+ and -) are correct.
   

10. Connect the RCA’s to the amp.

11. Double check the amplifier’s control at this time.  Make sure everything is set correctly for your system.

12. Now you are ready to play it for the first time. It is  best to leave the gain all the way down at first. Start  with the head unit volume low and make your way up.

13. Now you can tune the amp. Take your time and  make only one adjustment at a time. It may take  some time to get the system fully adjusted. During  this time the amp is drawing current from the battery.  You should check the battery voltage from time to  time and recharge it if it gets low . That’s it . You are  done, have fun!
