CONNECTION

• This product cannot be used in cars fitted with a common negative speaker system.
• To prevent external noise from entering the audio system:
  • Locate the unit and route the leads at least 10 cm away from the car harness.
  • Keep the power lines as far away from other leads as possible.
  • Connect the ground lead securely and safely to a bare metal spot (remove the coating if necessary) of the car chassis.
  • If you add an optional noise suppressor, connect it as far away from the unit as possible. Your Alpine Dealer can provide various noise suppressor solutions, contact them for further information.

• Your Alpine Dealer knows best about noise prevention measures so consult your dealer for further information.
• Ensure secure connections.
• Any unused connections should be insulated with electrical insulation tape.
• If the on-board computer or similar device, such as the ECU, contains security code, you may loose the memory when connecting the negative lead.

1. Disconnect the cable from the negative terminal of the car battery.
2. Connect
   • CONNECTIONS FOR RCA INPUT
     
     (Connect the ground lead securely and safely to a bare metal point on the vehicle chassis.
     • Always use the extension cable supplied for connecting the +VE battery terminal.
     • DO NOT connect this lead to the head unit.
     • DO NOT modify this cable. It may cause malfunction and damage to the product)

• CONNECTIONS FOR SPEAKER LEVEL INPUT
  
  (If your head unit does not have this lead, then please connect to the the ACC lead of the vehicle. The lead that supplies power when the key is at the ACC position.
  Please connect to either the rear or front speaker output leads.
  
  The output of the subwoofer will be affected by the head unit fader settings.
  Connect the ground lead securely and safely to a bare metal point on the vehicle chassis.
  • Always use the extension cable supplied for connecting the +VE battery terminal.
  • DO NOT connect this lead to the head unit.
  • DO NOT modify this cable. It may cause malfunction and damage to the product)

	Failure to do so may result in fire, accident or electrical shock.
	Bolts or nuts used for the brake or steering systems (or any other safety related system), or tanks should NEVER be used for installations or ground connections. Using such parts could disable control of the vehicle and cause fire, etc.

ADJUSTMENT

If there is distortion or you hear a popping sound from the subwoofer, the input level is too high. If the subwoofer has prolonged use in this condition, this may result in deterioration of performance or may cause damage to the subwoofer.

1. POWER INDICATOR
2. INPUT GAIN ADJUSTMENT
3. LOW PASS FILTER ADJUSTMENT
4. PHASE SELECTOR

1. Set the gain to MIN, Phase to NORM.LPF to CENTER before swithing on the system.
2. Set the Bass/Treble adjustment to zero on the head unit. Set the volume to your average listening level. lt may help to use a music source that is familiar.
3. Next, gradually increase the gain level and system volume to a point where system balance is achieved. If the gain level is set too high, the subwoofer may begin to distort. Distortion may also occur if the volume is set too high on the head unit. Check that the other speakers have not begun to distort before proceeding with the adjustment. If the entire speaker system in the car is distorting, reduce the volume of the head unit.
4. Once the gain has been set, adjust the L.P.F (Low Pass Filter) at afrequency which compliments your speaker system. (We recommend using CENTER as a starting point.)
5. Adjusting the L.P.F will change the output volume of the subwoofer. Repeat procedures 3 and 4 until the ideal setting is found.
6. The final adjustment is the PHASE of the subwoofer. While sitting in the driver's seat and with music playing, switch to a better setting between NORM and REV - The ideal PHASE setting varies from car to car, depending on the location of the subwoofer and the interior acoustic characteristics of the car.
