This product cannot be used in cars fitted with a common negative speaker system.
To prevent external noise from entering the audio system:
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. 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.
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.
