1. Set the GAIN to MIN, PHASE to NORM, LP FILTER to CENTER before switching on the system.
2. Set the Bass/Treble adjustment to zero on the head unit. Set the volume to your average listening level. It
may help to use a music source that is familiar.
3. Next, gradually increase the gain level. Increase the level to the point where the sound of your system, as
a whole, is balanced. 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 LP FILTER at a frequency which compliments your speaker
system.
5. Adjusting the LP FILTER 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 between NORM and REV. Select the setting which sounds better –The ideal PHASE
setting varies from car to car, depending on the location of the subwoofer and the acoustic characteristics
of the vehicle interior.
