INSTALLATION

1.Most speaker systems require rather heavy boost at the lowest frequencies due to the large amount of air that must be moved. However, speaker woofer cones resontate between 4560Hz where output is higher so do not boost too much at 60Hz. Use heavy boost at 150Hz, Less boost at 400Hz.

2.Due to sound-wave reflections between the front and rear windshields of a typical vehicle, there may be heavy loss between 700Hz to 1.3kHz so moderate boost here is very effective and will create more "presence" for vocalists.

3.The mid-rangefrom 3 to 6kHz should not require much change from flat (center) Most speakers work well here. Adjust per your taste.

4.Due to limitations in human hearing. sound above 8kHz is not heard very well. Moderate boost at 1kHz adds a crisp charactr when percussion instruments are present.
