low pass portions of the crossover can be set independently of one another.
In most car audio installations, there is a tendency for a boom.”
Because of their interior dimensions, most cars will resonate or ring at these
frequencies. If we design the system so there is less musical
information in this region, the final response is very smooth and natural
sounding. The high pass filter is variable from 60 to 240 Hz at 12

For initial setup, setting the low pass filter to approximately 60 Hz,
