If you have problems with the mid
bass driver "reaching the bottom"
(the voice coil touches the bottom
pole plate) at high volumes, use
the HP-filter to avoid this with a
setting at 50 - 80 Hz or higher.
Make your own tests.
Filter settings:
Front: HP-filter 80 Hz or fullrange
Rear: HP-filter 125 Hz
LP-filter IN. Setting 6 kHz with
x10 switch in position x10
Sub: LP-filter 70-80 Hz
Use one, two or three RCA-cables for
signal from head unit to amplifier.
