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 4 kHz with x20-
switch in x20 position
Rear: HP-filter 80 Hz or fullrange
LP-filter IN, setting 4 kHz with
x10 switch in position x1
Sub: LP-filter 60-80 Hz
Use one, two or three RCA-cables
for signal from head unit to amplifier.
