I have a Kenwood 225MR for my boat and it does not have high pass crossover/filter.
the deck powers 4 co-axial speakers and im woundering if this is correct
with the bass at -8 it doesnt remove the lows enough so say:
saying at 80 hertz with a 6db slope would that almost filter out the lows or would a 12db work better?
am i correct?
