Here
we
present a variation
of
the
previous system. Since
this
is
a 2
way
system,
wecan
use
the
front
outputs
from
a head
unit
to
drive
the
highs,
and
the
rear
output
to
drive
the
bass
This
method
allows
the
listener
to
easily adjust
the
relative levels
of
bass
to
highs,
with
the
front
to
rear
fade
on
the
head unit. Channels 1
anf
2
will
be
used
for
highs,
and
channels 3
and
4
for
mono
bass.
