Connections
in
series
Using multiples
of
subwoofers for such comprehensive installations, it
is
sometimes better to
connect
them
together
in
a series circuit. Using a low impedance load
to
the amplifier effectively ensures it will
work
less
hard.
For connecting the subwoofers, they are effectively
looped
together
in
any series circuit.
Thus the positive
(+)
of
1
st
subwoofer will be connected to the positive (+)
of
the amplifier.
The negative
(-)
of
the 1
st
subwoofer will be connected
to
the positive (+)
of
the 2nd subwoofer.
Then
depending
on
how
many subwoofers are to be included this
looping
will continue, until the last
(in
this
basic case the
2nd
subwoofer), will have
its
negative
(-)
connected to the negative
(-)
of
the amplifier.
Calculation
of
the impedance
is
(Z),
for
the given impedance value
nominal
(R),
is
4 ohms.
• 2 subwoofers : Z = R1 +
R2
Z = 4 Q + 4 Q Z = 8

Connections series and parallel, combined
Depending on
your
installation amplifier(s), subwoofer(s), various combinations
of
series and parallel circuits
can be used. The real advantage
of
doing
this
is
to have a
system
with available power, but at the same time
to ensure the system impedance load
is
optimum
for
the amplifier(s) used.
