our
4 ohm Dual
Voice
Coil
Speaker for
2
channel
connection:
Note, the
following
speaker models
from Retrosound (R-57N, R-410N, R-69N , R-65N)
feature Dual
Voice
Coils,
this
allows
you to connect
left
and right speaker
channels to one
speaker, this
will
give you a
fuller,
richer sound for
vehicles
that
only
have one
single
speaker mounted in the dash
or
the rear deck area.

Wiring our 4 ohm Dual
Voice
Coil
Speaker in series so the
amplifier
sees an 8 ohm
impedance:

models
from Retrosound (R-57N, R-410N, R-69N,R-65N)
feature
Dual
Voice
Coils,
Wiring
the voice
coils
in
series allows the unit's
amplifier
to see
an 8 ohm
nominal load.
This is an advanced wiring concept and
should only
be done
by
experienced and
knowledgeable installers.
For other configurations or
general questions,
please email

A
note
about
nominal
impedance:
Nominal Impedance
is
the
manufacturer's
specification
given
for
the
speaker.
It
is
meant
to
represent
the
average
impedance
a
speaker
presents
to
an amp. Resistance
fluctuates
constantly
on
the
speaker
while
it
is
playing,
so
if
you
try
to
measure
DC
resistance
on
a
speaker
with
a
multi
meter
while
it
is
just
sitting
on
a bench,
you
will
most
likely
not
get
a reading
consistent
with
the
ohm
value
stamped
on
the
back
of
the
speaker's
magnet.
