Owner's Manual

Wiring 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.
Note:
Large Terminal
=+
Small Terminal = -

Wiring our 4 ohm Dual Voice Coil Speaker in series so the amplifier sees an 8 ohm
impedance:
Note: The following speaker 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 usat:[e-mail].
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.
