Connecting Two Speakers In Parallel; Unbridged Connection - Radio Shack 32-2055 User Manual

The Basics

connecting two speakers in parallel

Speakers are connected in parallel when the speakers'
negative terminals are connected together and all their
positive terminals are connected together.
Determine the total speaker impedance of speakers
NOTE you want to connect in parallel by dividing the
impedance of one speaker by the number of
speakers.
For example: If connecting two 8-ohm speakers
in parallel, divide 8 (one speaker's impedance)
by 2 (number of speakers). Your total speaker
impedance is 4.

unbridged connection

Use this connection if you are connecting more than one
speaker on the same channel or if you do not have high-
power speakers.
1. Connect the speaker wires to the corresponding
left and right positive (+) and negative (–) speaker
terminals.
2. Connect the other end of the left and right speaker's
positive (+) and negative (–) wires to the amplifi er's
corresponding SPEAKER LEFT and SPEAKER RIGHT
terminals for each channel. To connect speaker
wires to the amplifi er, turn the knob on the terminal
counterclockwise until it stops, insert the bare wire
inside the space between the knob and the amplifi er,
then turn the knob clockwise until it stops to secure it.
3. Make sure the STEREO/MONO switch is set to
STEREO.
