Wiring Configurations
Three configurations for connecting speakers to an amplifier
are Series, Parallel, and Series-Parallel wiring. A Series con-
figuration consists of two or more speakers wired in an string
(end to end). A Parallel configuration consists of two or more
speakers wired with the common terminals connected across
each other. A Series-Parallel configuration is a combination of
both methods. Determine which method will be compatible
with your amplifier.
