Wiring Configurations
Three configurations for connecting speakers to an amplifier are
Series, Parallel, and Series-Parallel wiring. A Series configuration
consists of two or more speakers (voice coil) wired in an string (end
to end). A Parallel configuration consists of two or more speakers
(voice coils) 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.
