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 wired in an string (end to end). A Parallel configuration
consists of two or more speakers wired with the common terminals con-
nected across each other. A Series-Parallel configuration is a combination
of both methods. Determine which method will be compatible with your
amplifier.
