Wiring Configurations - Rockford Fosgate RFS-1408 Installation & Operation Manual

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 connected across each other. A Series-
Parallel configuration is a combination of both methods. Determine
which method will be compatible with your amplifier.
