Wiring Configurations<br />

Three configurations for connecting speakers to an amplifier<br />

are Series, Parallel, and Series-Parallel wiring. A Series configuration<br />

consists of two or more speakers wired in an string<br />

(end to end). A Parallel configuration consists of two or more<br />

speakers wired with the common terminals connected across<br />

each other. A Series-Parallel configuration is a combination of<br />

both methods. Determine which method will be compatible<br />

with your amplifier.<br />
