Speakers are connected in series when the first
speaker’s positive terminal is connected to the next
speaker’s negative terminal.
Determine the total speaker impedance of
speakers you want to connect in series by
adding up the individual impedances of all the
connected speakers.
For example: If connecting two 4-ohm
speakers in series, your total speaker
impedance is 8 ohms.
