speaker's impedance.
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.
