Connecting Your Amplifier
Connecting Two Speakers in Series
Speakers are connected in series when the first speaker’s positive terminal is
connected to the next speaker’s negative terminal.
Note: Determine the total speaker impedance of speakers you want
to connect in series by adding up the individual impedances of all
connected speakers.
For example: If connecting two 4-ohm speakers in series, your total
speaker impedance is 8 ohms.
Connecting Two Speakers in Parallel
Speakers are connected in parallel when the speakers’ negative terminals are
connected together and all their positive terminals are connected together.
Note: Determine the total speaker impedance of speakers you want
to connect in parallel by dividing the impedance of one speaker by the
number of speakers.
For example: If connecting two 8-ohm speakers in parallel, divide 8
(one speaker’s impedance) by 2 (number of speakers). Your total speaker
impedance is 4.
