Follow these steps to connect two speakers in
parallel.
1. Connect both speaker’s negative (-) terminals
to each other. Then, connect both wires to the
amplifier’s COM terminal.
2. Connect both speakers’ positive (+) terminals
to each other. Then, connect both wires to the
amplifier’s speaker terminal (4

, 8

, or 16
Ω
)
that matches the total speaker impedance.

.
1. Group the four speakers into two pairs.
2. Connect each pair of speakers in series. If you
connected 8-ohm speakers, the total
impedance of each pair is 16 ohms (8+8 = 16).

If each of the four speakers
is 8 ohms, the total speaker
impedance of the combined
series/parallel connection
described at right is also 8
ohms. Likewise, the total
speaker impedance is 4 or
16 ohms if the speakers are
4 or 16 ohms, respectively.
