To be safe you can hook up the speakers in series!
.
What Series Wiring Means
In a series configuration, all speakers are connected in a chain:
-
Positive (+) of the amplifier → positive (+) of the first speaker
-
Negative (−) of the first speaker → positive (+) of the second speaker
-
Continue this pattern for all additional speakers
-
Negative (−) of the last speaker → negative (−) of the amplifier
