Make the speaker connections using speaker wire that is at least 16 gauge or heavier.
As with any audio component, proper phasing of the amplifier and speakers is essential for
strong bass response. When connecting, make sure that positive (+) from the amplifier is
connected to the positive (+) of the speaker, and the same for negative (-).
