the RED "positive" (+) terminal of the LEFT speaker to the RED

BLACK "negative" (–) terminal of the LEFT speaker to the BLACK
"negative" (–) terminal of your amplifier's LEFT channel.

the appropriate amplifier channels. Make sure that no bare wires from
any of the connections touch any other terminals as this could cause a

Amplifier Requirements — Klipsch speakers are highly efficient and
will operate easily on a wide variety of amplifiers. All Klipsch speakers
are 8-ohm compatible and can be driven to very high levels with low
distortion. Due to the high output levels Klipsch speakers are capable
of reproducing, exercise caution with the volume control. Excessive
volume over long periods can permanently damage your hearing.
Overdriving your amplifier could also damage your speakers. Check with
your dealer or amplifier manual to make sure your particular amplifier
is best suited to your application. We want you listening for a lifetime.
