Connecting Two Speakers (Bridged Connection)

If you are connecting only two speakers (left and right), you can add (bridge) the
power output of two channels (front and back) to produce the combined power
of both from each of the two speakers.
Caution: This is a bridged connection that produces 170 watts per speaker. Use
this connection only if you have high quality speakers capable of handling a pow-
er output of 170 Watts.
