Check The Connections; Test The Speakers - Bose 141 Series II Owner's Manual

Check the connections

Check to be sure all connections are made positive to positive (+ to +) and negative to
negative (– to –). Make sure that no loose strands of wire touch across terminals. Loose wire
strands could short circuit, which can result in electrical shock or damage. Tighten any loose
connections before you plug in the receiver or amplifier and turn it on.

Test the speakers

To make sure your speakers operate correctly:
1. Set your receiver or amplifier to MONO (monophonic) and turn it on.
2. Set the balance control to normal (center position).
3. Place the speakers less than 6 inches (15 cm) apart, facing each other.
4. Play some deep bass passages of music through the speaker.
The sound should seem to come from a point between the two speakers. The bass should
be full and natural. If it is not, your connections may be out of phase. To make them match
connections to the amplifier, try reversing the + and – connections on the back of one
speaker. Then repeat steps 1 – 4.
