the receiver/ampliﬁer channel and reconnect it to a different receiver/ampliﬁer channel.

component source of the music, or the connections between the receiver/ampliﬁer and the

source. Check all of those to make sure they are performing properly. Reconnect the speaker

to the correct channel of a functioning receiver/ampliﬁer.

the next instruction.

Disconnect the cord from the speaker in question and reconnect it to the second speaker.

dealer, who will arrange for service. Or, to contact Bose directly, refer to the

address list included in the carton.

– If the problem persists, its source is the speaker wires. Follow the next instruction.

Before you take steps to replace and re-run the speaker wire, recheck all of the connections.

Then repeat the procedure for pinning down the problem source, above.

Check the connections at the speaker and at the receiver/ampliﬁer. Make sure the wires are in

good condition, are ﬁrmly connected, and no wires are touching across terminals. Also check

the connections from the receiver/ampliﬁer to the component source of the music.

– If the problem persists, follow the troubleshooting instructions for "Only one speaker still

plays," above.
