| One speaker still | Try connecting the speaker that does not play to the other speaker | 
| does not play | cable. If the speaker still does not play, the problem may be with | 
| 
 | the speaker. If the speaker now plays, you know the speaker and | 
| 
 | the cable are both good. Disconnect the cable from the ampli- | 
| 
 | fier terminal, and connect it to the other terminal connector. If the |

| 
 | channel of the amplifier. |
