Verify that you have connected the correct wire pairs to

 

 

the amplifier. Play something at low level through the

 

 

amplifier (for example, from a CD player or tuner).

 

 

Connect the test speaker in parallel with the malfunctioning

 

 

line. If the sound level has gone or is very weak, the

line has a short in it (possibly a severe scrape, pinch,

 

 

or staple puncture). If the sound level is normal, the

 

 

wire is open (possibly a cut wire or a missed connection).

 

 

Using the test speaker, move down the line and

 

 

test each connection/junction until you find the problem

 

 

and correct it. Observe proper polarity.
