   Give us the make and model number. Do you have the manual?

   I'm presuming these are the rear surround pair.

   Means nothing, except charitably maybe that at least the speakers are   
   connected to something and not floating around in the wind.   
      
   (If you had properly wanted to test the speakers are connected, a better   
   check would have been to disconnect each in turn from the amplifier and   
   with your meter do a resistance check across the leads. It should   
   measure whatever ohm figure is printed on the back of the speaker.)   
      
   Some surround systems have a test mode, to make a small noise from each   
   speaker, one at a time. Have you tried this?   
      
   There are many surround encoding schemes depending on source. And   
   special effects from your amplifier, and yeah maybe simulating rear   
   surround - how are we to know you have correctly turned that function on?   
      
   The comments posted by other respondents are entirely valid. You have to   
   help people to answer you, not imagine they are mind readers. Give   
   useful information - make/model is a good clue, and go find that manual!
