I quite qualified advice is for you to stay away from the mains. What's more,   
   you can't just run that anywhere you want no matter where you are.   
      
   You want to extend those mains you need to know how to put pires in boxes and   
   all that.   
      
   If you do it after all that then you can just use regular [phone wire. You   
   should do that.   
      
   get a transformer, 1:1 would be good but rated for mains isolation just in   
   case and wire that to the speaker. The wires from the secondary should drive   
   another speaker. Nice thing about that is you can run those wires anywhere.   
      
   When you get to anything running off the mains you need to know how to deal   
   with it, maybe even run conduit. You obviously don't and I figure it is better   
   not to kill yourself.   
      
   Digikey deals there I think, they can probably hook you up with the   
   transformer for a few bucks. If not you got somebody there.   
      
   Just stay away from the mains. I work on that stuff sometimes and I have seen   
   wires arc and spark, and even burn. I have been shocked pretty good, but you   
   got 230 over there.   
      
   No matter what, stay away, you could kill yourself or burn the place down.
