^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
Sure you can.  Just wait till an electrical storm comes.  that Nice long
wire will eventually blow out the drivers on either end.  Your destruction
mileage will depend on intensity of the storm.  It may not happen for some time
but IT will happen.  

So if your gonna do it, do it right.      

>As for 2 wire, make sure it's twisted pair. 

^^^^^^^ Right on! ^^^^^^^^^^^^^^^^^^^^^^^^^^
Make that bad-boy balanced!
