I've just got two surround speakers for the first time, and I'm looking for the 'best' (ie cheapest/convienent!) way to tidy up the wires to the surrounds. At the moment, both sets of speaker cables are running down the left hand side of our living room by a large sliding glass door. I've considered some sort of plastic tubing from HomeDepot or wherever - run the wire through it, put the tube flush against the bottom of the glass door. I'm in an rented apartment, so I can't rip up carpets to hide the wires under etc. Any thoughts/suggestions?
