My home builder left me with about 10" of slack on the in-ceiling speaker wires coming out of the wall. That is just barely enough the reach my receiver connections; they are a bit taut. Is there an easy way to extend the length of those cables so it is easier to hook up next time? Took me about an hour to hook up a 5.1 system because I had so little room to work behind the console/receiver. I have a new TV inbound and I'm going to have to disconnect the wires to setup the TV.

New wires would have been the best, but also a real pain to do.
Get some speaker wires of the same gauge as the ones, from your wall.
Buy some Heat Shrink tubing, that will go on very tight once you shrink-it.
Remove about 1 inch of insulation from the origin, and the extension wire.
Put the Heat Shrink tubing into one of the wire, about 2-3 inchs, does not matter if it is the original or the extension.
Place the 1 inch of the wires that the insulation side by side, wires should where the insulation start close to both wires.
Twist away.
Fold away from the wire that have the Heat Shrink on, toward the one without-it, then the other wire, so they face each other.
Work the Heat Shrink over this mess, to cover all the expose wires.
Heat-up the tubing, it will get nice and tight

This last step is better done with a heat gun, but can be done with a lighter, just don't get to close to the tubing (it will melt and go

), start with a few inches away, if too far and nothing happen, get closer by some small increment, when you it doing it-s thing, keep that distance and take your time.
Also it would be wise to do a few practice run, on some spare wires and tubing, this way when you attack the real thing, you had practice and no bad surprise.
Good luck.
