speaker wire - home depot?

[SrLoin]

Was looking at Home Depot for speaker wire and was wondering what would be best.

I'll be hooking up two E660s only at the moment so I don't think I'll be needing much.

For that short distance would 14 be best? What they had there is as follows:

16-2: 250ft for $59.97 (pre-packaged)

18-2: $0.35/ft
16-2: $0.47/ft
14-2: $0.53/ft (rated for in-wall use)

Would the 14 be the best despite being in-wall?
