TH, if you'll do as Bren suggested and use something like this (or even the plain brown stuff that I use)I promise that I'll protect you from the audiophile police. It might be helpful to study this explanation of speaker wire by a well-respected veteran audio professional.

The 174 wire you show is just single conductor power cable and isn't suitable for your use ; the 155 is okay if that's what you want, but it's a bit of overkill for the short runs that you'll have.
