Extension cords for speakers.

[Chynkinese]

Just got me a set of Logitech X-540s from Futureshop ($64.49CDN after price matching with Best Buy...SWEET deal!) and I want to mount the two back speakers to my wall but the wires aren't long enough. My question is..what sort of extension cords do i need? and what's the price range for them?

If it's only a few feet, just get some cheap speaker wire, making sure to
keep +/- the same. Keep in mind, 7.1 should have 2 behind you but with 5.1
the "rears" should be to the side or just slightly behind you roughly at ear
level when standing.

Is it the 3.5mm cables i'm looking for?
