Cat 3 (aka telephone wire) is lower quality than Cat 5. Cat 5 has more twists per foot, and is rated to carry higher frequencies. For Wii use, I would expect the two of them to perform identically, given both are solid (not stranded). Cat3 would be easier to work with since there are less wires. Otherwise copper is copper at the same diameters. The wii cord is so tiny I can't imagine someone running into problems with stuff short of thin magnet wire. Speaker wire is rated to carry 100's of watts, so I'm sure it will work. The stuff in your walls carrying power (120v, 2400w) is probably 14awg. Speaker wire is usually 18-14awg.
At 6 inches away, it sounds like not enough power is getting through to the bar. If you're extending the wire, it may not be pushing enough juice from the wii or your power source to make it all the way through. Check your connections, use thicker wire (check voltage on the wire before and after to find your voltage drop), get an independent power source, or buy an aftermarket bar.
