Just go to your local Radio Shack or whatever you might have that's of a similar nature, and get some extension cables. Preferably individual cables so you can minimize the amount of extra cable sitting around. Connect one end to the audio plugs on the Wii, the other end to the audio plus on your receiver, and you're done.
Maybe this has been posted here already but....
The component cables sold for the wii aren't made to connect to other components that are more than a few inches apart. I want to run the audio cables to my receiver which is at least 6ft. away from my TV. (I have to plug the video into the TV ) The A/V cables that came with the wii can be separated. The component cables are bound together and can't be separated. Does anyone know of any other cables that can be bought for the wii that will work? Any and all suggestions are appreciated.
