Flexible tubing to organize wires behing tv stand?

[Phatferd]

I was thinking of a way to minimize the the clutter behind the TV stand where I have multiple power cords, speaker wire going every which way and a surge protector, etc...

I was thinking of using clear flexible tubing to run the speaker wire through (just behind the tv unit so it's not so cluttered when I try and unplug/plug stuff in and out). Once it's away from the stand I will run the speaker wire under the carpet or on a wire track.

Here is the type of tubing I am talking about in case you're lost (this isn't the exact one I would get, but it's the best one to show what I am talking about).

Is this a serious no no? I have no idea and that is why I am asking. I'm afraid the heat put off from the back of most of these electronics may cause the wires to melt together or something...

I was also thinking of getting like a 2-3'' one and running 2 power cords through it to condense the mess, but am just not positive if this is a serious hazard.

Thought I would ask someone on here who is knowledgeable on these things, since I am obviously not.
