Best CHEAP long under-carpet speaker cable

I use Acoustic Research 16 guage 100% pure copper wire for my surrounds, it has 4 runs and is about an 3/4inch wide and very thin and it cones in white. And it is cheap.

I thought the Mapleshade wire is a bit on the delicate side. If the carpet that covers it is to be walked on, might this create a potential problem?

So far no problems here. I had the Mapleshade cables for a few months under the carpet for my surrounds. I ran it along the edges and is under a thick 10 lbs carpet pad with thick carpet on top of that. So there is lots of padding. Works for me and sounds great. It is a little delicate and you have to be very carefull and tape it to the floor before laying the carpet and pad on top.
