Runnig cable under carpet is a huge pain in the rear. If you are on a crawlspace it would be much easier to go under the house.
Another option is to use small AWG (16/2) wire that can be tucked between carpet and baseboard. Generic 16/2 is often enough white just like most baseboards.
Otherwise there is a flat option from most all manufacturers. These are difficult to work with becasue they never want to lie flat.
IMHO it is not worth $$$ on wire for surrounds.
Good luck!
