What's the best way to hide the cables for my surround sound speakers?  

Hi, just went through this problem recently. Do you have an attic? If you do you could run them up through that. Our surround system is set up for wireless as well, so we could purchase the componet that will make it fully wireless as well.Check with the manufactuer and see if they have a router or componet that will convert it to wireless.
Good luck!
Have an AWESOME ONE!

At my home i do this in tow way's oone: in a room i have celling and i just get the cabele under celling tilles or in the other room parquet and i just go the cable on the edge under parquet and is hide perfect if you don't have a parquet or false celling u can buy some cabel chanell is about 0.5$/m and just mount in the bottom of the wall ...but disavantage ...is only white color beause is PVC...but is better then the have cables all around you to sttumble!

If you only have one level in you home, run the cables along side of a pieace of modlding. Or pull up a sid eof the carpet and stick it under it.
If you have a basement or an attic, drill a small hole adn run the cables through the attis or basement.
