I need some cable raceways that are going to house a 12 guage wire and a cable for a sub. What size would be appropriate and were can I buy the most inexpensive ones. I need the raceways to have an adhesive back
I used some from Lowes. They come in separate pieces or in kit form. The kit is a much cheaper route to go if you need all or most of the included pieces. It is plenty large enough to house two 12g and sub cables. And it sticks. I misplaced one a tad off and when trying to pull it back off it tore off the drywall so make sure of placement before removing the paper from the sticky.
