Remodeling our master bedroom and have a Sony 5.1 surround system. For years I had the rear channel wires running up through the attic and down a closet wall and along the baseboard to get it to the rear channels, but never cared for that arrangement. Now installing new carpet, so came across the very thin 4 conductor stick on wire from Monoprice, and ordered a 25' roll with the suggested 42163 connectors. I only received the wire, as Monoprice could not fill the order for the connectors for some unknown reason. I decided to try and give it a go connecting the wire directly to my spring action wall mount speaker receptacle from behind. It worked out quite well, I was able to strip the flat wire, fold it in half and get it to slip in directly to the wall spring connections from the back side. The hardest part of dealing with this wire is separating the insulation layers from the copper.. I used a sharp carton knife and lots of patience to separate the layers, but not easy. However, it worked out great, and no need for connectors. A side note, you can solder to the copper strips, but I quickly abandoned that idea as it would have been much more work and unnecessary. I just ran the wire into the wall and up to the connectors directly.
