Question with Wiring.
So my front passenger side speaker only works sometimes. It doesn't cut in and out when I'm driving, but it'll work for a few days then cut out for a few days. This has been consistent for at least a month, so it's getting pretty annoying. I've pulled the panel off the door and checked the speaker itself, and pulled out the radio and checked the back connections. I noticed there was a wire that looked different from the rest. It was blue and shiny. So naturally I took a look and it's a wire that's covered with foil (silver on the inside and blue on the outside) but it doesn't connect anywhere. I'm not a pro at this, and I don't know what that wire is, but I wrapped the foil back around it and taped it up with some electrical tape to make sure it's sealed.
I have a picture but I can't post it right now because I'm on Mobile.
Does anyone know what the hell that is? What it does? I've searched all over the internet and didn't find anything.
