When I first hooked up my ht system I was running my speaker wire to the back speakers through the attic. My wire came up a little short. I found some more wire and spliced(twisted) it to the other and put electrical tape around it. So basically its in two sections just put together. It may even be different guages. Am I screwing anything up by doing this. If I have to replace it can I just use regular 12 guage speaker wire? Thanks.
