Hey guys. I've decided I'm not happy with my rear speakers where they are (too close to couch), so I want to push them out a bit. However, the speaker wire for one speaker is just long enough for the position its currently in, and I already have the wire hidden away. Can I just splice in another piece of wire about 3 feet long? Will this significantly affect the sound quality? Is it safe to just wrap the strands together and then wrap it in electrical tape? Thanks, Ian C.
