Thanks for reading. I am upgrading my front mains and planning on experimenting with a 4 rear surround setup. I was planning on running in a series, but I think this leave a ugly mess of speaker wire. My question is this, what would happen if I split the wire going to each rear speaker into a "Y" and run wire to the side rear and one to the back rear. I know ideally you dont want any spliced connections. I am more concerned about any impendence change.
