Hi, While this is one of my first posts, I have read quite a bit on these forums and have learned quite a bit. My question today is this: I recently bought my first house, and need a lot of speaker wire. My dad has access to a lot of 12ga automotive wire and he believes it would be a good substitute to the wire I was going to buy at home depot. He thinks the strands of wire are a bit thicker then the strands found in speaker wire (but his knowledge may be outdated). Will I loose anything by using the automotive wire, or should I go out and get the roll from Home Depot? If it helps, I'm using 4 Harmon Kardon HKB4 speakers and 2 HKC speakers, with an older Yamaha RX-V540 receiver. Thanks for your help!!
