Guys I was looking at this cable http://www.audioadvisor.com/store/productdetail.asp?sku=ARIW1445&product_name=Pro%20Series%2014/4%20Four%20Conductor%20In%20Wall%20Speaker%20Cable since I plan on bi-wiring all of my Reference Studio speakers. My rear will be on the back wall and that means roughly 50ft (150ft total) of cable per speaker. If I get home depot 12ga then I will have to make 2 runs of 50ft per speaker (300ft). What do I do?????
