I have my speakers comming and I have to get some wire now. Because one of the speakers I have to do an extended run all alond the back of the house to reach it, so its well beyond the 48 feet they say for 16 awg wire. So do I have to get 14 and spend he extra money? dont know if it matters but I am running all tower speakers except for my center in a 7 channel set up. And my reciever is a pioneer sc-65. Thanks in advance for the help.
