Im debating whether to buy speaker wire for a set of brand new speakers.. The speaker wire i have now is about 6 yrs old, non-oxidized flat and braided copper wiring.. Radio Shack brand lol.. The speakers im getting are a pair of cerwin vegas, 300watts peak, speaker length to reciever no longer then 6 ft for left and right speakers.. I dont even know what gauge size i should get..I was thinking of the speaker wiring sold in the Audioholics online store.. Any ideas?.. Thanks in advance..
