If you buy anyhting other than welding cable, you are throwing away your money for an inferior product. As for RCAs, try and buy something of decent quality, if anything, it is because of the ruggedness you get... Stinger, Rockford and all the other main stream brands are super rip-offs, almost to the point of absurdity... Knu has some good deals, but, they cannot compete with the quality and durability of welding cable. To be honest, the best RCAs you can get for the money, hands down, are Dayton brand from Partsexpress. They are better than any of the car audio brands, at any price. No shit.
