Can running rca cables next to power cable cause distortion?

[QUOTE="n2audio, post: 8420116, member: 540940"] Power wire/signal wire location isn't the problem. But on that topic -- Theoretically, there is noise there. In practice it's not going to cause an audible problem. Current flowing through a wire generates a magnetic field around that wire. That magnetic field then induces a small current in adjacent wires. Years ago some super genius installer caught wind of this phenomenon and the "separate signal and power wire" myth was born and became a standard recommendation that is still popular today. Nobody stopped (or at least not long/loud enough) to realize that the noise generated in the signals wires would have to occur in the audible range for it to become an audible issue. It doesn't. There are plenty of noise sources in a car, but the power wire isn't one of them. An engineer at carsound once posted about TRYING to get power/signal interference by the above method and couldn't MAKE it happen. I did have a discussion once on this topic and it was suggested that an alternator with a big ripple in its output could cause audible noise which seems logical. It would be an exception, not at all a rule. [/QUOTE]
