In short, running the RCA wires next to the power wire does NOT cause ANY interference whatsoever.  The power wire is carrying a DC current, which has a frequency of ZERO, and the RCA cables are carrying a frequency from 0~40khz.

These two wires will NOT cross talk as is the misconception.  How could they?  The power wire is putting absolutely NO interference due to the fact that its frequency is zero.

Interesting.  So the electromagnetic field it generates doesn't actually produce any interference?  Can you explain more about the "frequency of zero?"

I've never bought into the idea that power wires had to be run seperate from RCA's b/c I've never solved a noise problem by seperating the two.  Good to hear I wasn't just lucky.

I recently read a similar article about this as well. And there were other points brought up too. Here is some of it...

There is no where on the chassis/floor of the car that will be isolated from noise.

Electrons flow from negative to postive. There is NO way to isolate anything going down the power wire from anything laying on the chassis/floor. Because anything that is going down the wires is also going down the chassis.

You do NOT get noise (or any audible noise) from running power wires and RCAs together.

You do get noise from bad grounds, poorly designed equipment, or a pinched cable.

Running power wires and low level signal wires together will not have an effect on noise. there is no statistically reliable evidence to show that it does matter, but there is a lot of evidence available to show that it doesn't.

You wanna credit the source of those quotes, dwarren?

I'd be interested in seeing the whole article.

Merunning RCAs by power -- posted image.

It was discussed at work, however I am not necessarily agreeing or disagreeing with the given info. For me to buy this, I might have to try it.

Unfortunately some of this info was pulled from Rcichard Clark and David Navone, which in my book are circus clowns.

You used the wrong smilie.  It should have been a running RCAs by power -- posted image..                   running RCAs by power -- posted image.

No, stevdart I was graceful in my choice of smilies... Your purple guy was the wrong one!

To me it seems there are flaws to both arguments. But there shouldn't as these really are mathematical and technical expressions.

I have to disagree here.  Alternators produce rippling DC voltage because it can never be flattened out completely.  If you view this on an o-scope, it will look like a sin wave and will have a frequency.

I will agree that most of the time power wires will not induce any noise, but I, as well as others on here I'm sure have run into cases in the past where moving RCA's away from a power source solved a noise problem.

My ex once told me I have a perfect face for radio.
