RCA Noise

because he's smart enough to recognize it doesn't apply in this situation
not to mention - he's smart enough to know which "type" of cross-talk could theoretically be an issue.

Why would this not apply? care to elaborate on the "type" of cross-talk that could be an issue?

I am not trying to argue with you, I did a lot of reading on electrical systems and I don't understand how this isn't a problem. //content.invisioncic.com/y282845/emoticons/confused.gif.e820e0216602db4765798ac39d28caa9.gif

You said in the other thread that there would be current going threw the chassis which I agree with you that there is but I don't think there is enough current to make the chassis a source of cross-talk.

Thanks

You don't think that there is enough current going through the chassis but you believe that the power wire is different? Interesting considering that probably 90+% of people use the chassis for a ground meaning that every bit of current that flows through the power wire must then flow through the chassis. Add in the current from the other electrical components in the car that also use the chassis as the ground and more current flows through the chassis than the power wire.

Cross talk occurs between two signal cables. Signal, meaning AC. The power in your car is DC. DC will not induce noise in an AC signal. Induced noise is caused by a fluctuating EM field. The EM field around you power wire will change in size, but it won't reverse in polarity which is what is going to be required to cause EM noise.

I grounded the RCAs to the HU...worked like a charm. Still some white noise, so apparently I need better RCAs, but the squeel is completely gone and I can only hear the fuzz when the music is off. I had to wrap the ground around each RCA, because apparently the ground wire they came with is just for looks...

your RCA's came with a grounding wire???? shit no wonder they did this lol get better ones

I know, I will invest in some nice ones now...the ones I have look expensive, but are apparently shit

Grounded RCAs aren't a bad thing. If you'd properly used it the ground wire would have done exactly what you needed. What RCAs are they?

The stiatic is not from the RCAs either.
