Can component video cables be used as RCA's by using 2 of the 3 colors?? If so is it better quality?

Question

How much difference is there or can there by from one RCA cable to the next?

Answer 1

they are both 75 ohm unless you have custom cables from a company such as straightwire. they do optimize audio/video cables even changing impedance to achieve best results for certain applications.. but if they are standard cables you will notice 0  difference!

Answer 2

Do you mean "Can I use component cables for L/R analog audio?"

Yes.

Component cables are not really "higher" quality, they are just built differently for the higher-frequency video signals.

Audio signals are much lower frequency which make them a trivial challenge for any RCA cable.

Some companies try to scare people into thinking audio cables need to 'match' impedances like video cables do - but this is junk science.

All video output and input jacks must appear as 75 ohms of impedance.  The proper cable for video signals should be made with 75 ohm coax.  All video cables are made with this impedance.

But there is no standard for audio jacks.  You could buy a $300 uber RCA audio cable that is exactly 50.0000 ohms impedance, but the outputs of your CD player can be 35 ohms and the inputs to your receiver can be 55 ohms.  (As I said - there is no standard that audio has to follow).

As long as both the L/R RCA cables are from the same brand, model and length they work well for analog audio.

Answer 3

Sure, they are just sets of wires molded together. I use them all the time that way.

Answer 4

Component video cables are generally higher quality cables than those used for audio, but I don't think you'd notice any difference in audio quality between the two, unless you are superhuman.
