I was talking to someone yesterday on the phone about rca gauge size and I mentioned I was gonna a use some spare 12 gauge silver plated wire to make my rca connections and trim what I need to fit into locking rca plugs which max size seems around 16 gauge I’m gonna get and you know heat shrink everything that will protect it etc etc. I realize it’s over kill and yes it is all short lengths from dsp to amps no hu involved.

He educated me about having to high of a gauge size for rca will yes lower resistance it also he mentioned other things about independence and I think ohm load carry maybe voltage as well? I can’t remember honestly. And I thought rca was nothing more then just signal passing thru from what I have read online.

Forgive me for not going into detail because I am a little confused in this matter tried searching on Google for this matter and couldn’t find a answer. I am just trying to understand they details of why this is bad to use to big of a size for rcas for education as well as decisions on proper wire gauge size for rcas.

Not lookin for answers about quality of rcas just mainly wanting to understand why having to big gauge size for rcas is such a bad thing to do? Asking for a detailed description or even a link on here or somewhere else to mainly understand

J-Fkn-C... the input impedance into modern amps is 10k to 200k ohms.
(a 26 gauge would be overkill.)

“skin effect” would be a better argument for one gauge over another... and that would support a smaller wire as well.

but maybe he is right... (it would not be a she to make such a claim)

Cable capacitance? I remember hearing that some home amplifiers, possibly Naim but maybe others, don't react well to cables that have a high capacitance. Not sure how relevant that is for your application though.

So is it gonna be a issue if I use the 12gauge and trim it to a 16 gauge ? Like I said I already have wire and I’m gonna use it because I’m not gonna spend more money buying more wire.

Nope, use what you have.

Just made these because that’s what i had on hand.

Will it sound a whole lot better then these probably not, but at least they will be cut to length.

Isn't "skin effect" the reason audio cabling in general has smaller and more numerous strands than the same gauge standard wire, less depth+more surface area=less inductance?
Wikipedia link for those that don't know what "skin effect" is.

Is that coaxial cable? If it is, the 12 gauge sizing is likely the overall diameter, which makes this discussion pointless. If not, let us know if you get any noise. Twisted pair or coaxial is the best construction for rca cables in any case.

Not the op, I presume he has 12g speaker cables or something 🙈

the ones pictured look far smaller than 12g especially considering he has two cores in that little 4mm diameter bundle with dielectric as well

Oh damn, I got lost.

Not my discussion but yes it is coax.

If this is 12g speaker wire, which it probably is. I would recommend something else that’s twisted and has some form of shielding. The wire gauge isn’t the issue even though it’s certainly overkill. It’s more the chance of picking up interference and noise. That being said if you have the ends and the wire, go for it and update us if issues arise.

Capacitance and inductance will be way out of balance… there is a reason rcas have decent sized dielectric and low conductor sizes to get low capacitance and reasonable inductance and low resistance
Yes this is what the guy was telling me but I need you to dumb this down a little bit for me so I can understand better of why this is bad I want to understand

Canare Star Quad microphone cable is under $.50 a foot. Why put yourself through the brain damage to save a few dollars?

I want to understand the difference of what dumdum said not buying cheaper wire to save money. This is a knowledge thing for me more then it is about money. If the situation is necessary then I will make the decision to change but why would I spend money and let my other wire sit around? Seems kinda dumb to have more stuff then I already have I’m not running a car audio shop man I don’t want more stuff

Capacitance blocks bass, inductance blocks highs.
