So I Kracked open some Krystal RCA Kable

I think the extra layers of sheilding are picking up the noise rather than rejecting it, unshielded twisted cables were shown a long time ago to be the best for noise rejection in the automotive environment.

If you think I am promoting my rcas in this thread it was merely by accident. I have received multiple PMs with request to make them cable. I denied a few because I just dont want to deal with it. And my new cables did solve a majority of the whine(as did other members who posted who used a different brand as well).

on a coax that foil/braid touches the outer diameter of the connector. it does ground, as you said when you remove it from that part of the connector then it acts as an antenna..

when you strip a coax cable whether it be rg59 or 6 you would peal the braid back some and then insert connector than a metal sleeve behind it and crimp it.

I am not trying to go out of my way to "promote" myself, I just looked at the cable and was like wow.

btw the connectors keep coming off when I had them hooked up.

Sorry I was not clear - use a coax wire (not cable - cable I guess implies it is terminated) without any termination - insert the bare center conductor to the ANT, the ground is isoloated - it will not pick up the signal if the shield is covering the other end.

What gauge wire are you using in the new cable? If it has a higher resistance then our cable, that could make the resistance in your RCA higher then what the Headunit-to-chassis ground is and help alleviate the noise. It could hurt signal in return though.....

He makes custom RCA's, but for a long time he sold them for what it cost him.. I talk to him on a daily basis and it was no means how he put food on his table.

Personally I dont see why you wouldnt ground them as it wouldnt take much at all.... but these are entry level cables arent they?

its a 24guage just by eyeballing it. As you said before voltage is low, and no current draw, no issues on that, especially in such a short run. Do you plan to ground the cables on your new lineup/shipment, id really like to see this improvement?

Krystal are not a coaxial geometry cable. The Klarity, Karma and eKs all are and the ground is the shield on those with the eKs using a directional ground drain. The Krystal use a different design to be different from the others and they have worked well. The next redesign of that model is not to be released till 2009. The Klarity will get new look then a new Krstal line will be released

You mention the connectors came off, the ends are crimped onto the legs. The only way they come off is if you are not pulling them off by holding the barrel connector and breaking that crimps bond

I forgot to mention the internal conductors are 21.5 gauge on the Krystal RCA. If you are using 24 gauge, that would have a higher resistance then our cable, there by altering the path of least resistance by changing the cables, thus shifting the noise level but in turn could be hurting frequency respsonse with a higher resistance.

hey knuconceptz im a noob

so i was gonna buy some rcas off your site

which one would i pick for a mono amp?

Klarity Kable Y adapter 1F2M RCA Kable

Klarity 2 Channel RCA Kable 1M

its all confusing to me

i love knu wire ive been using for 4-5 years never had a problem ( well except the wire fades but after 4 years most do)

keep up the good work

not to bash knu i had some probles with their distro blocks. (but since he did hold up to the bargin When mine melted) . I trust and use alot of knu products. yes ive had my share of bad times with some of their stuff. but simply put . i dont think their is another company out their who is as good for the money as knu. like i said till this day i would use and fully endorse their product. And i aint sponsered either but their product is awesome and will continue to use it

im sorry I worded that bad. I meant they would not stay on the amp, I could easily slide them off. Could be an eD problem though.

I really doubt that. With the amount of voltage running through and little to no current going through, I really dont see an issue will occur. heck i even ran video through the same gauge cable before, I didnt see any video compromised resulting from this cable or that cable.

I dont claim to have golden ears or eyes for that matter lol but I would really like to see your shields grounded in your next line up even if I have to wait until 2009

Most mono amps still take a 2 channel input so any 2 channel RCA would be good for the application. Make sure you do get the right length:

1 meter = 39" so for most cars a 5-6 meter cable is used.

As for what series should you select, that is really based on your preference of cable types, what style appeals to you, and of coarse budget. Its why we offer the various types of cables, not everyone wants the same thing.

so you do not think 24 gauge has a higher resistance then 21.5 gauge? We'll have to agree to disagree on that one //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

Got to run - I'll check back later

 

[Megalomaniac 5,000+ posts]

not what I said at all. o man.

Im saying it is not a significant difference at all for that length.

I have used a 26awg Canare rg59 before on a 100' length crossing many ccu ,power, unbalanced cables before, I saw no difference. Even then resistance comes to play major only on a long run, and 100' run is not considered a long run at all
