Twisted coaxial interconnects… Interesting

 

It's somewhat pointless on unbalanced connections, but yes you can tie the braid at one end or alternatively give it it's own dedicated ground.

On pro level gear with balanced send, you have phase positive and phase negative then a dedicated shield with both ends tied.

 

That’s when twisted pairs make sense 👍🏼

 

I’ve always soldered my own RCA cables just like you pictured except I use Belden microphone cable because it’s shielded and thin/very flexible. The RCAs I use are Switchcraft.

 

Do you use quad star mic cable? Do you ground the shield or just leave it?

 

Here’s the finished product. Canare L4E6S quad star mic cable with Amphenol Gold RCA’s

 

You did this?

 

Nice work 🙌

 

VERY NICE !!! (In Borat's voice)

What did you decide to do about a shield?

The OE Bose in my 2011 INFINITI grounds all of the "drain" wires at the amplifier. The "drain" wire is just a bare wire that runs next to each signal pair from the headunit back to the amplifier in the rear.

 

I grounded the shield on one end like the image in OP

 

Nice, 3 of them split to aid bridging?

 

Yes, 2 for bridged midbass and 1 for sub

 

Sorry I stick to conventional schemes of making unbalanced cables(simple coax) which I was taughted for my proffession.
Must say I benefit a lot from reading Risch's articles so I shared it here for people like you who are more interested in this topic...

 

If i was using balanced cables for unbalanced signal lines, I'd be tempted to send the hot and ground down the twisted pair. Then use a solder sleeve with a embedded wire to tie the braid to a dedicated chassis ground. This is what the OEM do for crank and knock sensors.

 

I like the idea of making custom cables. Figuring out what to do with excess length is always a challenge, I figured homemade wouldn't be as good as some of the more pricey cables. Yours look really nice and that doesn't look too complicated if you know how to solder. How is the flexability of your cables?

 

I’d put money on these cables being better than any off the shelf car audio cables including Stinger 9000. Price of a single Stinger 9000 1.5ft stereo RCA - $130, my 7x 2.4ft RCA’s - $80 total.

As for flexibility, I’m using microphone cable so it’s by nature very flexible. I’ll post a picture later of how flexible they are

 

How do they sound? What equipment are they interconnecting?

Where did this diagram come from?

 

I don't know if any one has noticed but Resonix has DIY RCAs kits with coax wires. I'll be trying these next.

Saw them on Youtube when the video dropped. Neat concept, at first I thought they were too expensive. But after doing the math, it's not too bad.

 

I need 10 pairs and about 24', I like the black chrome but they are more expensive.

OMG, edit 2.

 

Yea thats gonna cost you more than double. Cuz it goes from 10' to 25' no in-between. And it's stange that it has 9 pairs I guess the amount goes up in multiples of 3. But it's really good concept and easy to work with.

 

It would cost about $215 plus tax and shipping. vs I normally pay about $30 per 3' RCA pair. (Stinger 8000 Series). So it would cost about $65 more than I would normally spend. Might be worth it as I can make the cables to length and make the install cleaner and easier. I'm a bit OCD about how my cables look and are laid out. I've done a lot for work lacing IT rack and datacenters, out of place cables or cables that are too long make me unhappy.

 

I'll be trying these out for sure. My plan is to completely delete my head unit and stream directly into an Amp/DSP. So I'll only need like a couple pairs in a very short length so it will work out perfectly.

 

today I ordered some canare l-4e6s cable and rean nys373 rca's for when I do my install

 

PartsExpress to the rescue for me…
$25 for 100ft of guitar/instrument cable and $1.52 per terminal. Cable is pretty basic, thick but flexible rubber on the outside, braided ground, single wire in the center.

 

Check the Parts-express ebay site. I've found a bunch of stuff thats a few $ cheaper than the main site
