A little help on sub cables please.

Rivrrat

I'm opening up my walls this week to run surround cables. I have 10b's in a 13x20 room, and I don't feel the need for a sub right now, BUT, just in case someday I want one, I want to place a sub cable while the walls are open.

Are powered sub cables just regular rca jack connecting cables, or are they coax with rca connectors? I understand they're passing a low frequency signal, but I want to use what's best.

I really don't want to have to open up these same holes for 3rd time, so I'd like to do it right.

Thanks in advance for answering a noob question.

It's a regular coax cable with rca ends.

For fun I've made my own with leftover coax cable and some screw-on RCA ends...

Wow, Willow, Canadians sure know how to have fun

Purely kidding, love my neighbors to the north.

Well I do that in between feeding of the polar bear and repairs to the roof on my igloo

You forgot about clipping the dog sled teams nails.:D

Thanks for the responses, and keeping a noob question light.

Now to shop. I'm glad my wife indulges me on some issues.

Screw-on as opposed to crimp-on? You didn't really use them did you? They're an accident waiting to happen. We use them for camera work and for emergencys only and then replace them with crimp-ons when we get them in stock .

Can you use a regluar RCA cable and use that for a subwoofer cable. I just want to hear my sub today. And I ordered my cables from Signal but they are not to be here until next week. I was just wondering if you can just split the R and L rca cable and just use one of them? I cant wait thats why. Is it going to break anything?

Yes, you can use a regular RCA interconnect. It won't hurt anything.

Willow, I'm in Dallas, TX. Nothing but Cowboy boots, hats, steer roaming the streets, etc. A day in my life is pretty much like watching Urban Cowboy.

Actually, a couple of my consultants are from Canada and we were laughing about stereotypes over lunch today. That's why I chimed in with the wise-crack. . . fresh on my mind.

Andrew, it's all good.....

As for the cable I made..Yes screw on types to a left-over long piece of coax cable had lying around the house....As far as an accident...the only thing I could see happen is that I **** my finger on the coax or the sound cuts out...other than that....It was an experiment that lasted ohhhh about 3 days.

Since subs tend to pick up hum (and have a longer cable run) sub cables are often a little better sheilded than standard RCA cables. If I was going to run one in a wall, I would get an actual sub cable, but in a pinch - standard RCA interconnnect cables work just fine.

The dreaded hum...Hmmmmm.

Out of curiosuty and because of what I do at work, has anyone tried to run a ground wire off the ring of an rca connector to a ground point to try to eliminate hum? We use a lot of shielded cable at work, and I'm figuring it should work the same way, but being new and all..........

In retrospect I'm thinking a standard interconnect wouldn't work (you'd probably just be grounding out the signal, if the ring is connnected to anything at all), but if you're using coax I think might.

Actually,I've used a standard audio I/C ,well,not exactly standard,to get rid of hum from 2 SRT subs,and it not only worked,it tighten up the bass.But for inwall,a well shielded cable is needed.
