Would using Computer AC Cords work as Speaker Wire?

Hack off the 2 ends, use the 2 wires that are used to carry the electricity and leave the earth wire unused

Update: Darn, found out most if not, all of those cords wires are 18AWG... Would using 2 wires for one polarity work making them 9AWG?

Why not just go to Home Depot or Lowes or wherever, buy extension cord and lop off the ends?

well, I have like 10+ extra ac computer cords, and if they would work they would look like some super expensive audio cable with the thickness of those cables and 9 AWG could be done for cheap

Assuming this idea works, so I was wondering what do you guys think about it?

Two 18AWG's = one 15AWG.
Four 18AWG's = one 12AWG.
If you do something like this (and I don't know why).
Connect all the blacks together.
Connect all the whites together.

The wire would work fine as speaker cord, however 2 18 gauge wires together are around 15 gauge, not 9 gauge. 4 of them together would be around 12 gauge.

Gauge is logarithmic, not linear.

OK, so you've got 10 cords. How long are they? After all, your speakers have got to be some reasonable distance apart. If the cords are something like 18 gauge, doubling up on them would give you 15 gauge. You know, sometimes in the effort to make something that looks impressive, you wind up making something that just looks stupid.

Aren't most computer power cords ~3-4ft long?

Thanks for the suggestions guys!

I'm actually planning to do these on a pair of Primus 160's sitting on my computer, gonna start this project soon!

Pics are coming soon!

Hmmm...

Hate to burst your bubble, but something like 24ga wire works just fine for a distance of only a few feet - although the smallest I'd ever use in practice is 18ga in a pinch, or 16ga.

Just because there is a knob doesn't mean you should turn it.

Pics are useless unless they've got a real hot legal age babe in them. Don't post them unless you can do that.

Make sure you twist the wires together.

On the subject of power cables, what about the low voltage lighting wire in 12 or 14 guage?

I was looking at speaker wire on Monoprice when someone in the office said to use that low voltage lighting wire instead. I killed them for reading over my shoulder, but now think they may be on to something.

Do you think there's s difference between 12AWG copper speaker wire, and 12AWG copper "landscape lighting cable"?

Absolutely! The low voltage cable is normally black, embossed with the notation "low voltage lighting" and will have thicker insulation for exterior use.

It will be entirely without sonic enhancing features such as separate stands for the treble, exotic strand positioning topology, and... well I would say more but it is time for another glass of modestly priced Sonoma Merlot.

The fact that an opinion has been widely held is no evidence whatever that it is not utterly absurd.

I was making a joke about the killed them for reading over my shoulder...ah nevermind.

I did go ahead and use the 12AWG Low Voltage wiring, but since it had the "course, thick internal strands" instead of the fine strands found in the million dollar speaker cables, and I haven't line conditioned said lighting wires, I am sure I am not getting the full dynamic range and spread spectrum ambiance available from my equipment.

LVL cable from HD makes great low power speaker wire for modest $$$.

For heavier duty use, I recommend #8 and #10awg zip cord from an RF supplier where I bought mine. I mention it in my blog and have a photo of the wire. It makes the ideal speaker cable and doesn't require a second mortgage to buy it.
