Can I use 24 gauge speaker cable?

If you're using 24AWG ethernet cable there are 8 wires, using 4 wires each connection you have an effective AWG of 18. Should be OK with 3 watt amp. I made cables from ethernet wire but I used two and twisted all 8 for each connection then put them through a fabric sleeve for looks. 

When I saw this discussion come up on my email, I thought great, let's see how thoroughly confusing some of these responses are going to be.  Well, I haven't been disappointed.  Assuming your question is a serious, although many of these guys are correct in most ways, you best most useful is probably from caykol, above.  Just follow his advice and any others of a similar nature and you will do just fine.  As an example, a number of years ago, I moved into a new place and found that my old bedroom set up would not work in the new bedroom, so I went to my local HD store and bought 100 ft of 14 ga stranded cable, cut one the required 10 feet and the other had to be run out to about 20 ft.  At first I was worried that the difference in cable length would create an unbalance in the sound of my two speakers, but guess what,  I had a balance control, so after a couple of adjustments it worked just fine.  My main system, on the other hand, that only has one chair, is another matter.  Hope this helps

@dadork -

@williewonka Excellent response and explanation. I’ve bought cheap wire before and have upgraded to something much better but have never really understood most of the aspects you describe.

Many thanks for the kind words :-)

I actually make my own cables from the ground up because I am frugal and like you, do not have the thousands of dollars to spend on, as some would put it, "high price jewelery"

My speaker cables currently cost around $400 for a 10 ft pair to build and are preferred to top of the line cables from companies like Nordost and InAkustik i.e. by others that have owned those cables.

If you are interested to read more on them - take a look of this thread

It goes into a lot more detail on these cables and how to build them.

BTW - with DIY - you can elect to use whatever grade wire you like
- my early prototypes used household Romex and telephone wire to prove the concept
- the latest use more advanced/quality wires to achieve superb sound reproduction

I have spent the last 6 years delving into the science of cables and developing the Helix geometry for Speaker, interconnect and power cables.

The improvements due to wire type and insulation used is the latest development and was assisted by others from several countries that have tried the Helix geometry with many different wires.

Better yet, if you can borrow several different manufacturer’s speaker cables instead of raw wire, compare those as well. That way, instead of relying on someone’s opinion of what you can or cannot hear, you’ll know...

Perhaps the best advice on this thread to date !

It is EXACTLY how I started my cable journey - I trusted MY EARS !

Then my inquisitive nature got the best of me and the rest is history :-)

Hello,
Just like a few have mentioned in this forum or post. You just need several strands. 24AWG Cat 5/6/7 is really good because it is already twisted in the sheathing. You should do about 8 strands per termination. You can terminate them with some banana plugs or even better spades if your speakers can take spades. If not bare wire is the best but the ends will corrode over time. So give yourself about an extra 6” for cutting for redoing the ends every year. You might be supposed how good it sounds. You will get lots of detail. If you want more mid-bass double up on the gauge. Final thought: if you are using non twisted pair then watch videos on how to braid wire to help prevent noise and cross talk. I used very lite gauge wire in the past and it ruined one of my channels on my AVR. Just work your way up to 16 AWG and you will be good.
