Do you mean 24awg? If that's the case then it would probably be adequate if you used low power and the amplifiers were very close to the speakers.

If I may, while as a broad principle I absolutely agree with the points made above, Dave is also correct within certain contexts. For example, many (not all) Fostex drive units are overdamped assuming a more-or-less pure voltage source and were specifically designed to be used with high output impedance amplification. This is not a matter of conjecture: the man who was one of the lead designers on the old 'FExx6E' series drive units confirmed it when we met in Hong Kong a couple of years ago. Ergo, if your amplifier is inappropriate to the design intentions (output impedance in the approximate 1.5ohm - 3ohm region), then some series R, either with a fixed resistor or the distributed resistance of a narrow gauge wire / more resistive conductor will compensate. This is a somewhat restricted variation on the early days of high fidelity, when many amplifiers had adjustable output impedance to help optimise the electrical & acoustical system alignment.

Yes twisted pairs. Speaker cables can act as RF interference antennas. The interference sneaks in thru the feedback network to the input stage. It's something that Jim Brown sometimes writes about.

Unless you're running kilowatt power levels into 2R speakers, this is all you need:

It definitly does not hurt to own a 12gauge

Some of the better speaker cable I have used was some surplus commercial aircraft power cable. It was wound (twisted within the casing) to help reduce rf emission for it’s intended application.

I still have some but it’s not very practical to use, is very stiff and isn’t a pair.

I just use 16awg lamp cord.

Speaker wire
The best speaker wire I ever used, went direct from the amp to the speaker with little detouring, and had clean contacts.
Life is easy if you think lamp cord because no one can hear the difference with the boutique cables and if they do it's because of a problem with them, not the lamp cord.
Stop sweating what the SO'ers tell you.

Get out your antenna physics handbook. As Cordell writes "EMI Ingress: Antennas Everywhere" When you get into the MHz the cable, even connected to a loudspeaker, acts as a badly terminated radiator.

If connecting speakers in an average room, a length from 3 to 20 feet, standard 16 gauge copper "zip cord" is fine, unless somebody on the internet has scared you into using some kind of nutty expensive wire that you really don't need.
And there are tons of "snake oil" salesmen on the internet and even in stores - they need your money.
