I use about 5 meters of similar cable with a crocodile clip on one end, that I simply hang around the room when needing better reception on my Eton receiver.
There is an old saying that the more metal you have in the air the better, but it's not exactly true. Even a few meters of wire will help transform a portable radios small telescopic antenna into something much better, but the bigger & better the antenna the more chance there is that you will over load the radio. So a few feet of wire, even if it is indoors, is sometimes the best option.
So yes to the type of wire & yes to the speaker cable.
What receiver do you have??

If you want to run a short wire antenna & get a small portable radio, attach the wire to the whip, not the external antenna socket if it has one. As some small radios attenuate the signal via this socket to prevent the radio from being over loaded. So with a short wire, say 5 meters or under , always clip the antenna to the telescopic, that way it will always improve the signal.
If you listen to airband then the Eton G3 could be an excellent choice, as it has airband (VHF) as well as LW to 30MHZ coverage on SSB/AM. It's what I use as my main portable & at around £100, you would struggle to find a decent 30 year old base receiver that works as well as this, for that money.

Try 49 meters..5900–6200 kHz There is normally something to listen to there at most times of the day. But if you are using a domestic radio with SW added as an after thought, you may not find many signals are any where.

If you don't mind using Java..Try The University of Twente's SDR online radio @ http://websdr.ewi.utwente.nl:8901/
Under the water fall set the mode to AM
Enter a frequency & zoom in.
You move the frequency you are listening to via your cursor & you may need to alter the band width, that the wide N thing, if you hover your mouse over the base of either side of it, it says "Drag to change filter.)
You line the centre vertical up with the vertical lines (signals) passing up the screen.
