Which cable


I have a Sanyo entertainment centre,  a quality all in one system with cassettes,  equaliser etc. I have expanded the system with some boom box 3000 bass speakers and I'm thinking of using some left over wire which I think originally came with the door bell. Do the other members think this will be suitable.

Why would you use such a low grade cable on that high grade system, are you nuts?
If the OP is serious please don’t be offended. My apologies. No, you would want a thicker gauge wire of 16 gauge. No need to spend much as conventional stranded copper, speaker wire is very inexpensive. Amazon, Home Depot, Best Buy etc...all sell it. 
Thank's for all your comments. Its a confusing subject as I was advised to purchase some Qued cable in my local HiFi store which was going to cost more than the entertainment centre.
Thanks for the link I have had a look but I'm pretty sure I need wire with some sort of plastic covering,  or does it not matter with speakers.
