Sort of depends on how much DIY you are willing to do.
If you have lots of audio odds and ends about (or access to such things via family and friends) then you may be able to create some workable combination of connections, amplifier, and speakers.
We have a local Goodwill store that always has all sorts of speaker(s) and speaker systems available. Plus lots of DVD, CD players with speaker sets. Generally very inexpensive and not much to lose if things go bad or blow.
Find out what wattage the speakers are so you do not overdo the power.
Read tutorials such as this one:
There are others such readings online.
Go back through this forum and read other audio postings. Folks such as americanaudiophile have posted all sorts of good information and guidance.
Work out whatever seems appropriate and viable for you. Then give it a try.
