From what I can see your stereo system has:-
two pos and neg sprung clip type connections for your front L&R speakers
two RCA jacks for accepting optional rears L&R
one jack (possibly RCA) to connect a subwoofer (which must have it's own integral amp and ac supply).
If you want to make it work cheaply with two additional surrounds I would buy 2 surrounds with the connectors already on rated at 50 w 16 ohm impedance (similar to Aiwa SX-R220) . You can get them on ebay for buttons.
Proprietory 'audiophile' speaker cables normally have + and - markings on them,but you may struggle to identify the polarity on yours....sometimes the pos side is identified by a raised ridge running down on side or if you get the magnifying glass out you may find a small + mark printed on one side.If you can identify the polarity then you have a chance with the methods bobtomay describes.
