Details Concerning This Item

I am considering buying a pair of front speakers (not the ientire sense surround system) to connect to the bravia DVA DZ170 they belong to, but didn't came with. 1. Would I be able to find the jacks somewhere to plug into the unit? the only offer I found doesn't specify the speakers would come with the original jack connectors. 2. Would I be able, once I find the right jacks (if they are available anywhere) to connect another standard pair of loudspeakers and obtain sounds out of them (possibly hi-fi correct sounds corresponding to the DVD played, the only function I am really interested in from the unit I have)?Thanks for your replay
