I have the head unit for the Edison PSL5500 party system. I also have two speakers but no speaker wires or power plugs. I don't know if they work but you can have them too. One is missing one of the wire posts in back and one has a cracked lens on one of the front lights.
This is a monster system. Time for it to move on.
