A:Answer Newer connections require t a type cables…the ones with the black and red red pins, of you on,y have speaker wire input…either attached to screws or push into hole with red or black clamps, you would have to cut the speaker wire and separate the red and black leads. Most likely not worth it. Or, see what type of receptor, input terminals there are in your older system and see if there is a connector to that type to rca red and black. Good luck
