Hello, I'm sorry if this is a silly question, I know almost nothing about this field. I have an old receiver with multiple RCA inputs for various items like a turntable, etc. It is connected to a set of speakers. I would like to connect to this setup a newer item that has no output. It is a CD player/bluetooth stereo. The only thing it has is a place to attach the speaker wires to. Could I convert some speaker wires to RCA connections, and plug that into the old receiver? Thank you for any help or suggestions.
