Bose Model number would be helpful.
You will need a turntable with a built in phono preamp. If the speakers have an aux analog audio input you would need an adapter with 2 female RCA at one end (for the TT) and a male 3.5mm stereo plug on the other (for the Bose).
If not you would need a bluetooth transmitter to connect to the TT.
There are a wide choice ot turntables and most of the cheaper ones have the phone preamp built in.
