Hi @jope123 ,
Most probably you will have to replace both the socket in the player and the plug on the cable.
Here is how they ''may'' be wired if Bose kept to the same arrangement in their players

Here are just two components that may be used as suitable replacements if the dimensions are OK as their electrical specifications are sure to be OK

If they are then search online for ''Molex (insert part number)'' to find suppliers.
If they are the wrong dimensions etc, search on the Molex website for more suitable components.
Hopefully a start.
