You’ll need an amplifier like this

Look behind your speaker to see the power of it (in Watt [W]) and search an amplifier with enough output power. This amplifier as a 100W output for example.

And to connect the speakers to the amplifier you’ll need this type of cables

And then you can play music via Bluetooth or, if you have a mini jack, you can use that type of cables Hope I helped !
