I moved into a house that has integrated speakers and need some advice on the best way to control them. Is this something I need an amp for?

I'm clueless on this stuff so hoping for some advice on a basic level. What type of equipment is best? I'd like to be able to control using my phone.

I'd also like to know if I can control speakers individually or is this a case of all are on or off simultaneously.

This photo is the cables to connect to.
