How do I set the number of speakers I use at the cafe store?

I'm thinking of starting a cafe.

I'm curious about the speaker part.

I'm thinking of putting special emphasis on music.

I'm thinking of using boss or JBL for the product.

I'm not sure how much speaker should be installed depending on the size of the store.

I think the store size is about 50 pyeong.
