What are 208 Speaker Dimensions?

Hi friends. I want to change the stock speakers of my 208 Active vehicle, but I cannot find the dimensions of the speaker slots. I do not want to remove the flooring just for measuring before changing it. When I look at the Service Box, diam says 160, is this worth in mm? I would be glad if anyone who has information informs.

In our vehicles, generally the front is 16cm, the rear is 13cm. You can also find it by measuring its outside diameter.

Service box says diam 160 for the back and the front. It is not clear from the outside, I could not get out of the work. Let me try and measure it again :) Thanks.
