the front speakers are 13cm but sat in an oval mount which youll break to moddify if your that defo on changing them go for 17cm and make some proper builds

I had some Alpine SPS-171As in there and all I did was modify one of the holders that came with the speakers.

Just make sure they\'re not so deep they stop the window from going down
