How to remove rear speakers in '99 Coupe?

[Alpine]

I notice the stock rear speakers are 6x9 in size. I have some old Kenwood 7x10 speakers I wouldn't mind putting in its place (nb - the 7x10s are supposed to fit in a 6x9 enclosure). Will this be possible? How do I remove the rear 6x9s - the grill does not seem to pop off nor are there any visible screws from the bottom. The car is a '99 Civic Coupe.

I dont think 7x10's will fit.....I also had kenwoods 7x10s, it didnt fit. You can make it fit with abit of custom work, but i couldnt be bothered

For the rear, I had to remove the rear panel it comes off including the grille, and too make things easier, i just removed the rear seats as well.....(dont try to pop off the grille...coz u will only damage it)...doesnt take that long
