I went to change the speakers out of my civic the other day, and i can't find a way to take the old speakers out and put the new ones in

.I looked for any bolts or plugs that can be removed from the trunk, and I cant seem to find any. I attempted to remove the rear speaker grill and almost cracked it in two... Im all out of ideas…. Iv herd that I might have to rip out most of the back to gain access to the rear speakers, but if any one knows an easier method plz msg me! Thanks!
