Rear speaker deck swap

[Shown Jon]

can the rear speaker deck on a 2014 civic si or other years fit on a 2014 civic lx sedan. Am wanting the subwoofer speaker grill in the back of my lx so I can put a digital design sw6.5 sub in. I'm going to cut out the middle if the si deck will fit.

You don't need to ask the same question in multiple posts. Don't wast your time. Adding a free-air sub in the rear deck will not improve the sound quality or add any bass.
