Rear Speaker Grills
 

Do the speaker grills come off the rear deck? If the Kappas don't fit because they are too tall I was thinking maybe I could take off the grill

The rear grills are attached. If you remove them it may look odd, you shouldn't have any fitment issues though. The only thing that may hit is the tweeter which won't matter anyways.

Yeah I was going to replace them with the supplied grills and it would probably look weird huh. I wish the sound streams were 3 way and not bi-amped :( I guess I'll worry about that after the other two installs are done.

You probably won't notice much of a difference between a 2 way and 3 way speaker.
