Wondering if the rear panel speaker inserts for an eg are the same size as the door speakers?

 

Well I read that they were 6.5 inches so I (without checking) bought that size RF power speakers all around, and they ended up being actually around 5.5 (i cut lines from the center out about an inch long all around the hole and bent those pieces of metal back to fit the 6.5's)

So you can easily fit 6.5, but i'd look for a good 5/5.5 inch speaker.

P.S. I don't know if it matters but my honda was canadian.

The speaker in the rear of the hatch.

 

5 1/4" in the rear, maybe an oversized 5 1/2"
