Has anyone here installed the rear speaker enclosure? I have a few questions for some that has.

The repop does not match my bottom holes at all. So I'm a little confused with the bottom lip. Does it turn up and under or turn out from the enclosure.

If the bottom lip turns up under the enclosure, that would mean that the bottom screws would have to go in first, then install the speaker on the enclosure and then install the top screws. Bottom screws not seen.

If the bottom lip turns out from under, the speaker can be installed and then attach the enclosure. Bottom screw can be seen.

Here are a couple pictures. Does anyone have a clue?
