If you can use the new plate in the stock hole, then you will be able to close up the bottom. That bottom plate when on.. may still allow you to run the wiring out the side even if you cant use the newer plate in the old plate hole. I think the plate has some areas that wires can be passed out of??
You certainly could cut the speaker to allow the NC plate to fit..but then you would be making a permanent change and I suggest this only if you are going to either keep the speakers or sell the speakers later with the XO's.
When I sold my pair, I sold them together, but offerd the buyer the option of taking the speaker with or without the NC XO's. I could have then reconnected the stock XO's and binding posts if necessary. You have to make that decision for yourself of course.
