I installed my crossovers in pretty much the same place Aitch mentioned. Used some Velcro to adhere the crossover to the composite piece, works well. If you have large crossovers, you may need to remove the circuit board from the casing to make it fit; if you do that, make sure to wrap the board in several layers of electrical tape to keep water out.
I actually mounted mine under the passenger seat where the amp for my fronts is. Partly for convenience in adjusting settings on it, also because in the manual for my speakers it says in big bold DO NOT MOUNT CROSSOVERS INSIDE DOORS, i think for moisture reasons. Here is a pic of them under the seat with the amp, the only disadvantage was i had to run two sets of wires to the doors from the amp, not a big deal though as the car was stripped bare anyways.
You need some pretty small crossovers to fit them in the door. I had to cut a bunch of structural plastic out of the door panel, including one of the mounting fasteners. The aforementioned spot is about the only place they will fit. I used sheet metal screws to affix mine, since other methods have failed in previous builds. I have pics at home, maybe I'll post them later. If you don't mind figuring out how to run non-oem wires through the doors, under-seat mounting would be a better option.

ya im not sure how accurate that is as far as danger from humidity, maybe just a small once in a while thing they have to mention lol. The crossovers for my speakers are really big though too so that was another reason
If you do decide to put them under the seat, let me know i have pictures of how i ran the new wires thru the door.
i kinda wondered why people mount adjustable x-overs where you can't get to them (easily). Kinda makes me wonder why they make em adjustable, unless it readily apparent how it's going to sound and which settings are best, before it all put back together again.

Eh, it's easier to remove the door panels than it is to wire two speaker wires through the door conduits. Yeah, that's what I'm going with :lol:
That's totally valid! The worst part of the entire install I did was running the new speaker wires thru those grommets!
