best place to mount crossovers?

the xovers are pretty big. i was thinking of drilling a hole and letting them sit in the door pocket. what do you guys recommend?

I mounted mine in the doors just above and tot he right of the speakers. I did have to cut out the plastic rings that are on the door panel to fit the larger speaker and used a 1 inch speaker spacer. Depending on how big your crossovers are it should fit next tot he speaker. I have also seen other members take out those foam filler pieces in the door panels and put them there.

i went under the front seats,
