Hi kuanjb,
Once you've got that cone tightened up to the spider, you shouldn't need to touch it.
As far as the wiring for the kit one goes, I ran the wiring across the spider leg closest to the control cavity and popped a 3mm hole into the very corner of the ledge the cone sits on to feed that little jack through.
Currently routing and filing out new holes in the body sides to house a fishman pre-amp and a battery case.
