If the amp is too powerful, 125hz for a 4" speaker.
Else 100hz should do.

Its better to get 6.5" compos rather than 4" IMHO.

will 6.5" will work better than 4" in HPF ?
i think they both will be same as there is not bass from the speakers. its just the vocal and treble comming form the compos.

For a 4" speaker set the HPF to about 125Hz/12db for a 6.5" speaker you can get an octave lower (63Hz/12db).

Even under these circumstaces you might find the 4" "giving up" before the 6.5" does.

thats ture about 4" giving up if compared to 6.5", i really dont want to cut the doors. or i can use the rings to install on top of the stock location but will look ugly and pagli.
is there any way of holding the 6.5" under the dash some where, while facing to wards the passenger or up like the stock position?
