Door speaker size?

Right im sick of only having 6x9's in the rear & no sound up front! So time to put some speakers in. Im just going for good sound, Dont want a big heavy sub.

Dous anyone know the size of the front door speakers? Ive read that its 6.5" but you have to cut the bottom of the door card? if you put aftermarket speakers in? Is this true?

& also has anyone had a problem with depth of the door? These are the speakers im putting in http://www.jlaudio.co.uk/c2-650x-car-audio-c2-coaxial-systems-99618 but worryed about the magnet being to big? Or is there abit of clearence in the doors?

not sure of size but mine are aftermarket front speakers and the bottom of doorcards does stick out from the doors but only a cm or two and the door still shuts normally.

Ill try them tomorrow, not botherd about the door card sticking out just as long as it shuts. Hopefully be ok
