biggest speaker possible in rear speaker holes

[Soma576@xxxx]

List,

i am interested in getting rid of those terrible 4x10's and putting something 
half-decent back there. what is the biggest possible speaker that will fit 
in the hole w/o modifying the trim that goes over it? i don't mind making a 
plate or brackets.

4" round? 5.25"? 5x7? 6x9? 6" round?
