Should be no problem at all with fit.
Off topic but:
Not sure about the sound quality of the kenwoods though, but thats just me.
If you have stock front splits i.e. with the separate tweeter under the vent looking things on top of the dash, then you should fit better splits in the stock locations. The factory splits may sound better than the kenwoods if they are not splits also. However if your VT only came with coaxs in the front doors (like mine), then almost anything is a worth while upgrade. A nice set of splits is the most important part of an audio upgrade IMHO. Closely followed by sound deadening/sealing of the doors.
Have fun.
