Stock Speaker sizes?
Well, i've only been in my car a few times since i bought it(last week) and i work 5-6 days a week while going to school 5 days a week so i haven't had a change to crack open the speakers and see what lurks beneath! 
The front speakers are basically blown.

Re: Stock Speaker sizes?
4th gen would be 6.5" w/ or w/o Bose system. Bare in mind that the Bose system has seperate amplifiers for each speaker built in to the enclosure so keep that in mind when replacing. I had to redo the entire system in my 96 Z28. The Bose system was wired wrong from the factory... rear sub was on the rear mid channel and the mids were on the sub channel.
I replaced it all from the head unit back.
