My after market audio guy claims that the woofers are 8", but only a very few replacement speakers are shallow enough to fit the doors.
I'll find out more next week as we will be in the doors playing with a crossover circuit. The stock speakers sound great when we applied Dynamat in the doors, better use of money in my opinion then replacing the actual drivers.
I agree with Lash LaRue, I am pretty adept at the Google thing and I have found virtually no information on the topic. So I will try and contribute in a few weeks...
