Audio in Integra GS-R

I just bought a 99 Integra GS-R and i was wondering what kind of speakers it has and what size they are. I know that the rear ones are Boston Acoustic and they're fairly small, but does anyone know the sizes of the front and back speakers??

Thanks a ton!!

I kno the fronts are 5.25

thanks!
i thought the back speakers would be 6x9's and lord knows they sound like it, but i was surprised to see how small they actually were.

The back speakers are 6.5 inches. I have a 1998 GSR and I have replaced the speakers in my car and 6.5 fit in the rear. The fronts I put 6.5 component speakers in, but I did have to use longer screws and screw into the plastic fitting where 5 1/4 usually go.
