Stock Stereo Setups, Trying to figure things out Options

[Fastbird]

Ok, after searching and not coming up with anything clear cut:

What are the factory soundsystem setups, I.E. head unit combinations, speaker setups, amps??, speaker sizes, ect.

I'm mainly trying to figure out what exactly I have in my 99 GT so I can rip them out and throw in better things. I plan to stick with the stock size and throw a sub in the back (probably a single 12, not sure yet).

I have what looks to be component speakers in the front doors, but I haven't taken a close look at the rear side speakers yet.

Can I get some guidance please?? Usually crutchfield is pretty good about showing what's in there, but it blew chunks this time.

Cool.  So do you have any more questions?

Actually yes, now that I KNOW that I have the 6 speaker system:

What exactly are the speaker sizes I have and what aftermarket sizes fit??

I think I have the following:

1" Tweeter in door behind mirror
6 3/4" Woofer in door
6 3/4" Woofer in rear side panels.

And I assume that the same sizes fit fine with the aftermarket stuff (plan on going components in the front doors, coaxials in the side panels, and a 12" sub in the back).

FYI I haven't made up my mind if I want to go with Alpine for the speakers or splurge on the Infinity Kappa stuff yet. I have an all Infinity Kappa setup in one of my Trans Am's, but I don't know if I can justify spending that on the Celi.
