SV6 audio upgrade questions

[adam sv6]

Hi all, i am new to this forum so please dont be too harsh on me!

I am thinking of putting a full Alpine Type R system with one 12 inch sub in the boot, but have a few questions for all the audio freaks out there.
Heres my plan:

In the front doors: SPR-50C 5 1/4" Component 2-Way Speaker (with the tweeter components in the dash)

Rear doors: SPR-50 5-1/4" Coaxial 2-Way Speaker

Boot: SWR-1243D 12" Subwoofer

Ok, it seems to me that the speakers are 5 1/4" but will 6.5" fit onto the existing mounts? If so i'll opt for the larger 6.5" speaker.

And Will the tweeters be a dog to fit or is it a matter of screwing them into a the same position where the original dash tweeters are?

Anyway what do you all recon of the speaker setup?
