Well, not to offend, but don't be surprised if that sounds terrible. I mean, it will sound terrible. No doubt. And if you run a full signal at those tweeters from the headunit, they aren't going to last long. And why on earth would you want 4 tweeters AND coaxials? Do you have any idea how much signal cancellation there is going to be in that cabin?
I don't care how you install it, that's a recipe for disaster.
The best advice I can give you is to ditch the 4 tweeter idea and just invest in some proper comps worthy of the substage. You can go active if that's what you want, but buy the proper gear, i.e. a crossover or amp/head unit with crossover capability (if you don't already have one). There is absolutly NO reason to have more than two tweeters in a car (barring rearfill use, which many will recommend against). Even two, with relatively low wattage, can be ear-piercing. Adding more tweeters is not going to make up for poor planning or poor tweeters.
As for midbass, it's going to be difficult to find anything that can run with those subs that'll fit in a door. That's just reality when you have that much power on such a brutal sub, you can pretty much forget about any illusion of "up-front bass," unless you're willing to do a hell of a lot of work up front, like putting 8s in the doors hiding a sub in the center console or something to that effect.
Really, what you need are some decent components. Perhaps Crystal SSCS 6.5s would do the job well enough. They won't break the bank and they're good. The metal dome tweets will cut through the bass and at that price, those mids are the closest thing out there that have a chance at running with those subs.
Save yourself the money of having to upgrade down the road and save yourself the aggravation of ending up with something that sounds awful.
Hope that helps.
Edit: I was typing this long-winded post while the thread carried on, I'll leave this stuff as food for thought, and my recommendation still stands. So, there it is.
