What I'm really asking here, is what are your goals?
Just an assload of noise from many speakers?
You will in all reality get much better results from eliminating some of those speakers. Think a simple system to start.
If you can get some good tweeters to match your mids, then running those in the doors would do well. Toss the tens in the back and amp everything.
Trying to run different sized subwoofers doesn't generally produce great results. Also running speakers in random various locations also doesn't really give you great results.
If you want it to look awesome and don't care about the sound, then triple up on all your speakers and fiberglass them all over the place (roof, floor, doors, steering wheel, etc).
