Sure, You'll have to cut the metal though...

cut the metal with what?

I put 6x9's in the front and rear doors of my 99 f150 ext. cab. I used a dremel tool with a cut off wheel.

awesome awesome awesome, now- 3 or 4 ways?

2 ways

Yup, cutoff wheels(fiberglass reinforced kind) work well! , have used an airsaw before, but messier and louder.

I vote for the 2 ways, they seem to generally be more crisp at higher volumes. The others all start to sound like a badly recorded MP3.
