Our plan is to put 2 6.5 components and an 8" sub into the center console, which has yet to be fabbed. The dash speakers are coming out.
I need to leave the doors 6x9, since I have no further interest in making a patch for that. I need a certain level of loud to get over my obnoxious exhaust noise

The 66's don't have nearly as many openings in the door, so I only have to cover a fairly small area under the door card it looks like.
What about the polyfill stuff, does it help anything or not really?
