I've already replaced my head unit with a Pioneer Avic-Z140BH. It's been great but I now have the Bose Sub cutout problem and a blown door speaker so it's time to replace everything. I plan on using Fatmat on the entire enterior and trunk. Here is the list of Components I plan on using...

Alpine SWR-823D 8" Free-Air Subwoofer
Alpine MRX-M55 Mono Amplifier
Alpine MRX-F65 4-Channel Amplifier
Alpine SPR-60C 6.5" Components for the doors

I'm hoping I can fab some MDF rings and fit those 6.5" in the rear doors. Does anyone have experience with this?

I will also probably leave the rear tweeters out unless I end up with too much low end. In that case I'd find a place to mount them somewhere.

Thought/Ideas/Suggestions? Anyone used any of these components and can offer a review? Thanks!
