I think you've got a good handle on this, looking forward to seeing progress. You should post up on https://www.diymobileaudio.com/ if you are going to do a build log on it. Can get some good fab advice over there too. (if you aren't already on there)

Corner sub
Gladen amp behind passenger, top down just clears
twiddler
Gladen 3 way system with active filter
Butylen insulation sticky inside door
+ cable to amp
Ensolite insulation passenger side
Maybe this can give some ideas, I just rebuilt my convertible with all new stereo and ripped the Bose out, it is very tight where the roof is coming down but i did get the Gladen 4channel amp bolted to the floor on a glued wooden 1/2 inch board it just clears the roof.
I did buy the Vettenuts cornersub 10” JL and put that one in the passenger side box in the back.
The door speakers i did replace with a 3 way kit Gladen 6.5 / 3.5 in the doors and the twiddler is placed in the door handles i did a cut out there, surely you have seen others do it also.
Did replace the back speakers 5.25 with Fosgates they droppes right in but maybe not so good as they tends to bail out so i fade sound forward so they are more of a fill out so to speak.
HU is switched to a doubledin Kenwood with DD panel from Vettenuts, new USB port in the arm rest to connect with stereo.
Whole car have been sound insulated including the doors, it is a good upgrade campared to Bose system and makes the car more modern.

installation of Vettenuts DD, cut out both brackets.
almost finished, looks like stock the panel and very good fit, 7” had to cut a little bit in it to clear the ooeration of door to stereo
Wow that’s great! Thanks for the pictures. And it’s even a MY convertible! Good taste 😁. I just built a mock-up vertical amp rack to go behind the waterfall. It’s very tight. I’m now looking at shaving 1/8” here and there to get clearance with the folded convert top. The jury is still out if this will be feasible. It definitely would not work with any amp larger than these JL Audio Vxi amps! I see you have the vettenuts corner sub, how is the bass when the top is down?
I did change all cables also there is place under door - floor, there is a small hatch to get acces to cables through door but be careful to place and hang cables out of the window mechanism if you do this, i trashed one of my filters thanks to sloppy install.
MY convert is the way to go 👍

Well I’m now in the middle of the install and just discovering that wiring for Retained Accessory Power (RAP) will not be possible! The Accessory Valet by Top Down Tech is no longer available 
Has anyone ever figured out a way to wire it without using an accessory valet? I have a Window Valet but when using an aftermarket HU it will not control the RAP function as I understand. Is this correct?

Still sitting in the box!!!! I just started the install last week. Only had a few hours to work on it this week and keep having to order stuff online and wait for it to come in! Installed the Big "4", completely disconnected every ground, cleaned and reset, cleaned every electrical connector in the engine & interior compartment, changed the hazard switch and installed the hyper flash module, remove and cleaned the ignition switch, replaced the existing top mounted battery cables (2004 only) to side post cables and installed a Yellow Top dual post battery so the top post could be used for audio and Big "4" only. I also gutted the entire interior including the dash and instrument panel. Installing all LED interior lights even in the IP and also installed brushed aluminum gage bezels. They look sweet! Laid out the cable runs, installed backup camera and installed two 1/0 cable bulkhead watertight grommets because I'm running the negative back to the amps also in addition to grounding the amp rack to the left rear B pillar. Getting ready to do wiring harness and then start on full sound deadening interior. I will post a write up towards the end when i get time with pictures.

Well, here is a quick update and teaser photo! My baby has been down since September with this audio install! I completely missed the entire foliage season in New England and the local Corvette Show which I won last year. It is taking a lot more time than I anticipated but since I’m a perfectionist I can not rush it just to hear what it sounds like! I finally reassembled the car and all the wiring is complete. I now have to finish the skeleton of the amp rack before I can complete the connections to the amp and fire it up! I also need to finish the beauty panel to finish off the amp rack and fiberglass the tweeters in the A-Pillars. Unfortunately we got 6” of snow today and it’s now freezing out which doesn’t make for the best conditions in my garage for woodworking, fiberglassing etc... so I may or may not even be able to hear the fruits of my labor until the spring. ☹️ I will post a complete log post of my build with pictures when finished next spring! If I get a chance to hear some early results I’ll update you.

Bro! You can't give us awesome teaser pictures with Focal Flax's and an amazing install only to leave us hanging. Finish comments or ban!

Are you not going to run a small tweeter? Or are you just running the 3.5"s? 3 way set or 2 way? Tweeter pods on the pillar? That's what I'm doing to mine...
(EDIT: I'm really anxious to hear your feedback about the VXi in particular. How well they work together. How easy is the internal DSP? Etc. etc)

Are they focal? Reason I ask is Focal has GREAT off axis response, so pointing them directly at your nugget isn't absolutely crucial. However, if pointed at your nugget, they will sound that much better. Biggest issue I seem to have in mine is mid-bass. When those tweets are screaming, it's easy to lose the balanced sound.

All true...however, you're using a DSP. All that makes everything else irrelevant because you're able to tune for orientation and placement.

Yes I did live concert sound for years. While we didn't use "rear" speakers we did use fill speakers.
Sometimes located about half way back of the venue. These filled in the holes and cut back on echo.
While echo won't be an issue in a car it will fill in some holes.
Again just my .02 worth.
