Road noise is a very large part of the noise you hear when driving any car. The doors are responsible for a large part of this, so if you want to quieten the cabin, the doors are essential.

Put it on the back of a low loader……
Oh dear. How bad?

Okay weirdo lol, how long did this take you? And just from an engine start-up immediate impression, what kind of sound difference are you noticing inside? By any chance did you weigh one of those Hybrid 3-1 mats to see how much they weigh?
I pulled out of the garage without remembering the batter tender was plugged in. Only the CTEK quick connector was damaged as the wires were pulled from the terminal, but I'm not sure I can repair it.
Makes me wish I had gone with this: https://hethelsport.com/tools/charger-connection-kit/
That’s what I use. Saved me a few times already lol
I took less time than I had imagined. Started hmm..1-2pm Saturday, busy Sunday, Monday after work was basically done when wife wanted to do a Costco run.
In total, If I was prepared with everything I needed it's maybe 4-5 hours to get in there cut stuff to size and put it back together. It's pretty tight space to work in though. I didn't take a seat fully out but it would be smartest to do that to both seats.
I get pretty easily distracted though, started really looking at how these cars are put together, looked at the speaker mounts, etc. Plus dropping screws down into unreachable pockets adds time.
I've only done the back firewall and a little into easy spots on the qtr panels. I'm thinking I should do *something* in the doors. Probably just a strip or two to knock down some high frequency, not skin the whole door.
I'll put the seat back and fire up the engine to get an initial impression though.
Goal is to add less than 10lbs of material.
Would love to see that !
Not sure if you've seen this picture of the guys who did a sound system upgrade in the UK. They also did a meticulous soundproofing job on the doors resembling a jigsaw puzzle. The picture could help in planing for your project, if you choose to go ahead with it. Looks painful, but I may take a shot at it myself sometime in the near future.
I didn't drop the cotter pin, but dropped the OEM eyelet 
. Will need to retrieve at the next oil change.
Shift feels nice and short, but not as stiff as expected (which was a pleasant surprise).
Bespoke template for shifter position adjustment.

I've seen a few of those photos floating around.
Gotta be honest. I'm not sure that's the best way to accomplish what needs to be done.
I would think actually that the best application would be on the outermost door skin, effectively between the door and the pocket the glass will drop into. It's also going to be the smoothest part to apply material to because it can't have any brackets or protrusions as they'd interfere with the glass.
All that said though.
On the drive after button everything back up. Result. It doesn't pass the "would my wife notice" test.
It might lower the sound floor, and on a real long drive may result in a less fatiguing experience. However, it's not noticable by anything more than a placebo effect.
I will have to drive back-to-back with another car to be sure, but the bulk of the noise is just background super charger whine, and that's not going anywhere. I suspect mostly coming through the glass.

Are you mostly trying to reduce road noise?
Just generally make it a slightly less noisy place to be.
Some of that will be reduction in road noise, some in mechanical noise (gear whine, valve train, chain mesh, etc).
Still to solve (and may not be present in passenger seat) wind noise when going roughly 70mph+
Wind is coming from right behind my head so I need to look at the window seals and what can be done.
Installed mine on day one, love that they’re softly backlit.
When I changed the oils (both engine and trans) and put Archoil 9100 in them, which is a friction modifier, the mechanical noise was noticeably reduced. For the engine I put Pennzoil Ultra Platinum 0W-40 (not the Euro spec which is for people who only change their oil every 10,000+ miles), and for the trans I used Red Line MTL 75W80 GL-4 Gear Oil. I used a Purolator Boss oil filter for the engine. I changed the engine oil myself, but had the dealer do the trans oil change.
Jay Leno's mechanic swears by Archoil 9100 and uses it in Jay's billion dollar collection of cars. You use 1.2 oz per quart of oil for both the engine and trans. You have to remove that much oil, and replace that amount with Archoil.
Get some Honda Shin Etsu grease (you can get it at the parts dept. of a Honda dealer) and use that on the door seals, both the door itself and the door frame seal. No more squeaking or wind noise. Get some Nitrile gloves, put a dab of grease on your fingertip, and start working it into the seals in sections. A tube of grease is small, and you don't think that's going to do the job but it does; a little goes a long way. I also put some on the trunk seal.
Wind noise if the window is rolled down, is coming from the seat belt above your shoulder. It chatters in the wind. I haven't figured out the solution for that one yet.
I've been wanting to address the tire/road noise, and I was going to do what you did with the firewall, but I guess that's not going to help. Thank you for taking one for the team and finding that out. The only thing I can think of for road noise, would be putting sound deadening material on the backs of the wheel well liners, but those are made of a fuzzy kind of material and I don't think a sound mat would stick to the back of them. Maybe in the Spring when it isn't too hot or cold, I can get the car up on the Quickjack and see what can be done.
Drove a total of ~2.5 hours in a consistent rain last night. Car was parked in the rain for a few hours mid-way. I don't have the new AC resistor rubber sheet installed and my AC still works perfectly (have also washed the car more than a few times). Very interesting to see that it's not a guaranteed failure mode. 2,000 miles on the car.
It was also 42-44 degrees F and I'm on Sport+Goodyears, so it was a good trial run to see how the grip was at relatively low temps. In short, very confident. No fooling around, obviously, and in Tour the whole time, but I did downshift and hit ~ 50% throttle to pass a few times on a two-lane road with no grip issues. Plenty of twisty backroads at 55mph and interstate turns at 75-80mph, all felt very confident while driving with 100% focus and smooth inputs.
While I think I'll eventually get winter tires/wheels, this was a pleasant surprise. Any colder out and there's likely to be salt when it's wet, so this was really the extreme case for how I'll use the Goodyears.

I am still debating... I am sure this is a bigger undertaking than I want to deal with.
