I had to relocate the hood release on the Kia. It wasn't hard. I made an ABS bracket that bolted under the dash and the handle bolted to that.

Initial fitment of Owens Corning 703. One layer as thick as I can and keeping window clearance, full coverage. I taped in with foil tape after this shot in spots to hold it all in. Kinda looks like a smuggler's door.
A little work on the doors today. Finally sealing up...
Chipboard rough template..
.020 aluminum sheet..
For lack of the best tool for cutting, doing it in two pieces..
Covered in CLD on backside and attached..
CLD to hold..
CCF on for the smaller holes.. Gaffer's tape helps.
Also in the process identifying all holes that didn't serve some purpose for a push pin that needed to be covered getting covered with CLD. Door cards will get more absorption love as well since I only used 2 of 6 sheets of the OC703. Using 3 of 4 principles here with treatments: absorption for minimizing enclosure backwaves as much as possible, dampening, sound-proofing (CCF/MLV layer and sealing).

Driver door done. No sealing this any better if I tried I'd say. Very likely overkill but goal was see how far I could take these doors.
Keeping in mind backside is 100% coverage with CLD, so these little sheet metal panels should be somewhat inert pressed behind another CCF/MLV layer. Hopefully along with the absorption the back waves will be less damaging.

There's no such thing as overkill in a Honda
I can confirm this door work did some incredible things for coherence by minimizing backwaves back into cabin. Midbass region really tightened up as well. What's interesting is a massive weird phase shift and dip or rather cutout I had with the two playing together at 159hz completely disappeared. That's a testament I suppose for any scenario for the power of good treatment work. Found an EBU SQ Eval album somewhere and did confirm though the 100hz "gong" track will bring out the weaknesses.. pillars, panels, even the rear doors start buzzing. However there were a few signature tracks before that were brutal even at low volume.. Enough to make me finally address the install work.. Huge improvement. There's an actual bass track there now instead of "blap" and "bzzz" and just bloated I'll-defined mush. In short.. The work was worth it. Big time.
