Removing seat and floor liner to add floor sound deadening

[Finpro807]

I have a 2023 Integra Aspec (non-tech). I'm thinking about stripping my interior down so I can apply sound deadening material (Dynamat, Sound Skins, etc.) to the metal floor. It's just been too much road noise and NVH especially at highway speed or going through broken pavement. I was doing some research and people said the Integra didn't really have any sound insulation on the floor from the factory, and that adding floor insulation could seriously reduce road noise and NVH... Does anybody know if that's true? I went to a stero store and the guy quoted me $1600 for parts and labor (they used SoundSkin). It's a bit steep for me so I'm thinking maybe buy the material online and DIY.

Has anybody done project like this and can give me some input on your approach? Anybody knows how to remove seats (front and back), floor liner, and anything else I might've missed so I can access the metal floor frame? Is this a DIY friendly project or more of a pro only project? I'd classify myself as a handy person but nowhere near mechanic level. I'm also concerned about putting everything back correctly so I don't add more squeak and creak that Inetgra is already prone to.

Any input would be greatly appreciated, thanks!

Got a better idea.
Just turn the music level up and save the money.

Thanks a lot! Such a great thread to read it's almost addicting. Definitely motivated me to start this project myself, just need to know how to remove the back seat first.

Good luck. I think the backseat is pretty straightforward, should be the same as the Civic.

Back seat is very easy. Removing bottom portion only has a single bolt that needs to be removed, driver side above the cushion. Then 2 plastic clips under the seat that you push the seat down then squeeze clip and lift.

Thank you! Would I need to remove the backrest portion too to have full access to the floor?
