Worth completely sound dampening my accord? (CLD, CCF, and MLV)

[ladysmanfelpz 10+ year member]

I've been talking to Rich Aka (Keep hope alive) and picked up all the materials. I did the entire rear deck and doors so far with great results. I still have 30 sq ft of CLD and a roll of MLV and the ccf. Its a coupe and shouldn't be too difficult, but I do question my skills on putting this thing back together. So does sound dampening the entire floor make that much of a difference?

I can tell you the majority of my noise sources are my rear wheel wells for road noise, and mirrors and such for wind noise. My main concern is does sound dampening an economy vehicle ever match the road noise of a luxury car? If not I don't think I'll spend the time and effort in doing it and wait til my next ride for a better sound system.

Thoughts appreciated. Thanks everyone.

It will help. Mostly the MLV. You can never stop wind noise from the Windows.

It wont match it but it'll get a big improvement. Lets just say a 1990 civic can sound like a 2016 civic in terms of road noise.

That's the main reason I picked my car. Of all the mid size sedans in that class it was by far the quietest.

Yeah honestly next car I'm looking at the road noise as main buying factor. This car ain't bad, but its small so you get significant road noise even tho its well built and has a quiet engine. It's something I've always wanted to do, but after seeing a shop rip apart my rear deck and put it back together in a breeze where it took me a whole day made me rethink my priorities. I'm 25 and still looking for a career and have lil experience with car audio, so it feels like it is all time wasted. If I was in the game or had past experience with installs I would take this hobby much further, but it looks like I've already missed that window.

And now after listening to the new speakers, I am getting more rattling from my rear deck (6x9's) and know I would have to go to significant lengths to make me happy. I may be moving on to old man stage of just buying a decently quiet used luxury car and simply throwing in an MS-8 and calling it good.

Sorry for whining fellas. I'm moving and going through a job change so a little stressed out. I do really wish I gained some experience in installing as it is not the hard work that bothers me, just my lack of experience in the field even tho I enjoy the hobby immensely. Too bad that job at best buy as an installer didn't pan out //content.invisioncic.com/y282845/emoticons/mad.gif.c18f003ab0ef8a0d9c27ca78d77a6392.gif

Thinking more about it I have made the decision to not fully sound deaden my ride even though I have all the materials. I am moving in the next 10 days and can't waste 2 of them tinkering with my car when I need it for a 1200 mile trek. It's not the whole taking it apart thing anymore, but I know once apart it will be a bigger project than I expected. Plus I am mainly interested in getting the little creaks and groans out of an aged car, and know that will never be fixed except by purchasing a newer vehicle. Also the wind noise and road noise of other vehicles is the main contributor to my cabin noise, so don't think I would see spectacular results from a deadened floor.

After my 6x9 install I am getting some farting in my rear deck most likely due to greater output. I have the aluminum shelf near 100% covered on both bottom and top with some small vents left open due to air flow purposes. The deck lid is covered with CCF. Is there anything else I can do? Like I said I do have more CCF and MLV, but I think MLV will just contribute to rattling. Ideas are appreciated. I may go through the effort of disassembling this to further deaden and may as well get my rear seat area and rear tire wells as they are big contributors of noise.
