What's the best way to soundproof a 2001 honda civic?

I'm trying to figure out the best way to soundproof (or just quiet) the road noise in my 2001 Honda Civic 2/door. It's kinda loud at 70mph. All answers that are legit are appreciated, especially those from others who've done it already. ...Undercoating, additional carpet, new carpet pad, etc, etc???????

Thanks

Take out all the carpeting, and paneling and Dynamat it. Dynamat is mainly to keep your car from rattling due to the power of a system. But the reverse effect is also good it will keep sound out. This will provide a nice smooth, and queit ride perhaps some Bach to enhance the experience.What's the best way to soundproof a 2001 honda civic?
Use Whispermat 1/4" or 1/2" material. This material helps to not only control sound transmissions, it decouples the structural vibration by separating the mass of the vinyl sound barrier from the structure it is being attached to. http://www.acousticalsolutions.com/590~alphacomposite-foams

What's the best way to soundproof a 2001 honda civic?the way i did mine was

Start by ripping out the entire interior. Im talkin seats, carpet, plastic door panels, the dash, the whole works.



Next clean it REALLY REALLY good with a biodegradable, non residual degreaser/cleaner. let it dry.



Buy 4 bulk packs of Dynamat xtreme, 3 cases of dynaliner, and 5 gallons of Edead in whatever color you prefer.



Start by applying the Edead with a thick paint brush to the roof of the car, and work your way to the floor, and dont forget the inside of your door skins, and the outside. Repeat until its gone. All 5 gallons.



Next lay out your dynaplate on the floor of the car and cut it to fit.



Lastly get a couple fresh razors and one of the heavy duty rollers that dynamic control sells, and go to town on every panel possible.



Get out your fresh jute, new carpet, lay it down and start piecing it back together.



WALA! you have one of the quietest honda civics in the world.What's the best way to soundproof a 2001 honda civic?
don't take offense to my answer, but its not a cadillac or a BMW.

my cars makes alot of road noise at those speeds also. i would think expensive cars dont make that noise. and nothing will help with that noise, maybe just lower the window a little bit so the air drowns the noise or turn up some music or just let it be or enjoy the sound of your car going fast.What's the best way to soundproof a 2001 honda civic?use dynamat(xtreme version only), and use it on your doors and also trunk, this will take away a lot of noice, it is a sound damper, and can increase music volume loudness, and give you a quiet ride, about 3 bulk packs should be more than enough, dont forget to use the tool to apply it right, I used it and my car is quiet even with two 12" subs in the trunk.What's the best way to soundproof a 2001 honda civic?
There are few step.



(1) extra padding under the carpet

(2) sound deadening patch inside the door panels

(3) sound deadening material (replacement) headliners.



They do this at specialized location in NYC (bad roads here).





Good Luck...
do what MM said with the sound deadener also look into different tires. Some tires create more road noise then others
