i get alot of road noise when driving and im thinking of insulating the floor and the doors...
what methods should i use and where else should i insulate?
the roof?

i was gonna either spray with undercoating and then the silver sticky stuff that stops leaks

 

http://www.b-quiet.com They have lots of sound deadening materials at good prices. You can get enough to do 2 cars for like $55

 

thanks! but i cant order stuff, where i live it doesnt make sense where i live, i just want some do-it-yourself tips...
the stuff on that site does sound good though
im thinking of stuffing some foam in the doors

 

yea man, sound deadening is the way to go, but i suggest avvoiding the spray stuff, it cracks and starts to smelll from what i hear
but yea, dynamat, brownbread, b-quiet, you should be able to get them at most audio stores, count on teh smaller stores to carry the cheaper stuff, its all dynamat products, but just different, hence less popular names on it.
and when you ask for sound deadening, make sure you specify what you want, cuz if you just ask for it in general, theyre probably going to say dynamat, and not say what kind (brownbread, etc...) just to let yourself know what youre dealing with
i dont think its necessary to sound-proof your roof, the doors and floor and trunk panels should be fine, and if youre lookin to go hardcore, you get look for some for under the hood, but i think its different stuff from dynamat
hope this helps. good luck

 

yea man, respect

i want to find a way to deaden the sound from the fire wall in the engine bay...
ill check a couple people i know and see if they sell anything, i heard a friends set in a similar kind to mine and the entire car was shaking from the bass
i want to 'stiffen up' for my bass youknowhatimsayin

 

get under the rear seat of your honda(?) and apply it there. it's really easy to remove the rear seat on my 93 civic. just one bolt right behind the center seatbelt, and two hooks that keep the front of the rearseat cushion into the frame. it's the easiest one to do without removing the carpet. when i took mine off...the stuff under their was sticky. honda kinda put some noise dampening on there, but not much. here, i would use the sticky stuff you paint on, or the one-sided application where the other side is sticky.

the doors would go next. i'd apply the sound dampening that needs a heat gun to be applied. everything else would be tough unless your front seats and your carpet were removed.

 

cool, i dont mind removing the seats and carpet so ima go all out, you think thin strips of foam under the carpet would help?

 

since u cant order stuff try going to a hardware store and check out what they have in the roofing section and they might have peel and seal or somthing similar. use that everywhere you can. and then put a layer or 2 of carpet padding under the carpet.

 

great!
im gonna go to the roofing place itself
and im also gonna check some air conditioning places too...
carpet padding? can i ask for this by this name?

 

There you go. Use your imagination, after all most of it is the same stuff anyhow. Carpet underpad would make a huge difference in road noise. I saw a sample of roofing material recently that was exactly like Dyanamat extreme or brownbread. I bet the cost of materials is cheap. After all they make roads out of the same stuff almost and look how much they use.

 

if you dont like road noise, then no matter what....dont get yokohama tires. thats my advice.

 

cool...you think layers of putty will help, my floor is rotting and i was thinking of doin it at the same time...

 

ok, what brand would you recomend?

 

id recommend toyo proxes

 

That's funny, I found my Yok AVS ES 100's to be pretty damn quiet...I've heard louder that's for sure!!

 

Will carpet padding on the floor help with any noise at all??

 

i think so...

 

they make a yokohama AVS DB which is made to lower sound levels caused by the tires... and i would get dynamat.,.. i did it in my prelude and i noticed an improvement

 

Lexus advertised years ago about using ashphalt materials to reduce noise, guess what? It was just like Dynamat. Lexus had a hollow firewall filled with sand on some cars. A couple of stereo installers found out when drilling through it. haha.


Jimmy smoke crack, and I don't care.

 

bwahahahahahahahhahahahahahahahahahahahahaahhhahah hhahahaha

 

well, the avs100 tire from yokohama isnt as loud as the others. im running advan a032r's on my hatch and A520's on my coupe. they both sound almost like swampers. haha....id recommend the toyo proxes, or the falken zeix.

 

i think it would...but it might deteriorate faster than the dynamat-type stuff. i'm not sure how right i am, but i'm thinking the flatter the foam gets over time (from people stepping on it and stuff), the less space between the foam to keep the noise down. just cuz i don't wanna gut my car more than once or twice ever, i'd stick wth something i can forget about, like real sound dampening stuff that you heat-gun apply.

when i was working on this one car, the trunk lid had styrofoam under it. i was thinking, "yeah i can see why they did that." but then, on the surface of the foam, they had a long sheet of aluminum foil covering it. maybe they know something i don't!

oh yeah, although they ain't the highest performance tires, i got the old yokohama s306's on 3 tires, and the replacement for it, one yokohama yk420. there's road noise, but not that much, for me at least. i just turn up the bass and it's gone. i think with aftermarket wheels, there's almost always gonna be more road noise cuz the sidewall is thinner, and the contact patch is bigger. go 15's! hehe

 

No, Perelli P7000s are freaking LOUD! I cant even hear on my cellphone!!

 

ehhh - i just used 70 sq ft of brown bread - 1 dynamat door kit - & soem dynamat Xtreme on tha roof....

that did it for me.. no worriez about road noize now...

well i did it for tha SPL value.
