This is what i have been working on while im waiting on my beta parts. Do you think this will keep the road noise???

 

just picture that Toyota commercial where they guy is in the car with a ferocious sleeping badgers and they shoot off a cannon and it doesn't wake the badger up up...

That should work pretty well.

 

In my old Accent, I added 4.5Kg of Polyguard... A spray on polyurethane coating with rubber flakes about 4mm thick just to my hatch. Thing is so heavy to get up and down but I gained 4DB from doing it. Another good stuff to use is DYNAPLATE or DYNAMAT.

You have to use sound absorbing material...not duct tape! tongue.gif



Just kidding...you should definitely hear a difference with all that. Are you doing it just for road noise, or for better stereo sound?

 

That looks expensive. I dont have the money to pull stuff like this.

 

It only cost me around 80 bucks for the stuff. I thought it would be more but it wasnt.
I got it from here <--------

 

i have edead and upholstery grade foam in my car..
it's very quiet when i'm in the car..i can't hear wind or other nearby sounds..
it definitely helps the bass and roada noise, add some on the hood and it'll be quiet as a lexus..unless you have a intake

it also helps dampen the sounds of road debree being kicked up on your fenderwells, like pebble's and sticks.

 

Where did you install the foam at?

 

the quarter panel cavities, i took off the plastic panel and stuffed it like crazy, helped the NVH alot..
