OK, so I know it's not a big issue, but...

 

Since I got my Legacy (originally intended to be an engine donor, but too nice to part out) and began driving it, I notice it's a lot quieter on the road. It seems like the GLs are especially noisier in transmitting road noise from the rear wheels. Has anyone used any kind of sound deadening material, and with what kind of success? Thanks.

I did notice that the carpet in the bag of the Legacy I was checking out at

the JY was thicker than in my GL. I used a bunch of soft foam bricks I scored

at my work and stuffed all the holes in the back. Like where the jack goes and

the little hatch under the carpet and wherever else I could stuff it. It helped,

but I'm still thinking about putting something under the carpet. This stuff

would be great, but it's not cheap.

And then there's the old stand by carpet padding

well in sound audio meets we would just pour in a few pounds of concrete in to the car.. probbaly wont work for your application but it sure kills sympathetic resanace (sp)

I had a VW Fox, filled a bunch of cavities with the expandable foam, and it helped considerably.

car sterio noise deadning materials worked wonders for me, eg. dynamat. goes any where in the car you want it quite.

Yeah you got to go Dynamat. The stuff works great. Well worth the price too.

You get what you pay for with sound deadening. On the other hand when you go to apply it most caraudio guy will use at least two layers. That will cost you at least $200 with Dynamat. This is what I use http://www.fatmat.com/fatmat/bulk/100ft.htm It comes out to like 125 shipped.

Hey,

I thought it was just me and my old soob with the noise. Thought I had an error and repacked rear berrings with hight temp synthetic (I mean REALLY packed it). Now I've got a poor man's cadillac

heheh, i undercoat for a living 2-3 coats of that will make even a dump truck quieter
