Have anyone tried sound proofing their cars? I bought some sound absorbing foam, sound reflecting vinyl, and sound damping vinyl for my car. I put them under the front carpets (absorb + reflect) , inside the front doors (damping + absorb) , over the rear shocks/wheel well (absorb + reflect) , and my tailgate (all 3) (the inside of the tailgate was comptelely empty... made me wonder if I bought a Kia instead of a volvo). The results were pretty good, the exhaust noise was greatly reduced, also road noise is a bit lower, the wind doesn't seem to seep though the door much now... and I guess since the car is much quieter overall, I'm beginning to hear the transmission whine a bit more now. It is much quieter at higher speeds than before now, I almost don't need to turn the radio up at all no matter what speed I'm at. And I can floor it and not to be overwhelmed by the engine/exhaust (some of you won't like this! <P>Wanna hear from you all if you've done anything like this and the results

it is very time consuming, took me 2 days to finish the whole car. Got alot faster near the end of course <IMG SRC="http://www.swedespeed.com/ubb/smile.gif"><P>the hardest part is to open up the tailgate trim, damn near impossible, broke 3 out of 4 plastic clips that holds the trim together...

The sound proofing on the tailgate trim will help stop the dreaded rattles, and yes, everyone breaks the clips; the only solution is a trip to your dealer for new ones.

my tailgate didn't rattle but now I almost can't hear the exhaust coming from the back... maybe because now the front is so much louder (in coparison) <IMG SRC="http://www.swedespeed.com/ubb/smile.gif"><P>its wayy nicer at higher speeds now tho, going over 130km/h (75mph) doesn't seem so bad anymore.
