  1. Hi, I finally got up on the noise in the Legacy, bougth a MB CLK and now it is quiet. I mounted bitumen mats and noise dampening mats in the whole Legacy, and yes - it sound less, but the factor that generated the most sound - road noise - was never ever effected by the sound deadening methods. From my perspective, it is not worth either the time or the money spent! Greetings from a happy CLK owner //Peter
  2. So, after almost half a year, I have sound deadening almost the whole car. The doors are fixed, with all possible stuffs. I have also removed all the interior in the back (have a wagon). Extra materials all over the car, I guess it's at least 30 kg in deadening materials. Yes, It has been better all the time, but after driving my old BMW and Mercedes = STILL A DISASTER. I think the main reason for the extreme sound level is the horrible roads here in Sweden. Couarse roads, you havent seen it at all. The first trip make me almost cryed.. What the heck have I bought, my first personal payed new car!! My wife in her new BMW 320d had an very pleasant time... So I started to deadening the doors, the wagon parts etc. At least 500$ payed in different stuffs. Also hired a sound meter. Data of the car is 18" wheels with Goodyear Excellence tires. First, I got Yokohama Avance or something likely named. Sounds horrible. They replaced it with mentioned tires. Sounds as hell, still. I think I have reduced the sound level with at least 2-3 db, but I am embarriced to take a customer for a long trip.. So, finally I find my solution: Change wheel (the original 17" tires with Yokohama SG2 winter tires) Even if this tire is the bottom 2 of 10-12 winter tires tested, at least the $£€@@ fcn car it QUITE now. Conclusion: 1. If the roads are bad or like in a war condition (like here in the great country of Sweden) you cant sound deadening the road noise. 2. But if you take the time to do it anyway, you can make it a whole lot better 3. But (hate to say it) if you go for smaller wheels, and higher tires its gets a lot better. Just let us be comfortable with that the Japanese manufactures with medium size (size $$$) cant make cars with a low sound level droven on couarse roads (not to mention Lexus etc) 4. Change to that booring wheels you dont like, and it sounds....nothing, even less it you really have completed the point2 above. ps 1. Will never forget the horrible, terrible trip in Stockholm in June, it was our 10th weddingday, new car and my military service was a less hearing experience. ps 2. all respect to Toyota who made a "swedish" road in Japan, just to eliminate the sound waves going throut the chassis. ps 3. Pray to whatever you like, it you think your car is quite, it is because your roads are perfect.... Dont think you live here in Sweden.
  3. Hi Using bitumen (asphalts) mats and isolation I fixed all four doors for less than 150 $. Used bitumen mats, 3 mm and 1,5 mm thick. Then I used isolation mats in 10 mm or 30 mm size. For bitumen mats ---------------------------- 200*250*1,5 mm is around 1 $ 400 * 400 * 3 mm is around 5 $ For isolation --------------------- 1000 * 500 * 30 mm is around 12$ The result is fantastic, it feels better than my old BMW and Mercedes and the result is great in terms of sound isolation. The overall sound level in the car is reduced a lot, the doors feels thight and feels like "quality'". Only on coarse roads, you can still heare some noice, but I thing that is related to the isolation in the chassis. As a great bonus, the stereo sounds a lot better ! There are a lot of space in the door sides, fill it up with isolation, up to the level of the fasterners, and a little bit more. The tighter the better in terms of rattles etc. //Peter
