My brother-in-law used foam mattress padding from Wal-Mart in his Mini. It's an 06 Mini Cooper S that's been more than slightly modded, and used to be quite noisy inside. The mattress padding fixed the problem and only about 20 lbs to his ride. It's also fire retardant, and I think he spent about $40 in all. Definately going to go the same route.

 

ear muffs work lol

 

not too bad, wish the guy had done a before and after sound clip so we could actually see the difference.

Hell yeah that is practical! I say do it!

 

I took apart the rear interior of my xD, behind the rear seats, and stuffed that pink attic insulation every where. It made a big difference. I had done that earlier on my 05 xB. I think I'll try those carpet squares in the doors.

If you go to http://www.mcmaster.com/ and search for 'sound control' they might have what you are looking for. I'm at work so couldn't search in depth, but it looked like it might be there somewhere.

 

Hi pyroman;
You can buy "Pink" insulation in almost any home repair store, Home Depot, Lowe's, etc. It comes in rolls that are about two feet in diameter. It is fiberglass and it unrolls and fluffs up to about 9 inches thick and it fits between the rafters in the attic, except when I am stuffing into spaces in my car for sound absorption.

Its 2inches thick... Thats the depth.... Might be too fat for most applications.... you really need something around 1/4 of an inch...

I actually think the peel and stick carpet in the first post would be a good idea... It sticks, can be trimmed easily, and is probably not too thick...

 

BAck in the mid to late 90's I had a vw bug with 12 jl audio 10's in ported enclosures doing 154 db and we used undercoating - inexpensive and works great

 

I once used peel & stick vinyl floor tiles from Home Depot, 12"x12" for 59 cents each. Seemed to work almost as well as Dynamat, but was a lot cheaper. I've also used regular cloth-backed vinyl that you can find for cheap in fabric stores, it works well but you have to buy a can of contact cement (like 3M's Super77) to make it stick. You could also try spray-on bedliner, which isn't very cheap, but works well and is easy to apply. I'd stay away from undercoating, tried that years ago and it was more of a mess than it's worth, never really dries completely in spite of what the can states.

 

I just turn the music up,problem solved.

 

This is awesome!

 

pyroman volunteered to get the peel and stick floor tiles and do a DIY thread with a before and after sound clip! lol. i like to volunteer people without asking them first! haha
