When i turn my system on i get some really bad rattles in the doors and hatch, what kind of sound deadener would work best, i know about dynomat but its quite expensive, i was hoping for something that came in a spray can....or would just like a rubberized undercoating do the trick. Any imput would be appreciated.

You can buy spray DynoMat for the doors.

Regular undercoating will work..just be careful because it goes on thick. Also, as far as the hatch goes...you're better off using sheets of sound deadener than the spray. The spray is good for the inside part of that hatch, but if you want to do the actual hatch (rear window) itself, than go with sheets. You don't have to use Dynomat for that. If you go to any major search engine and type in sound deadening, you'll come up with a ton of little shops that sell no name stuff that works just as well as the name brand. <img src=icon_smile_wink.gif border=0 align=middle>

I've used the expandable spray in foam/ insulation in my excel. No rattling anywhere from my stereo. I didn't put it in the doors and don't recommend it for them! Can get it at home depot or lowes it's about $3.79 a can and I used around 10 or so cans.

WOW..I heard of my 4x4 friends using that expanding foam for filling their rust holes in the trucks, but never for sound deadening! Good show! <img src=/images/forums/snitz/thumbup.gif width=25 height=18 border=0>

Personally spary foam is the worst thing that you could possibly use, thats just because if you put too much in it will flex your panels, Dynomat is expensive but its pretty effective, but look for a product called V-Block its the best out right now.

Definately do not use spray foam (expandable foam). TypeR is right you could push your pannels out if you use too much. It is also hard to determine what is enough cause it will keep expnding while it dries.
