Dynamat Behind Speakers

[sungwei 10+ year member]

I'm debating on whether or not to place dynamat behind my 6.5"s in the front door. Will it make that much of a difference? I have the dynamat lying in my garage, I'm just not that motivated to take my panels off again. I do get a bit of rattling in the doors on certain bass frequencies.

do it. i put sound deadener on my door panels and it made them sound ten times better. the bass especially sounds tons smoother.

Did you put it on your entire door panel or just behind the speaker? Problem with the Accord is that they have this white plastic film that covers everything so it's a bit ch to get to the metal door panel. What's behind the speaker is very little space.

damping th eentire door will yield the best results.

if you only have alittle bit of dynamat though do the panel that the speaker attches to first, then the rear skin if you have enough left over....

each door in those pics has 24 sq feet. an could probably eat up anopther 6 feet with no probem.

Oh yeah I saw those pics already. So you're the sound deadening psycho responsible for that! Seriously though that is a really nice job and I'd love to hear what your car sounds like. I don't want to do anything that extensive. I can't believe over 20 sq ft was used for just one door! That's nuts! I thought that was enough for a trunk. I have about 4 sq ft and I was gonna put about a foot behind each speaker and see if it makes a difference.

I just did my two front doors today and finished up my trunk lid. I put it inside the door on the rear skin and on the panel the midrange mounts too. And I am very well impressed with the sound difference. Not to mention that my trunk no longer rattles like a tin can. There is hardly any rattle at all out of my trunk.

What did you use and how much did you need?

What's rear skin?

What's rear skin?

I would also like to know what rear skin is. Is it the part of the inner door that touches the plastic panel? Also, how many layers on the panel and rear skin? I heard someone say 2 on the panel and 1 on the rear skin, but I can't remember.

Here's the door from my accord:

Close to 15 square feet of hushmat on and in the door.

i bought dynamat extreme door kit and i still had 1 sheet left after doing both of my doors. i did it before installing my speakers so i couldnt tell you the difference it made, but i did notice it reduced the road noise. and i know i didnt do such a good install.. i left the place where the door wire is open and a lot of other places uncovered.

Dude, that's sweet! I was considering doing that, but I just figured it was too labor intensive.

So you just ripped that white plastic right off? I was considering that, but was worried about it's function. I was concerned that maybe water and stuff would get inside the car, but I guess if you cover it up with sound deadener it doesn't matter.

By the way you said on and IN the door. What do you mean by in the door?

Some hushmat was also placed on the interior of the door panels and the outside door skin. Yeah the plastic was just removed.

there are 2 panels to every door. the inner skin and the door panel

THe skin is the same panels that is painted on its opposite, out side of the car, the door panel is the metal fram that the upholstery, door shell attaches to

check ou these pics of an old VW bug I dampened recently:

I went through a lot of detail in these doors. each one has about 24 sq feet of Second SKin

Hope that explains it
