Critique my deadening please

[stangman67 10+ year member]

Ok this is my first attempt at completely deadening/sealing off my doors. I have done minor stuff in the past but this time I want it to be great. I deadened the inside panel of the door as well as the outside panel. The inside panel was tough to get to but I would say at least 1/2 of it is covered. My only problem is trying to figure out how to seal off the one hole where my door rods go through to the mechanism itself. Not completely done yet just seeking some pointers on what I can do better/differently. Thanks

Here are the pics

I'll grade it a C-. You have more work to do. The small patches to cover holes are good, but then you need to lay a single large piece across the whole area to cover the patches to get a good seal. You need more work on the outer pannel first. The outer panel that makes the outside of the car door, I think you may have the terms backwards. The inner pannel is nearest you.

You need to lay strips along the seams from the top edge, wher the outside panel meets the sides. It may be too late to get to some of those places, but add as much as you can reach.

The big hole you have 2 choices. Do it right, or half assed. To do it right, you should cut a piece of thick MDF or plexiglass to fit the shape of the hole down to where the bars come in and caulk it into the whole, then lay deadener over the entire area. Cut a small slit for the bars to go thru, then patch over the back of the slit after passing it around the bars.

Half assed you can just lay a couple of layers of deadener over the entire hole and make the same small slits for the bars.

You should try to cover every inch of paint and metal with deadener. Thump across the outer and inner skins with your thumb to find weak spots and apply extra deadener there.

If your running out of deadening material, concentrate on getting the seams, edges and holes covered first, then apply the remainder on the large weak panels that will vibrate the most.

Also make sure you have a good seal around the speaker/driver.

Thanks, I know I definitely have more work to do, I paused trying to figure out a way to cover that one hole. I have deadener up at the seems where the panel meets and also at the bottom as well except for where the speaker will go, I will do that

Absolutely not. Generally with a genuine butyl-backed mat, you're good at about 65% coverage. His door looks like it's covered in RAAMmat, so it might need another layer is it's pretty thin and the foil is only 2mil.

Tap test is ok, but isn't all that reliable or generalizable to the real world.

Yessir it is Raamat, I have completed most of it now, I am just going to wait to do the final over layer until I get my mids and tweets installed, I don't want to trap the wire in until I know everything works and I have good connections, just have to wait for the cl-62cf's to come in

put flex loom around your rods, then seal the hole off. this way the rods still function like they should and you get that nice seal you are wanting

Great idea, I happen to have some 3/8 inch loom layin around

i just put a piece of deadener backwards over the metal so it didnt stick, but it would stick to the deadender i put ovre it.. to seal the hole with the door handle things.. worked pretty well actually

never thought of the loom idea, nice i like that.

yeah, i forgot where i read about the flex loom but it is pretty genious imo
