[How much deadener?]

It's a 2014 and has only had the set up in it for a week or so... I'll double check for loose screws but I think they are good to go... I'll look into some foam padding and also some second skin... Might do a bunch of padding and a little bit of SS... I had an 01 Blazer extreme before and broke the roof support bars that are welded to the roof itself and I put padding in between the roof and the bar and it stopped the rattle, but obviously I can't put padding in between the bar and the roof if it's not broke....Just want what rattling I currently have to stop, from an interior stand point

Damplifier pro. I'm not sure how much. Measure the length and width of what you want to deaden multiply them and buy a little more than that square footage. Alsowatch one of eds videos on showtimespl about deadening. He has some interesting ideas.

I'll do that... This is why I wanted to ask in here... I'm getting mixed answers on what to do to help stop the rattling / vibrations... I want to do it correct the first time

So that may be why they said to do multiple layers, to help the rattle... This helps a bunch because I could've spent a ton of money on something I don't necessarily need... So if I want to put foam padding on the roof to prevent rattle, would I just put it in between the headliner and the roof, or is there a trick to it? Also for the rear hatch, just in between the panels and the hatch itself?

Is there a certain type of padding to use, or just any foam padding?

So if I applied 1 layer of SS to my roof and my rear hatch, how much do you think I would need, and what specific SS deadener would you advise?

Well, some local people I have talked to have made it a point to tell me I should do 2+ layers... I have never used any deadener before so I don't know exactly what to expect... My goal is to tremendously reduce INTERIOR vibrations caused by the woofer... For instance, currently, on certain frequencies, my roof sounds like a bunch of metal slapping against each other and I can also hear quite a bit of noise coming from the rear hatch... My goals aren't necessarily to gain anything out of my set up. But I do want to eliminate as much as possible, the interior vibrations I hear on a daily occurrence

Looking to buy some deadener... I'm leaning towards hush mat right now, but it will depend on what type of replies I get on this topic...

I have a 2014 Ford Explorer with one 18 SMD and I am looking to deaden the entire roof, and the rear hatch, at LEAST 2 layers... My only problem is, I want to do it all at once and want to make sure I have enough for 2 or more layers...

As I said... I'm only planning on the roof, and rear hatch...

Any input on how much I may need would be absolutely great
