I got a 97 2DR Explorer Sport...

I want to sound deaded the hatch probably in the most cost-effective manner. I'm looking at getting some Blue Skin.

Anyhow, I am wondering if I just did the hatch what kind of a gain would I get? I point the sub toward the back to load off the rear hatch. With the windows down the hatch rattles noticably. With the vehicle sealed up the hatch rattles like a jackhammer.

The other thing I am worried about is how much louder this will make the vehicle outside... because if the change is that dramatic then I'm not losing that energy to vibrations. If this is the case then I'd probably have to do the whole vehicle over a couple times.

Kinda hard to say what kind of gain you will get but you will be surprised. Even if you can only do small portions at a time, it will help greatly. As far as it affecting how loud it is outside, I guess thats kinda tricky to say, you would be eliminating that crappy rattle noise and would hear more of a bass sound, but also your are containing the sound more with the deadening material to where it would be louder on the inside. If you can afford it and have the time, I say strip that bad boy and layer everything once or twice.
