Questions on sound dampening.

[stay_high 10+ year member]

Just got done sound dampening my trunk. I used the nvx trunk kit. only used like... 2/5ths of it. So i still have plenty. However it didnt really seem to stop the rattleing much and there is no difference in sound on the inside. I didnt use the roller that people suggest but i did use a crappy one i got from walmart. It is all stuck on there good in between the crevices and everything. Looks fine. Is there supposed to be an audible difference from one layer of dampening on the trunk lid?

So heres my main question. Should i use the remaining deadening sheets to put ANOTHER layer and mabey even a third on the trunk lid or should i use it elsewhere? Like maybe the door panels? Or should i rip off the deadener thats currently there and do it properly with a roller from dynamat or whatever? My sub stage setup is in my sig. Oh and i drive a 08 ford focus sedan. Believe it or not, its a rattleing piece of **** that doesnt seem very well built as far as the door panels and what not go.

Thanks for any input.

Honestly i didnt notice to much of a difference until i had done all the problem areas, after doing the trunk lid the rattles just move elsewhere. Now after using great stuff inbetween panels, and sound deading the rear dead on top and bottom, 2 layers on the trunk, both doors, the roof, and behind all the plastic panels i have no rattles at all.

Also tightening the trunk as much as you can will help stop rattles as well.

SO let me ask you this, after all the money spent on deadening your ride was it worth it? does it really sound that much better?
