I am planning on adding a 12" sub in a sealed box in the trunk of my maxima. With this scenario, will there be a lot of rattle like those idiots in my town or will I need dynamat?

 

I have two twelves in my car I have some rattle but nothing Dynamat can't fix!

 

even with dynamat, theres always this strange rattle comming from the trunk latch which is hard to get rid of.

 

Every car will be different, but you're bound to have some rattles, even with a single sealed 12. When I first put my sub in, I didn't hear any rattles, but after about a year I have plenty. It doesn't really bother me too much because I can't hear the rattles inside the car.

 

Thanks for your help guys.

 

I added that funky expanda foam junk inside the rails on the trunk lid, from there, I installed an Extreme Dynamat trunk kit. Now the only rattle I have is from the license plate. It's getting a piece of Dynamat today. Not only that, but that cheap sounding thud from the trunk is now gone as well. There's pics on my web page.
