fiberglass over deadening or just carpet?

[snebes]

I am building a box out of my entire trunk pretty much. The long, flat back, top and bottom will be layed out with 3/4" mdf, while most the rest will be fiberglass. Would it be best for me to deaded the trunk completely first, or just build the box in? I would be using SS Damplifier Pro (possibly try out hazmat, gonna call anthony for more info on it) either way. This box will hopefully be close to 10 cubes with a port, but have yet to get a somewhat mathematical measurement...working on that now

I would mat it first. would **** to lay all that glass and have vibrations also it will help your bass.

That is what I was leaning toward anyway. I don't know how long I plan on keeping this car, so I didn't want to put too much deadening in it, but I guess I could go all out and keep it as a demo car. Guess I should estimate how much deadening I would need then for the whole trunk

well you can always carpet over the mat if you sell it
