I have a 99 tahoe. I was wondering if I would benifit from covering the whole car in brown bread, rear tailgate to dashboard or just putting 2 layers in the rear. I am going to have 3 jl 12's back there. I also have 140 sq. ft. to work with. Any suggestions.
U can always benifit from dampening!!!

What I am getting at is this, are layers of brown bread better or is more than one layer redundant.
I would strip the entire car and do the whole thing. You might need a little bit more then 140 sq/ft. The problem with just doing the rear is the truck acts as one big enclosure and the whole enclosure vibrates not just cargo area. I would also suggest that you save a little extra and once you get your sounds in, if you sill have rattles you locate them and then cover the car part or area with the extra Brown Bread. Here are some pics from one of my Brown Bread installs

That answers my question. Now I have another one. Is it a good idea to do the roof? I have not seen any like that yet but if it is the way to do it I would like to do it right. I would like to avoid having to though because I have rear A.C. vents, control panels, and such that I would have to deal with. My budget is not money but time. I am a college kid that works 40 hours a week.
If you don’t have the time then I would say skip it. Most of time you don’t get many rattles from the roof itself. But on the install without the roof you will be looking at about 3 days depending on how much experience you have with taking apart the interior and putting it back together. I would also suggest that you get a friend that mechanically is inclined to help you out.
That is not much of a problem. I took 2 years of auto-tech in school and am pretty good about most things involving cars, and interior is not a problem at all. Thanks for your advice. It think I will skip the roof.
