Hello all, this is my first post here. I used the search function and didnt find an answer to my specific questions, so here goes:

1. I am installing 100 sq. ft. of B-quiet extreme in my '91 4-door lumina. underneath the carpet there is some stock sound deadening material. Should I rip this out? Or put the b-quiet underneath and put it back?
I was thinking that the stock deadener would actually deaden the sound (energy lost), while the b-quiet (and all the other variants of dynamat), are different, in that there isnt energy lost, and the music is therefore louder (Am I out to lunch on this one?). If this assumption is correct, then the stock deadener should go.

2. Should I put b-quiet behind the rear seat? (on the mat that is right behind the rear seat, which separates the trunk from the rear seat). If I do this, wont I be sealing off the trunk from the rest of the car, and making my subs quieter?

3. Would it be beneficial to put b-quiet on the rear 2 doors, even though there will be no speakers in these doors? I guess I am asking which places in the car should I concentrate my efforts, for best results?

I agree with DWVW. Use your ears.

I've installed less than 80 Sq feet in my entire vehicle, and it made a big difference.

Have fun.

Do what DWVW says, don't separate your trunk from your car, it will make your subs quiet. If you make a list of places you need to deaden, the rear doors would be near the end. 1- front doors 2 front floors, and firewall. 3 roof, 4 trunk, 5 rear doors, etc.

 

Thanks for the help guys!
