    I'd put one behind where the speaker goes, three more centrally located on the largest panel. The remaining two I'd put on the inside panel to help reduce any resonance there. If you can't fit three on the inner surface, do two, and put three on the inside panel. Use any pieces you cut or trim off, you are just adding weight to the metal to change its resonance.

    Any little bit helps! So if you have any left over mat left over, stick it up in the door! Don't waste any part of it.

    ok.....thanks for the responses.

    so..........can this stuff go over the vapor barrier instead of going inside the door and have the same effect? never done this kind of thing before(im more mechanical than anything else:)). all together...i have 12 sheets of it, so im hoping its enough for my 4 doors.

    If you get a chance to do more, I HIGHLY recommend Second Skin. It is my sound deadener of choice and the only one I carried in my old store. Very reasonably priced and much thicker than Dynamat.

    Not to mention Ant...the owner, is a GREAT guy!!

    You know what works great? Get a role of foam tape from an HVAC/R supply or a hardware store and make a gasket between the outside of your speaker and the plastic ring on the inside of your door panel and that will do EXACTLY the same thing and cost practically nothing.

    if you are on a tight budget go to home depot or lowes and get some roofing stuff, it comes in a roll. Like Blue says you just want to change the resonance. From what I understand the idea of the raammat, second skin, and the other stuff is a take off from the original roofing product. Better than nothing, I think it is cheaper as well.

    Roofing material is asphalt based. It is a HORRIBLE alternative because it will peel off. Eventually.

    Second skin, Dynamat, and others like that are Butyl based, so the adhesion is a 100 times greater!! I have used asphalt based deadener before, and learned from those mistakes.:D

    Peel and Seal is the roofing stuff. It works in a pinch, but as said, it will eventually delaminate. Also, there is some odor associated with it that is not present in butyl products.

    Evercoat makes great products, so Im not knocking what you used at all Will. Please don't take my suggestions as saying what you used is shit. Hopefully it was not interpreted that way. Believe me, when it comes to a budget, noone understands like those that are unemployed...namely...me. LOL.:D
