Dynamat for the rear deck.

1998 Mazda Protege

I am going to buy 1 (one) 32"x18" sheet of Dynamat Extreme and I am looking to make the most of it. The problem areas for vibration are the front doors and the rear deck. The front doors currently house stock speakers but buzz at the slightest hint of bass. The rear deck vibrates quite violently when the volume is turned up, thanks to the aftermarket Pioneer 6x9 3-way speakers I installed.

I have two questions really. The first is "Should I put the Dynamat on the top or bottom of the rear deck?" And the second is "Should I use the entire 32"x18" sheet on the rear deck, and simply get more for the doors later, or should I "spread the love" so I can quiet the entire car a bit right now?"

The reason I'm only getting 1 sheet at the moment is my budget...it's small.

Increase your budget, borrow the money and pay it back.  Get those doors, rear deck and trunk lid done at the very minimum.  The doors should be covered not only on  the panel that the mid attaches to, but also on the outer door skin.  The rear deck gets covered 100% (which side of the sheet metal doesn't matter), as well as the trunk lid.  There is usually an area on the back of a car under the trunk latch and between the lights that needs damping, too.  Do it right at one time while the car is torn apart or you will be forever bothered by those nagging little noises.

Come on...you're asking for this forum's collective insight into how you can stretch a little piece of Dynamat?

Thanks for the reply,

I was actually more concerned about the first question, because of all the clips etc. that go through the rear deck.

For longevity of the material sticking to the car, and the usually unsightly shiny material, I would suggest you take the time to remove the rear deck and apply the material on top. This also may keep the metal deck and fiber board from bouncing together.

However what stevdart mentioned is very useful info, and i too would take heed to it.
