I'm going to put dynamat extreme in my trunk. Will it give me that much more spl? Will it increase my SQ? Is dynamat even worth the money?

You won't notice a huge difference, but it definitely helps. Anything you can do to help deaden the car is good. All that rattling and stuff vibrating is just a waste of energy, that could otherwise be used to create sound.

I personally think regular Dynamat is a rip-off, the product is good, but there's plenty of other brands that work just as well for a lot less. (Sounds like JL, hehe)

Yep, I used eDead in my car. There's a few other brands that are very similar too.

There's a few differen't liquid sound deadeners - they work good for tight areas and sharp corners/edges that it would be really hard to put a mat on. The liquid stuff looks better since it's one big perfect coat.

The roofing stuff from honedepot works pretty decent. I think it may have tar in it though, so on hot days it stinks somewhat.

dynamat definatley helps it made my subs sound better on the higher fq b/c my trunk would flex and all i could hear was the metal rattling. it makes the subs have a clearer sound also depending on much dynamat you use you will notice a big increase in spl. on the Dynamat packaging it says if you use the full extreme kit in your trunk you could have as much as a 3 db gain. if you go w/ dynamat get the extreme the original sucks doesn't stick to wear you put it and not as easy to work w/ as the extreme.

" the original sucks doesn't stick to wear you put it and not as easy to work w/ as the extreme."

You need to heat the orgininal stuff up. Believe it or not, I used a little mini torch to heat my eDead up, just hold it far enough away and the stuff gets warm nice and fast...

sound deadening material will also make the system sound better from outside correct??? You will hear just the bass hitting, and not the trunk/car rattling... right?

Sound deadening is meant to keep the sound IN. If your car is properly deadened, you shouldn't hear much from the outside.

joe i kow you have to heat it up. since i live in florida i used to set out the dynamat outside for about 10-20 min( during the summer when it's almost 100 out!) and then i would go to work but even doing that the orignal just obviously isn't as good as the extreme.

mike yes and no, if your subs don't rattle a whole lot to begin w/ and you sound deaden the entire vehicle you may not be able to hear bass outside the vehicle at all. w/ my car it still rattles a little but you mainly hear the bass and not the rattling of the trunk.
