I just upgraded from the stock speakers to some SSL 225 watt 5x7s(which are awesome by the way) in my 2001 Regular cab. I would like to add some soundproofing to the truck.

I have heard lots of different things on soundproofing. There seem to be a lot of Dynamat people out there. There are also lots of other people that say dynamat is awful. There are still even more people who put things in there vehicles such as "peel and seal" and other roofing products.

So I have a few questions:
How many square feet of soundproofing material do I need to do it right?
What is the best bang for the buck?
How long will these Dynamat products last in Texas summers (110 F at maximum)?
What else do i need to know?

Any and all constructive and positive feedback will be appreciated as always. Thanks guys.

Dynomat will work well.
Asphalt products will melt in the Texas heat and make a mess.
I've seen thin foam insulation used ... thot it was on this forum.

Awesome thanks. I was planning to use Dynamat and a layer of carpet padding. Any idea how many square feet I will need?

Nope. Sorry. I do know that even just enough for around the speaker installation areas makes a huge difference in lessening speaker resonance/vibration.

Is audiotechnix any good? From what ive seen on youtube, it is much more durable to heat and wont come off. Does it block sound better or just as good as dynamat?

egg carton foam in the doors, seal off the door holes with sheet metal or w/e, the place dynamat on top. alot of people use peel and seal but ive heard that it smells, especially in the heat so i wouldn't use it in a cab, maybe in trunk but thats it. heres and good guide guide.
