Alright I have a 95 blazer 4 door and i just put 3 subs in it with a preaty big box for the subs, and when i turn it up everything just rattles all over, so i need to kno how can i stop this? i kno that i can use dynamat or some sound dedener, but there are crazy spots on my car that rattle like my back door it just goes nuts and then my back apillers are goin crazy so i was wondering if anyone had any ideas how i could fix this without welding my doors shut or making my car look rediculously goofy.
You already answered your own question. It's called damping, and it's known as Dynamat, among other names. It's gonna cost some good change, but that's what you need to do, you can't get away from it. Some places are obviously going to take more...

It all reminds me of something that Molière once said to Guy de Maupassant at a café in Vienna: "That's nice. You should write it down."
to save some money they have cheap spray on sound dedening stuff at wal-mart instead of paying 20 or 30 bucks a can for the dynamat or RF stuff i would get 3 or 4 cans of the spray and get a dynamat trunk kit that should grt you by

And if your vehicle is really RATTLER-ing, you gotta find that snake and get it out of there before it bites you.
