Ohhh alright that's what Im going to try to do is put dynamat on the front doors. How thick of a dynamat sheet would I need. I saw on the dynamat website that they have a 1/2 inch sheet available. Or do you think 1/2 inch is too thick, especially when I put everything back together?

Where do you think the rattle is coming from? If its road noise, then that is hard to stop and would involve taking the interior out. The easiest thing to do is dynamat behind the door panels and that will cut down on nose significantly. Dynamat is easy to put on. Peel the backing off and place it where you want it and use a small roller or even just some rounded object to get it flush against the door

Well I won't be putting anything new or anything new in terms of audio in. I just want it not to rattle as much as it is doing right now. Since this is an old car the audio might not sound as great when it was first put in. I heard about dynamat, I just need to take some time and actually put it on which sometimes I don't have. But I will look into it.

And also I know that the highs and low don't sound as great with these bose speakers. I use the pa15-nis for my ipod and I can hear that the bass as not very deep as I want it to be.

Hey I head you are good with audio. Do you know what I can use to reduce the rattle with the bose radio. I have a 96 I30 and I was wondering what would be a cheap solution? And also could I use fiber glass insulation in the door panels?
