8-inch door speakers Options

[pepsiman]

I was thinking about putting some 8-inch subs in my doors but i just read that it will rattle the doors real bad...what can i do to prevent this? I have never opened up the guts of my door can u put plenty of sound deading in there? Will that stop the rattles? Also does the subs in the door have to be shallow mount to fit? What is a good 8 inch sub? pionneer has no 8's on their site but primeir does but they are alittle pricey for me i dont need anything crazy just wantin to add some bass but it dont have to be crazy

I put Dynamat on my outer door skin and it didn't seem to help too much. I have a friend who says stuffing carpet pad into the bottom of the door works well. I'm going to try it myself here in a couple of weeks, although I'm wondering if there will be a problem with it retaining moisture?

Also, I did not buy free air subs. They sort of thwack when they hit hard. Anybody know if installing a baffle would help the speakers perform? Trying not to spend too much money here.
