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

thanks for the reply...i thought there was a how to on how to put subs into your doors the reason i was considering this is i already got 6x9s in my trunk and i didnt want to throw another box back there and have all this stuff then i thought of that how-to about putting them in your door so i figured that was for me cause I was wanting to add a sub or 2 plus a amp but i wont be doin this for a while i need more money and i want to do it right with a good amp and wiring so has anyone put a sub under the front seats? I think ive read bout that somewhere but i wanting opinons would it be muffeled?
