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 really suggest having a look at component speakers in the shops etc.There are speakers that can play as low as 50hz and I find it unneccessary to even run a sub at times.

whatever speaker it is, be it a 4inch one or a 12inch sub. The main thing you need to do is to separate the back wave from the front wave. Speaker has sound coming from the front and its back(magnet) since it is just vibrating and moving air. If you dont separate the front and the back, everything would suffer. bass,quality etc etc.

in the doors, the inner door skin(where speaker mounts) separates them to an extent(very minimal). To go one step further, people use sound deadening on the inner skin to slow down the backwave even more so that it doesnt not interfere with the sound in the car cabin.

for a subwoofer, the 18mm mdf does that job.

hope it is easy enough to understand. for those who are jumping around thinking of dipole etc...can leave that for another thread.
