Sub help, 8" subs in doors Options

[d3ath2009]

i have a 97 with the 4 speaker system and i want to replace the door speakers with some 8" subs, but i dont wanna buy any then find out they won't fit..... what's the max depth?? do i need free air subs??

I had some JL 8w3's in my door and they added a real nice bass and great frontstage as well, only thing I didn't like about them was my doors would always rattle(but I have shaved door handles with solenoids in door and window control module in my door too-so that might have been it).

rattle went away if I upped the x-over point, but then whats the point of having subs in your doors right?????
So I ditched them.

I ended up doing some MB QUART Q-line 8" components bi-amped off of an old school PPI competition amp, crossed over at 75hz.
running 2- 15" Alpine R's tuned to 30hz on a ton of power is one of the best sounding setups I have.

I am about to take out 15's but no matter what I think I am keeping the 8" MB's bi-amped .

Also I think Hertz has an 8" component and for the price on most of the hertz line they are amazing.
I have heard baseline Hertz 6.5 components and they blow away Alpine's and even the JL ZR stuff!!!! so even if you do a 6.5 hertz sounds really full and has great bottom end, if you want something really BRIGHT with alot of tweeter go MB reference of Q-line
