New install opinions, midbass?

I'm planning the install for my newest vehicle a nice gas saving 94 honda accord.  I've been searching the forum for a few days for different ideas that i've been contemplating.  I have an alpine 9831 in it now with the factory junk, but in the garage I have a jl 300/2, a kicker kx 600.1, a set of diamond s600s, and a cdt es-sq12.   I thought of maybe trading out the diamonds for cdt braxials simply to be lazy and drop everything in, because if I have to use the diamonds I basically have to go in the sails and I'd have to fab something.  Then that made me think that if i'm going to have to make a mess I might as well make it a project worth doing and make some door "adjustments" and throw in a 3 way setup.  I had some Jl 8w0's a while back and I dug the way they made the double bass in metallica sound.   I thought about making kick pods but it would eat up the already small space for legs that there is.  So that leads me to my question.  I'm at a loss any new ideas other than these,

1. just be lazy and trade my diamonds for something that I don't have to mod anything for.

2. make some kind of change to the door panels and throw in some 8's with the s600's, and get a different amp.

Just two choices but I'm thinking I'd like to got with number two.  I just don't have any ideas on what to make, or if I could just throw the 8's in some new holes I put in the rear deck.  I don't know how good of an idea that would be though, as what I have read suggests the best spot would be up front. 

So just curious for your opinions.  Anything will help.
