Going to re do my system so come at me with your ideas

So my wife is down Haiti for another month yet and I'm driving her car. I now have the ability to take the taco apart. It's 3 am here I'm at work very bored and was thinking about a new project. Why not do my audio in truck all over!! Here's what I want to do. I wanna put my eclipse 4 channel in the bin below the seat. I don't know how to do this but know people have done it and I have seen photos. I'm going to build a new box but add an extra sub. I want two 10's. I will probably mount my alpine sub amp between subs along with my cap and crossovers. I'm gonna try and find the best deal on quality deadner(advice on product) and do the whole truck top to bottoom. My 8120 is all good to go on install so we are good there. What I want from you fine people is install advice. How would u go about it. What have you done what you like and dislike.

For you military people out there,,,,, anyone stationed in Norfolk? Come up to nob if your bored and spend some time with me. Could use the help. I will be doing a lot of work at home to and I live off of granby so if u want to put a few down and do some fun system work let me know. I know you guys r out there cause we've talked!
