EDIT - UPDATE COMPLETED 07/08/10
Finally completed the build and am very impressed with the results both visual and performance wise here are a few pics, as always comments and critisum welcome 
Just thought i would share what i spent today doing...
Fitted into my car:
2x JBL GT5-12 12" Subs
1x FLI Loaded 900 amplifier
1x ProSonic 1.0 Farad High Performance Capaciter
A lot of MDF
And a lot of 8AWG wire
Still needs to be covered and a pvc sheet place over the amp but looking good for 1 days work i think, Let me know your thoughts people

EDIT:
To test the full capabilty of the amp without having to worry about my new subs getting blown i wired up my Class-D 15" subs from my house and the power the amp gives is unreal, Loved it

P.S all controlled from a dvd flip out 7"screen head unit in the front of the car (look carefully in the pic and you will see it)
EDIT;
After buying audio carpet i decided i no longer liked the layout lol so i completly ripped it out and started again, then started to carpet the new build, its not fully carpeted yets only partly as the un-carpeted sections i want to use blue audio carpet but am having trouble trying to find any for a "reasonable" price. But here it is at the moment... (also have a 12" blue light to stick behind the amp that still needs fitting)
