I spent a comparable amount of time setting up my front end last year when I built my car. I am a certified Iasca judge and work as an installer. If you wish to look at my car please go here http://car_audio_guy.tripod.com/Terry/Pictures or here is an older system, These kicks were not built off the panel are were a little larger. But hey it worked It finished 5th at 2000 World Finals in Nov 1-150 http://car_audio_guy.tripod.com/Julie/finished.html
These Panels are built off of replacement factory pieces and are a baffle NOT a sealed enclosure. I recommend filling the area behind the panels with fibrefill.
