Hey Ben,
The initial build is done on the 10" Bazooka

I also replaced the rear sub (That was blown all to hell, thanks to my sweet daughter(s)) and have replaced them with 2-200 watt AMPS. One is driving the Bazooka and the other is driving the rear speakers.
I also finally installed the front pillar tweeters that I salvaged out of 99 LR and got them hooked up.
The tube is mounted in the right rear window (top) where I talked about putting it. The build looks pretty good but, I have some reworks that I want to do to it before I paint it.
I cannot believe how great it sounds. I was going to replace the front AMP under the passenger seat but, it sound so good I think I will leave it as is. The crossovers for the tweeters really made a big impact on the sound from the front speakers, with just mids and bass flowing through them now.
The only sad thing that I am running into is that I am not happy with the head unit for a number of reasons and think I am going to replace it. I really love the remote buttons on the dash but, when it comes right down to it I think all the newer innovations ie..Satellite, DVD capabilities, and so forth make it worth the upgrade. (Plus more slots for future built in electric switches:))
And last but not least, I have been dying to utilize my Blackberry 8830's ability to be used as a music player.
I bought the following for this portion of the project:
