After a lot of questions asked and answered here and elsewhere, I finally installed my dual JL10W6's in a sealed box, in the trunk of my 09 Si Sedan. I am powering them with an AQ1200D. I also have 4 Polk 651's powered by a Kicker 200W amp and a Clarion Max685BT head unit.
I'm not a competitor or basshead, nor am I a true car audiophile, but I did want a good sounding system. To me, this system sounds great! I have all the volume I wanted along with great bass sound quality that I just wasn't getting from the Fusion 10" 300W bass tube that I replaced.
A lot of my questions had to do with power issues. I was paranoid about over taxing my stock electrical system. I ended up following the advise I got from DJ at Audio Que and installed his 1200D without any electrical upgrades to the stock system. He said as long as I wasn't a basshead, I shouldn't have any trouble. I have to say that everything had been running great, without any dimming or anything, however being the paranoid person that I am, I did install a Kinetik HC1400R just to make sure I wouldn't have issues down the road. When I did this, I added a 4 guage from neg to ground just to make sure.
Anyhow, I just wanted to let everyone know that my system could indeed handle the power I required without issues and that I am happy with the performance of all the components I used. And thank you to those who answered my nubee questions.

 

Sounds like a good setup
