I was thinking about that, but the Amp(s) on the ceiling sounds much nicer. There is a shop not too far from where I live that does almost anything you can think of and their quality is great! I want to mount the Amps to the ceiling, and lower the headliner from the "rib" on the ceiling between the rear doors and the rear door. The way I have it sketched out it looks really cool, now I just have to wait a year to get my car back!

A sealed box plays tight and controlled better less sloppiness. Sealed boxes can get loud, but require more power than ported for the same volume. Ported boxes are more efficient and get louder with less power. If you are running a smaller amp, a ported box will be louder. I'm running 1100 watts to my two 12's in a sealed box. The freq response is excellent with them. They get rowdy when I want them too, but are clean and controlled at the same time.

Not to dig up a old thread but this is not completely true. Theres sooo many variables when it comes to box type and design. Sub's also some don't work well in sealed environments and some don't work well in ported environments.
I've created a few ported enclosures where the frequency bandwidth of the enclosure played all within 1.5dB of each other on a 50hz bandwidth. Then of course EQ'ed it to play a little flatter but that'n not my point. Typically people don't know how to design ported boxes for a "SQ" type environment. So to say sealed sounds better and plays smoother than a ported enclosure.. not true. You just got to know your vehicle's response and what the sub's like which comes with some testing, can't just drop-in and expect awesome results. This is science after all lol
