The huge CF dustcap also points at the 9500 series. If you can get me a pics of the sub's motor I could tell ya for sure what motor those subs have... Good luck with the finals, I always found dressing up in a 3 piece put me in a perfect mindset for finals week. (And it impresses your profs and friends too.)
Bigkahuna808 - SPL estimates are difficult at best much like guessing crank hp after a bunch of mods.
As best I can tell that box is sealed, so with the cut through it's going to act like a 4th order box a little bit.... If sealed and on 2000watts he wont see a 150 legal on a newer TL or the spl190 from AC, but he should be in the low 40s... If he uses an older meter either TL/AC/hydrophone mic he should be near 150s leagal. If he opens a window/door you should be over 150 on the soft, older mics as that is outlaw metering. If he outlaw meters on the new TL/spl190, he might get to the upper 140s...
On the new TL everyone is struggling just to get into the 150s legal. Some need as little as 4000w rms. Most require 8000 watts rms minimum to get there however. The new TL is a bitch.

Ive seen someone do 150+ legal & on the dash... it was in a buick rivera w/ 2 x 15" 3500 DDs... and that was with a cheapy "Merlin" brand amplfier at most 1500W. And yes.. on the new TL setup...
As for some clarifacation to the setup posted here.
1. The box is a ported enclosure.
2. Those are the NEW 3500 series 12" they now have basically the same motor as the 9500 series. The Carbon Dustcap is available on any 2500 series sub and up.
3. Right now he is only getting 1000W to the subs due to a shipping mistake from US Amps. he got the US 2000 instead of the 2000X... He's only getting bout 1/2 of what the amp can do. and it was hitting loud enough to vibrate an entire wall of a steel building it was parked outside of.
