I don't know what would have caused the seal to break, but it did.(photos below)
I re-applied liquid nails to the area. i also applied a 2nd layer of liquid nails to the parameter of the sub cut-out hole to ensure integrity. I let the box cure overnight, then drove to the car show on Sunday.
Thursday night's sound test was nothing compared to Sunday. The FI Q's true sound came out in all it's glory on Sunday. As far as SQ goes, it effectively reproduced clearer bass notes than the RF T1. Excursion was phenominal. I got this sub jumping at least 2 inches from it's frame, and holding it this time around. It kills the lows. My entire hatch rose as the lows hit. The only thing holding the hatch down was the fact that it was closed and latched. The rear windshield wiper was taking a beating too, wobbling violently, litterally jumping off the glass. I also witnessed the sides of my rear bumper flexing as the lows hit. Luckily I have the entire rear hatch Dynomatted. If not, the rattle would've probably been pretty bad.
I had many audio enthusiast coming up and asking what I had in there. They couldn't believe it was only one 12. One guy said, "Man, that sounds like three 12's!". I also had a few audio enthusiast compliment me on the sub selection. The sound system seemed to take away from the rest of my car. Alot of people ignored the rest of the car and went straight to sticking their heads in the car to listen.
My final conclusion is the FI Q is a superior sub to the RF T1....

your sub at $ 250 kills most $500 mainstream subs
non-mainstream for the win

This is kind of what a lot of here try to tell people when they ask for advice. It's not that the mainstream companies put out garbage products (well not all of them), but that the prices are so inflated due to marketing costs.
Where's doug and his red pill/blue pill picture!!!!!

they spend a boat load of money in research and development , the have board of directors , the have CEO that want vacation homes
therefore the price of their items is high
now i prefer to buy my product from owners and engineers that actually do it for the passion of competition premarily , and to get rich secondarily
Scott at FI and the boys at RD actually compete
would you rather buy product from a company trying to dominate thru wins at competitions, or from a company trying to justify 4th quarter earnings to a board of directors

Alright VO, you sold me! Or, should I say, your results speak for themselves and they sold me on this driver. I've never been a "give me the same thing he got" kinda guy, so two JL's in a Zenclosures with a 1000/1 just was never gonna happen for me. So, when you see this post, could you tell me where you got this 12" FI driver?
My standing design requirements for the sub-bass portion of my in car audio/video system are:
* Retain spare tire
* Stealth/OEM-"look" install
* SQ. "Tight" controlled bass. No "boom". No slop. Think "punch in the kidneys".
This driver would further refine the parameters of my install to include:
* ~ 1.55ft^3 sealed enclosure huh? (as I understand it from perusing this thread lightly)
If that's the case, that's a relatively small sealed box, I've got a vision coming together in my head and I'm thinking this is do-able.
Thanks,
Clark

1.55 cu ft. is actually too large, per the website. For the FI Q 12 you can have a sealed enclosure ranging from .8 to 1.5 cu ft. Mine enclosure is closer to approx. 1.3 cu ft. of usable airspace.
It hits the higher bass notes real tight, since it's a sealed enclosure. At the same time, it'll dip into the 20 something hertz range also. Either way the sub reproduces the notes extremely clear. Just make sure you have absolutely no leaks in your enclosure...

fi Q 12" .8 to 1.5 net dual 1 or dual 2 1000 rms $ 259 shipped
fi ssd 12" .8 to 1.6 net dual 1 or dual 2 800 rms $ 189 shipped
look at what i am posting , match your rms, budget, and net sealed space to pick the correct woofer for your best results
either will be better than a W6

It actually made the bass sound more clear than previously, as it took some of the upper frequencies out. I had it previously set to 100Hz cut-off.
