140db possible in this setup?

Hey guys I need some info from the experts here. As you all know I am looking to have a 140 db+ daily driver. Now this car is a trunk car (ford Taurus) I want to get 2 AQ HDC3 12's and 2 AQ1200D Amps. If I build the boxes properly, face the subs and ports to fire into the cab of the car, and seal the trunk off just behind the subs could I be hitting 140's daily? Thanks guys I just want to make sure this is possible before I drop the money on them.-ETS-

Anyone? lol even an educated guess would suffice at this point. lol-ETS-

I say no, not unless you tune those woofers around 60Hz or whatever is the resonant frequency of the vehicle and that's way too high for a daily driver.  fs is too high and sensitivity is too low.Support the12volt.com

Ok guys thanks for the input. Im was going to tune the boxes to 37Hz. Do you think I should tune it lower and design a good ground pounder setup? Im ok with the alternative since 140 seems unreachable.-ETS-

Model it first.  Those woofers will have very little output at 37Hz.Support the12volt.com

ok thanks guys for all your input. i have done some research and thinking and what ive come up with is i dont necessarily want to have a daily spl car. i think i want a daily ground pounder. something to wiz off the neighbors with. i am thinking about getting pioneer premier 12`s the ts-w3002d4. i would get 2 and build the box how i previously stated. what are your opinions? these subs fit a little nicer in my budget and seem to be on par with the aq hdc3s as far as t/s paras go. how would i want to tune the box? low or higher? i dont mean to seem like i ask a ton of questions. im just trying to learn.-ETS-
