new system, 2002 gmc sierra 2500

Hey guys i have been away from the car audio scene for a couple years and now its time for me to hook up a badass system.
I used to go off of hear-say of buddies when it came to my systems but this time i want it done right.
In the systems ive had, ive had systems that vibrate my *** and back till they go numb and ive had systems that dont massage my back but hits me in the gut and makes me wana be sick.

Im going for more of the "tight" bass with optimal quality. i understand this comes most from a small sealed enclosure. im looking to do 2 12s and i want it to be as loud and tight as possible and there is not to much of a money limit on this system. like i said i want it to be badass.

I have considered alpine type r 12s with amp that can put out the subs rms. but i know there is surely a higher quality/tigher bass/higher power sub out there i just need to know what it is.

any help is appreciated.

heck out fi, audioque, digital designs, and ascendant audio. most of their subs like to be ported, but they will definitely get as loud as your looking for if you feed them proper power
