opinions on sub options

hey guys. im pretty new to car audio but right now i have 3 of the lower end pioneer premier 12's in a ported box running of a hifonics bx1505d at 2.7 ohms.  sq sucks, but they are pretty loud. definately the loudest ive heard in person, but i havent heard too many top notch systems so thats not really saying much. but i got a new job recently. its at best buy, so im limited on selection, but i can get type r 12's for $100 a pop with my discount. i dont like the three subs because the box i built takes up my ENTIRE trunk and doesnt give me a lot of room to make my trunk nice n purty. im thinking about going with 2 of the type r's in a ported box because i think they might be a little better sub and i can free up some more room to build a more "aesthetically pleasing" trunk. with the 2 12's i would be able to run the amp at 1 ohm, giving me more power. but i dont really want to lose output. so of these options, which would you choose and why?

1)keep it like it is, its already loud

2) ditch one of the premiers and just run 2 of them

3) spend the $200, get two type r's

thanks for everybody's input. it is much appreciated

ok guys i know that the type r's are pretty nice. we've done some installs with them and ive been imressed. my thing is i dont know how two of them are gonna sound compared to the three that i have now. but at the same time i know more doesnt always mean better with subs so i just want to get some input  on that
