Sundown 100.4, Rockford T2's up front, what in the rear?

[triplec19]

I am new the mids and highs and have started my build with a sundown 100.4 I plan on running a set of T2's up front, i love how loud they get and loud is what im going for.I have a DC XL 15 on a 2200D in the back that i need to overcome. I have an explorer and Im wondering what to put in the rear doors. What would be the best another set of T2's or a decent set of mid bass drivers just to fill in the back. Like i said loud is my goal with SQ is important as well but they will be saved for when I have a more expensive ride. Please guide me making an educated solution to maken my truck be heard from a block away. THANK YOU
