Help choosing speaker setup for 2011 Nissan Maxima SV with 7,000 watt subwoofer setup

[iCarfly]

Right now I have installed..... 2 15" Rockford Fosgate 15's at 1200 RMS each, and a lot of HSK 165 XL's in my Nissan Maxima. It sounds very loud and clean, but only hits up to 125 db. I want it to get a loud louder, but still sound clear as day.

So I've ordered 2 level 5 DC Audio 15's along with two of their 3.5k amps and wondering which speaker setup I would need for this to sound really good, clear, and insanely loud.
