Four fi bl 15 box design

Hello I have a jeep srt8 with two rockford fosgate 1500.1 bcd's and four rockford p3 15s in a custom box tuned to 35 hertz. I want louder now. I've been hearing alot about the fi subs. I wanna keep my amps but get four fighteens that will do great with my amps. Both amps comined will do 3900 watts rms. I've been looming at the fi bl line. They are rated at 1000 watts rms 2000 peak. So if I had four Of them they would be 4000 watts rms , I would only be shorting them 100 watts. My question is can these amps slam the bl pretty hard and can I use my same enclosures I have now with 12 cubic ft and , 6.1 per chamber for two subs on each side and tuned to 35 hz. Basically each sub will be getting 950 watts and 3 cubes a driver. Also with the amps I have will this setup be super louse in my truck. I want that bass that will make your head hurt and be hard to breathe and swallow.
