Strapped or Not Strapped Ohm Box Rise Help Needed

[jeep187]

I have 6 Crescendo 12s DVC 4ohm Running in Series/Paralel to 2 Crescendo BC5500 Strapped.

I am getting an average of 6ohms Box Rise and seeing about 8k.

Would i get more power and less box rise if i run 3 subs in Parallel/Parallel to each amp seperately?

Thanks in advance. Any and all imput will be appreciated.
