There are several subs out there for the amount of power you are looking to run to them that will take that safely
The BTL n2's,AA Mayhems,Lvl 4 XL's
Im pretty sure even the FI BL's will take that power as long as its clean
You can also look into Mmats DreadNauts and Juggernaut subs
DD 9500's and Sundown zv2's are nasty as well
All depends on how deep your pockets are
