XXX Subs and Audiobahn amps

Hey I am new to the site , but been installing since my first car(5 years).  I recently had all my gear stolen, stripped and left for dead out of my car.  Insurance gave me some cash and I was looking to head in a new direction.  I had an MTX setup but I want to try somthing new, I am speaking of RE XXX 12in subs and Audiobahn amps.  If you have any experiance with either let me know good and BAD...I am looking to do a 4 12 setup and run it off 2 2300hct amps, components and head unit are still up in the air.  They will be in a Parallel setup with a 3 chamber bandpass box, 1 box for 2 subs so 2 boxes total.  Let me know what you think, and yes I am crazy so you need not ask..

What kind of bass do you want.  IMO get rid of the bandpass, they do not pressure up that well and they sound too boomy

I am lookin for big burps, this is not for a daily driver.  I would lose what little hearing I have......
