Looking for some info around sub brands and specific models to fit my application (daily driver)

[jbeez]

I have a '11 escalade with the short cargo area, I pulled out the third row of seats and have 2 captains chairs in the second row. 

 

I have an aftermarket headunit already installed(sony XAV-9500es), underhood two xspower D4900 batteries, mechman 400A alt. Big 3 all handled.

 

I'm about to run 2 2/0awg wires to the trunk, deciding how(probably through the huge factory grommit, can't find an easy place to drill for 2 cord grips in FW)

 

I have a stinger mt 4000.1, seen these dyno on BigD's channel at like 6000watts 1ohm.  The card supplied from manufacturer shows it doing 4677@1, 3168@2ohm,1721@4.

 

I'm at the point now where I think I want either 2 15" subs or 4 12" subs in a ported box. Don't need competition stuff to do demos or burps I just want some serious bump when I'm driving around. I also have a kid a need some cargo room so I don't want to use ALL of that cargo area, I think I can save the back half for storage.

 

My question, which brands should I be looking at? If I do 12's I probably want something that does 1500w-ish each and 3000w/ea for the 15"s?

 

I was looking at PSI, Fi, Sundown, Stereo integrity, B2.

 

B2 is confusing, they have several models/versions of subs, a lot of stuff out of stock, they keep revising their design? Sundown and Fi also leave me spoiled for choice and its confusing.  I am very familiar with PSI subs, I have 2 12" p2HD subs I've had for over 10yrs and they are incredible. 

 

Thoughts? Suggestions?
