good 12's and an amp?

Hi,

I own the little brother to that amp the Brutus BX1500D and I love it, I have not got a chance to play with the new line from Hifonics, but I ve heard there actually better than last years, if you can get it that amp will put a hurting on almost any sub/sub's you put to it

if you are wanting heavy hard hitting bass you will want ported boxes i would go with a slot port and 2 12s.

i got a kenwood x811d 1600 watt peak 1 ohm 1100 rms 200$ ebay shipped http:///.com/dll?ViewItem&category=79828&item=5783259487&rd=1&ssPageName=WDVW

Nodestiny had this right.  We need more information. 

The number one piece of information we need is this:

How much space do you have to dedicate to the subwoofer's drivers.  This will totally dictate the rest of your decisions.  It would be foolish to even think about anything else until you've determined that. 

Seriously, this will affect the box size, sub size, number of subs, which subs will work, amplifier, everything.  The space you can dedicate to the box is the starting point in sub bass system planning.
