i'm thinking about either getting 2 fi bl 12's or 15's. i was wondering what would be better for sq and spl if it's hooked up to either a audioque 2200d or a sundown 2000d?

Way too much info here to make a guess.

Dumb it down a little and let us know how much space do you have top work with?

I have alot of room for any box so that isnt a big deal. im doing the big 3 upgrade getting a 220amp alternator, and xs power battery. what else do you want to know?

What is a lot room? What car?

No one can give you an educated opinion if they don't know how much space you have to build an enclosure.

So it kinda is a big deal if you want it to get loud or sound good.

I have a 1999 JEEP Cherokee Sport (54" (L) x 38" (H) x 31" (W) )

OK i'm getting 2 fi BL 15's powered by an audioque 2200D with knuknoceptz 0 gauge wire. The box will be 7-8 cubes with 12 sqin of port tuned to 33
