they are, but would a bigger box make them louder

i found the problem, the settings on my deck weren't set right. These things hit so hard, thanks everyone for your help.

also the bass faids after the first bass note could this be because i have 3 amps connected to my yellow top in the trunk and there is not enough power

They are in a chevy malibu, im looking for spl and i have 2 hifonics titan 1000d's

I just got 2 12 inch 3xl subs and there not loud to me, the box is 2.0 cubic feet per chamber. I hear great things about them so my question is will they get louder after they break in or will i need to put them in a bigger box thanks.
