Finished up second FI-Q 12" but thought it would have more

Just finished getting the new dual sealed box in and have been playing it now for a while with the second FI-Q 12". I guess I am using the full 2000W of the amp now and although sealed I think this is about as loud as I want to go for everyday. Just thought adding the second with even more power would be night and day but it isn't. I know it usually takes listening time to really feel it out. They make the hairs on my arm shake and I am shocked the stock Honda alternator is keeping up. I do have a cap and the big battery which helped a whole bunch but amazed still.

 
How big of box for one ported? I can't fit much more than what I have in the trunk without having zero space for anything. I need to deaden the lid and stuff since it rattles like crazy.
