what were the specs suppose to be? 2.0 cu. ft. tuned @ 34 hz? will this box be louder than what i have now?

It was made to be 2 cubic foot tuned to 36Hz. Like I said before, it is a little larger to account for driver and bracing displacement. If you were to add those two then you would get very close to the 2 cubic foot @ 36Hz. I don't know if it will be louder then what you have now or not. Do you know the specs of your prefab enclosure? I would guess that this design would sound better overall but I don't know if it will be louder. Prefab enclosures are typically tuned pretty high (higher then 36Hz) so it may not be quite as loud at some frequencies. I would bet that it would give you better overall sound while still being loud though. Without the prefab specs there is no way for me to say for sure.

here are the specs on the box i have now: Port tuned @ 38 Hz (that is what is said on the description) 3/4" thick MDF (almost an inch) (W x H x D): 19.25" x 14.25" x 16.25" im not happy with my bass. its not loud enough lol. do you recommend any sub or subs?

If you are using an enclosure tuned that high then you probably won't be getting much louder sound and still have a good daily driver. If loudness is your goal then look into AudioQue or FI Car Audio. They have some good subs that will get loud and are priced well.

what about 2 kenwood kfc-w3012's in a ported box?
