in my cavy i had a 15" Incriminator DP, on a 1501d at .5 ohm, and i hit a 143db legal on the dash with the windows up. i had it in a 4ft^3 after port displacement box with 78.75in^2 of port area tuned to 32hz. and i hit that at around 43hz test tone. so there's not a chance you're hitting 40's with a 12 sealed and won't do 50's ported man. get 2 15's to even attempt.Well let's see I have an Incriminator Audio Death Penalty with 1000 watts rms only on a sealed box. All that in my F-Body....low 140's. When I get my ported box built,(3 cubes, 50 sq in of port) I should be in the high 40's and possibly really low 50's.
EDIT: I forgot to mention, sub and port will be firing up directly into back glass.
