But, I wonder if you might have changed the X-over FQ on the amp or other crossover device when you reinstalled the equipment. If the sub is crossed over at 40hz, it might have the effect you are describing. (I don't know if your head unit has a built in sub crossover but if it does, I would check that too. -maybe it defaults to some setting you don’t want.)
Also, a ported box that is incorrectly tuned will do this also.
Sorry if any of this has already been covered.

na man. I just checked the crossover and its set at 85, which i believe is normal.
i looked at the sub when it hits and it pushes out, so i'm sure its not the polarity. next step (which i will try tonight) will be to take the sub out and check for any leaks. anything in particular to use for sealing up holes in a box?
