yeah i guess i know i'm getting a boost at that center where excursion peaks i thought it had to be the enclosure but i was told cabin gain

How did you find this freq? If you ran a sweep on a TL and that was what the car peaks at, You cant change that.

Edit: You can build a different box and try to get a different Peak freq.

someone else who knows a little more about this should chime in.

i don't have a TL but i ran a sweep and found the peak with a cheap spl meter, i know the peak is there, cause i can hear it audibly and it makes the cone of the sub freak out

If the "cone is freaking out" then it's an issue with your box or the tuning of you amps, not the car.

yeah thats what i thought, if it were a problem with the cars acoustics, then it wouldn't effect the cone
