Recommended Posts

So im changing builds im going to do a 18 in a aero ported box in the trunk of my 98 grand prix. Im going to put sub closer to rear seats & port there also and seal off half the box to the cabin like I have now the 18 will be firing upwards.

Does anyone have any tips on how to build strong box inside of a trunk?

Box is 3.5cu tuned at 31.8hz sealed off from the trunk. 14sqft of Dynamat on the Rear deck top & bottom. Soon to be more for doors/roof. Gets low & loud

Buy a kreg jig, pre drill and assemble outside of trunk. The kregbnig is worth its weight in gold to me.

Obama has a law he's trying to pass right now, trying to ban Leo for being a threat to children everywhere.



EDIT: Not in a JP kind of way.

I thought I was going to die from all the jizz filling my ears.
