on half power and being his first time it did 148.3@41hz sealed in the kick Why was it sealed in the kick? O_o thats where they put it we got screwed by USAC that day the truck was built for BS and they made us run SPL. O well it happens. That still doesn't explain why it was sealed in the kick? If it's in the kick the door/window can be open. idk we entered Local class StreetBeat but when we ran we were told SPL only like i said it was messed up but still had fun. And do you mean SB, street beat? If that's what you wanted you could have entered it, no one was stopping you.
