I had read the other post and would like to give someone an idea to keep all that bass inside your vehicle.

I saw it at a SPL event this year,,,

Duct tape all you windows and doors shut [img]tongue.gif[/img] . The guy I saw actually though it was going to make a differance, so why not try it [img]graemlins/freak.gif[/img] .

It just makes it tough when you want to get in and out easily [img]graemlins/thumb.gif[/img]

It was one of the most laughable things I have seen in years.

 

From my understanding, it will keep air from leaking out the window and door seals, and they don't allow it in street class.

 

But then again that answer was obvious, what can't duct tape be used for?

 

you gotta remember that going thru all that just make the air come out of the airvents, the heater vents, the keyhole, and any where else ion the firewall that air can escape thru. even completely sealing it still make everything shake more(because it's not solid), then that brings the number down. so you fix one problem and another comes into play to bring your number down.
