Sunday and Monday afternoon I spent some time working on sound deadening KITT's roof. I know there is a lot of debate among third gen enthusiasts as to whether this is worth it on a t-top car. I recorded a before and after video to answer just that (as much for myself as for everyone else).
On two separate occasions when I spoke at length with Rick from RAAMaudio he stressed that covering or sealing up all the access holes in the framework of the car will go a long way to cut down the resonance. I took this to heart and along with covering a little more than 80% of the actual roof top (area behind t-tops), I sealed and/or covered every access hole I could find.
