How Much Deadener is Needed to do...

a whole sedan? I want to deaden my 94 Accord, the doors, floor, and trunk. I have NO idea of how much to get. Most people I've talked to used multiple layers of sound deadener so I think I may do 2 if it is not too expensive. Is around 150 sq ft enough to do the doors, floor and trunk TWICE?

I would think u may need 175-200. I know 50 is usually enough for most trunks.

I'm using about 250sq feet in my Civic hb. That's for 3 layers.
