Can anyone tell me how much dynamat I would need in my trunk for a 14 ilx.. and also I'm looking for anyone's opinion on speakers.. I currently have a jl sub but I want to get new speakers inside the car all around. And unfortunately I don't know much about that.

 

I used 14 square feet of 80 mil Noico on the rear deck (top & bottom) and the trunk lid of my 2012 TSX.
