I have a ton of flex on my back hatch window on my 07 escape with My btl, especially right around 28-32 it literally breathes and i feel i lose a ton of SPL from it flexing so much.
Would putting a layer of audio technix 80 mill eliminate that at all?
Is there something else you would recommend for a back window that leaks sound like that?
If i were to seal up the back window (and possibly back side windows) with 3/4 mdf wood, would that make my car technically a wall for competition purposes? (i dont want to be in that division for what its worth)
