whats good to insulate the back seat form the trunk????

Why, if I may ask? Sound, or heat?

I think most G-body's rear seats have like a triangular metal frame behind the rear seat.

My floor, doors and front firewall is insulated with dynamat. Floor also has a layer of regular fiberglass padding, then carpet padding, then the carpet. I don't have my rear seats insulated because my subwoofers are in the trunk, and I don't want to inhibit any sound from entering the cabin.
