In the middle of putting sound deadener in as many places inthe 2020 Classic back seat area. While doing the floor I by chance took out the storage compartments. To my amazement there was the bare ground beneath them, Obviously a source of road noise. So I took the compartment out fully and although it had some minor insulation on the outside ( road side area) I put sound deadener and decoupler on the inside and chucked the plastic bin away. Put deadener on the flloopr over the hump and completed the other bin the same. Then on the divider ridge put deradener and decoupler in all the depressions and put the carpet back over everything. My dog platform has an extra 2 inch dense foam attached to the 1/2 plywaood cover with heavy black vinyl. The firewall has deadener,decoupler and the same padded bench upright.
What a difference !
