I have an ES350 and decided to insulate all the car: 4 doors and trunk with Roxul Safe and Sound (don't worry, i put the wool inside plastic cover before fitting it to the car, i did that before on my previous car):

The car is now dead silent but, i notice that the rear deck, which is not insulated yet is rattling like crazy.

I wonder if i should have left the trunk air vent (located on the driver side hidden behind the trim) unobstructed because i put the wool all over the inside of the trunk trim ?

Is it possible that i made the car too much air tight ? Of course, my next step is to insulate the all rear deck, but i don't know how to remove the rear seats.

Before insulation, all 4 doors rattle a little bit and so is the rear deck.

Pics would definitely us understand exactly what/how you did.

On the first picture, we can see the air vent that lead to the bottom of the car.

I install blocks of wool all around it and over the entire trunk wall.

I don't think that insulating the doors would cause any problems since it has no air vents.

When you knock on the outside panel, it doesn't resonate like thin metal since and the sound is very well kept inside the car.

I can test my theory by maybe opening the trunk lid and play some hard bass or open the ski pass-thru to let air circulate.
