Hiss from under the rear seats

[cbecra1]

What could cause a hissing type sound under moderate to heavy acceleration that comes from the rear seat area? Is that an e-torque thing.? I have the back seats flipped up for the first time which is why i think i heard it...just curious what it could be. It feels fine, just makes that hiss.

Also as it relates to sounds, i also get a quick high pitch sqeal only when restarting the truck after it had recently been driven (cold starts no issue) Its inverse to normal belt issues that resolve when warmed up. Is this another etorque type characteristic related to generator mechanism?

There are a few threads on here about noise coming from the back of the cab. Seems to mostly be related to the air vent opening behind the back seats. People have constructed some pretty interesting things to reduce the air vent noise. Supposedly you can check this by pressing the recirculate inside air only button on the dash to see if the noise goes away. Mopar also used to install a horizontal seal on the bottom between the bed and the cab however they stopped installing that in Sept. '18. Many people have installed it as aftermarket part and it has greatly reduced the road noise. I do not have that piece on my truck but also for whatever reason the noise seems not so bad. Just some things to think about.
