What are those vents on the back of the cab for?
I'm in the process of installing my upgraded sound system in my truck. In order to be able to fit my subs behind my back cc seat, I have to leave that back "cloth" panel out of the truck. So that leaves those two black air vents exposed to the cab, which causes more road noise in the cab. I was looking at taping over them to help reduce some of the added noise, but was curious what they are even for?

Don't quote me but I think they help ease preasure when you slam the doors with all the windows up. With out them you have to REALY slam your doors or crack a window down a little to shut the door normal.

Yes, you might try surrounding them with foam or felt. Basically anything that will pass air but block some sound.

Tape over them, then slam your door with you sitting in the truck. It'll hurt.

When I dynamatted my truck, I went right over these and then went back and cut a slot through the middle of both, it seems to be quieter and cabin pressure isnt a problem
