Anyone deaden a 2016 with Jbl system?

I got my first taco a couple weeks ago. It has the Jbl system in it which is okay but isn't as good as it should be for the price. Besides the funky sound processing, I think the sound is pretty good. The biggest problem I have is the frequency that the bass level changes. The mid bass is too much compared to the sub bass and the doors resonate and make it even louder.

So has anyone deadened their 2016 without changing the speakers? I may add subs at some point but that is a couple years down the road.

 

I was planning on doing this to my truck when it gets here. This is one of the first things I did to my 2nd gen and it was night an day better.

 

That is enough to convince me to try it, I can't stand the buzz anymore when I crank it up!

 

Here is a video of someone deadening the doors on a 2016. Thought you might find this interesting.
