    That's a tough one, dynamat works well if you want to tear out the interior and put it down. Outside of that, your at the mercy of the vehicle design.

    I removed the interior door panels and stuffed fiberglass in them. This made quite a difference. I also began stuffing fiberglass under all the plastic panels in the back of the car. I rode in the back seat when when my son was driving once and there is more noise coming into the cabin from the rear end than from the front. I plan to stuff more fiberglass underneath panels in the trunk and back seat.

    I also hear the dynamat works well. I want to try some of it underneath the car. I am not sure it will hold up well to the elements down there but I may try it to see if it even works to deaden sound from the floor area.

    I had a lot of success with Reckhorn sound deadening material. It used to be on Amazon Prime, but doesn't seem to be right now: https://www.amazon.com/Reckhorn-Self...words=reckhorn

    It's basically a cheaper Dynamat. I put it inside my doors, and it had a very noticeable effect on road noise.

    I did the floor, doors and rear wall in my 2008 Tacoma. So far I've only done the trunk in my WRX. Once I'm out of my apartment and back in a house I plan on doing the same. I use Noico deadening products.

    Sound dampening materials, and a well executed mindful install will make a world of difference.

    I put FatMat in the doors while upgrading the speakers.
    Don't have actual sound measurement data, but I feel it was worth the effort installing it.

    #1 improvement I've done is placing foam adhesive on all contact points of the A-pillars. I'll see if I can dig up some pictures.

    Cheap, easy, and you'll definitely hear a benefit. Like I said, I placed the foam on the plastic spline contact points too.


    Edit 2: Maybe I missed the OP's question......Do you mean road noise? Or noises from the interior?
