I used electrician duct seal putty from lowes or home depot, to deaden the plastic.
And used a combination of duct seal and polyfill inside the pods
Depending on the way you built your pillar pod, you may want to look at deflex pads

Will the duct putty melt and run if its really hot?

Mine are glassed, some bondo behind that, followed by modeling clay, cld where needed, and polyfill behind the driver.

Ok so I am in the middle of glassing my A-pillars. I am installing a 3inch mid and tweet (focal krx3). How should the plastic panel and structural portion of the a pillar be treated? I was looking at a few things from parts express... Thanks

Looks like CCF to me

That stuff is open cell. I'm using it on my dash in place of a dash mat, covered in grill cloth.
