"sound dish", do you mean speaker baffles? From my research I hear those are horrible to get and muffle the sound output because car mids are made to be mounted with a larger area of space, a sealed enclosure which is why I sealed the holes in the door. Those baffles act like a tiny enclosure and degrade the sound, from my understanding anyways. I was going to actually get them till I started reading online people saying they are bad, so I just re-used the stock baffle that only covers the top of the speaker in the back mainly to keep water off it.
But I did see alot of people mounted egg crate foam on the inside of the door right in back of the mids for sound deflection, which scott just happened to send me as packing material with the struts he shipped. So I will be mounting that in my doors now.
I used Dow window and door expandable spray foam along the bottom of the doors, where the sections of metal meet. I did have to do alot of work after to shave down the foam it grew so much in order to allow any water that got in the door (and alot does) to flow to the sides and out the two holes at the bottom. I used a long screw driver to make passage ways down to the openings in the bottom.
And the reason I know water gets in the doors is i washed my car one night and in the morning opened the back door where I already had the door panel off and water came pouring out one of the holes where the panel fasteners goes in. It must get past the window gaskets and go right in. If I didnt catch on to this because of that I bet my whole door would be filled up with water after a really good rain storm because I sealed them so good with the foam and peel n stick membrane.
And what I do now is drive down the highway and listen for road noise, and since I did the doors im hearing it mostly from below the rear seat and at the front kick panels. So i will be doing those areas next. I dont notice anything from the roof just yet, but who knows once i do the areas listed above.
