Need help on making my 99 blazer back glass quieter

[MerkConvoy501]

So i have 2 kenwood excelon twelves on a zx750.1 in a 4.3@33 hz box. My back glass makes alot of noise. I have a box already built for four twelves and im wondering what other people have done to help rattle or whatever from the back glass.

Replace the rubber seals with a newer seal, Can always take some flexable caulk and seal it shut too.. Will have to replace the seal if you ever want to use the glass again.

If you make the window stop rattling, you will stop losing air pressure. as far as sq eh, prolly not a ton but some.

Like with my car, My doors flex around the seals about 1/4-1/2" so I'm losing a ton of air because of that. Can I fix it? prolly but its not worth the cost or resealing the seals and adding a ton of weight to the doors. I have 3 layers of deadner on it now. Inside and Outside. "not the car door but inside the panel and outside where the panel sits"

You can try adding washers to the latch bolts so the glass has a tighter fit when closed

Not much you can do. Can add weatherstripping to the strip that's there already.
