sunroof

Pretty straight forward honestly. Ill be pushing 2 12s on around 1600 watts. Is this enough to have to worry about any damage or leaks? My brain says the thing to do would be sound deaden the sunroof with as many layers as i can fit and then slide the cover closed and hopefully never think about...

Hey guys, I drive a '97 Acura Integra. Let's just say the lows make the sunroof go nuts. What's the best way to reduce the flex/noise without removing the actual sunroof and mechanism?
