Hey boys im sure yall have done this but i need help with it i want to put speakers in the doors of my 90mm but i want the windows to work rite and what would be the best size to go with?

Look in ur other topic I posted reply to this

Here's a pic, didnt want to take all the stuff off and pull the door panel off, but you can figure it out from the pic. There is an access hole right there, trim it a little rounder to fit a 6 1/2" or 6 3/4" speaker in there, then cut a hole in your door panel.
