Alright, this may be a question already asked, but I looked and I didn't come across anything. I put my stereo into a 96 Mercury Mystique. I can't roll up the windows right now, 'cause I'm waiting on a new switch, and motors for the windows. Is it louder, SPL wise for a car to have all windows open, or all shut besides the drivers window? It gets pretty loud with all windows down, and driver's door open, and flexes everything pretty well, but I think it can be louder with everything shut.
