with the windows up and the plugs in the floor area, its not really noisy at all, other then the wind noise from the lack of aerodynamics the jeep has but i don;t know. when i compare my no carpet hard top and full metal doors to the wife's old fully carpeted yj with hard top and full metal doors, it is a heck of a different amount on noise. hers, the kids would easily fall asleep in on long trips, mine..... they fall asleep but not so easily. they like it better since i moved the seat back and up so i think that was the main issue. i don;t think noise is really a problem because when the windows are up and the top is on, i ride with the radio very low and can talk on the cell and hear it easily.
