Meh DD's are a bit of a tight squeeze in the Alero. I have a Pioneer AVH-X5500BHS and it fit but I had to notch the trim bezel for the flip out and cut some dash supports for depth. Your best bet is a single din say the JVC arsenal 75 series. It has everything mine has but the back up camera and dvd options. You CAN put a DD in it but more than likely you will have to do some fitting.
