I did this to my NX doors 2 weekends ago, except I didn't put an MDF panel over the large holes. I just cut a really long piece of the deadener and stretched it across. I was SHOCKED at how large of a difference it really made. I used 6" aluminum roofing flashing from Lowe's! Hah, same concept. Worked wonders. Half the price. Eventually I am going to rust proof the rear of the NX and cover the entire interior in it.
This is what I have, but in 5.25". I love love love them. Again, the sound damper I put on the door really brought these to life. Covering up all of the holes in the door panel really made all the difference.
