MR2NR, what do you have to recommend and the price ?

While in the subject, any of you guys ever did the inside of the door as in the reverse side of the painted side or just the side behind the door panel ?

 

^I did all sides accept the painted one on my doors.

 

I've applied the fatmat on both sides of the door. Use good/new sheets on the facing side of the door and whatever left to cover surfaces inside the door. Start with the spot where the woofer's waves would hit the metal first.
