What do you guys use as sound proofing the interior of your cars? Looking into re-doing the interior on the 5 and need some for the door cards

I have some Dynamat stuff that I am going to do my door cards with, you can buy a kit to do both doors from places like caraudiodirect etc.

Just looked at Dynamat and they do the "XTREME CUSTOM SHEET" (457mm x 812mm) for £18.49. Probably will buy two in case!
