Im thinking about dynamatting the whole door and was wondering if it will be a big enough difference to worth the time and money? If so, would dynamatting the door panel be helpful too? any tips on certain areas that would benefit the most? or should I just slap the whole thing on the door?

 

What is it are you planning on accomplishing? Dynamat will not reduce road noise much, but it should help rattling and vibrating doors caused by your speakers. It will also give you more bass/midbass & a "truer" sound without all that resonation.

Advice: Apply as much as you can possibly apply. At least one layer inside the door cavity, and one more on the inside metal part that faces the door panel. You can go all out by putting on multiple layers. Also use clear silicone on anything that rattles and doesn't need to move.
