Door sound deadening opinions
I'm putting 6.5" separates into the car and the tweets are going in the factory dash location and the 6.5's into the doors. Already have it fabbed (tight fit with power windows) but will work without spacers.
These doors are "tin" and "hollow" sounding.
So aside from the rattle fixes, I bought the "dynamat" similar from Home Depot. Looks easy enough to apply to the inner door surface but the back of the outer skin seems hard to reach.
Some videos have guys spraying "flex seal" heavy rubber coating behind the outer skin and then using mat only on the inner door panel.
Some put mat on everything even the backside of the door cards.
I don't need it to be perfect, just 95% good. (It's a convertible). Want the door speaker to be able to do its thing.
Looking for thoughts/opinions.

Re: Door sound deadening opinions
What do they offer now? It's been a while and the last I heard folks were buying the "peel and seal" stuff and there is much better out there for a similar price. Not sure what you bought but here's a pretty good comparison video of the Peel and Seal verses the least expensive "real" butyl dampener that I know of.
Plus, the Noico comes in sheets that makes it easier to cover the hard to get to outer door skin. I always cover the inner and outer skin totally with the dampener. If i know of areas on the door card that was vibrating before, I'll throw a little at it as well. In my G8 GT I had to cover most of the door card, in my old Thunderbird I didn't use any dampener on the door card just some sheets of closed cell foam. I also put about an 8x8 sheet of closed cell foam on the outside door skin directly behind the speaker to resist sound reflection. Doing so really does make a huge improvement in midbass output.

Re: Door sound deadening opinions
Dynamat and the like are vibration dampening, not sound dampening.

I use mass loaded vinyl for sound deadening, and in my diesel I am going to use some lead sheet to dampen the noise even more.
