too much dynamat?

I have an F150 Supercrew. YesterdayI put a layer of Dynamat on the inside of the door outer skin, and then a layer to completely sheet the inside skin and covering all the holes in the door frame. I did this to both the front and back doors. My recording engineer soon said he thinks this might over-deaden the doors and kill the sound when I put in the sound system. I won't have the new sound system for a week or so to try it out and see. So I thought I would ask here. Is it a problem the way I am doing it, or should I go back and cut out the holes on the inner door frame and reinstall the sheet of factory moisture barrier? Thanks!

LOL. No man, you are ok. The dynamat will prevent rattling and flexing of the panels. This WILL give you a better sound system. I don't understand how your engineer thinks that road noise and door panel flexing makes a better sounding system. Dynamat: 1. Doors 2. Trunk 3. Floors 4. Hook and headlining.

Thanks for the fast reply. I think he was mostly thinking I should cut out the holes on the inner door to allow any sound from the back side of the speakers to "get out". But If I am loosing that much sound behind the speakers, I would think I need speaker boxes to fix that. But I think I will keep it the wya I have it now. Thanks Again!

if your statement were true, ask your engineer why we dedicate so much time and effort building and designing speaker enclosures. The main purpose of an enclosure is to separate the front and rear sound waves of the speaker. do this simple test. remove the one of the speaker from the door panel and play your favorite song with the speaker out of the door panel. Then put it in the door panel and listen to what sounds better. Its a no brainer.

The only real thing dynamat does is lower the noise floor, so that road noise and panel rattling doesn't interfere with your music. It just adds weight to the panels so it takes more for them to vibrate. <<<< that's a good thing. I don't think you could really over dynamat. So your effort should be worth it!!!MECP Advanced

Make your life easier and buy a DMM.

So how does the speakers sound with all the extra sound deadening? Did it make a difference or did you remove the extra materials?

You can never have too much power, and you can never have too much Dynamat.  The Dynamat rep told me that one.

Sure as long as you already have too much money I imagine with any type of insulation / sound deadening material you reach a point of diminishing returns?

In short, the added Dynamat made a HUGE difference and the system sounds great.  Even my wife commented that if we ever get another truck, the first thing we do is Dynamt it!

I too was a skeptic but that's fantastic to "hear"! My interior is currently going through an overhaul as I am building a custom console and will be adding dynamat to the doors, floors, and possibly the back wall too. Thanks!
