dynamat on doors

Impact9

I covered my 04 F150 supercrew front doors with Dynamat extreme but the door kits didn't have enough to do the big holes in the doors. I did dynamat what I could reach of the inside of the door directly behind the speakers. I ordered 2 more door kits from ebay at a good price to do my back doors and back of the cab. Road noise is pretty quite in this truck since it was built with this fancy "quite steel". Only reason I am doing this is to improve my speakers performance and maybe make the quite silent.

So I was wondering if covering those big access holes in the doors is worth it? Will it improve the performance of the speakers? Would covering the hole with plywood be a better choice just to get more of a sealed box effect? There's still several 1x1" holes that I can't cover as my door panel hangs on the door and then a few screws secure it. I'm hoping someone can shine some light on this for me. I can post pictures if need be.

Oh tomorrow i'll have Polk MMC6500 in the front and MMC650 in the rear with plenty of "amplifryer" power :cool: .

itll make a substantial difference in bass response an sq. Itll actually make it a true infinite baffle setup. My back doors are done that way(havent finished my front doors yet) and 3 people have asked me if i had 6x9s in the back...I have a couple of 4x6s back there...

Ok what would be better though, rigid plywood, lexan (plexiglass) or more dynamat extreme? I got plenty of all.

I used Dynamat Extreme on one car and SecondSkin on the other. Completely covering the doors, as well as the areas you can reach through the holes will make a substantial difference in your music....

Just Dynamat the entire door and cover all the holes. Thats the best way.

thats the only downer i have right now, i dont have any dynomat and my entire Interior rattles when my 6x9's punch...i have the bass at -7 on my deck cause i was told i had bad distortion "all i hear is rattle, not distortion"

what all will i need to dynomat so my interior wont rattle as bad?

BTW I have MMC6500's in my doors and MMC690's on the rear deck in a 2004 Hyundai Sonata!

Go to your local shop and buy as much Dynamat as you can afford.

First off, Dynamat the hell out of wherever your speakers are located and the surrounding areas.

Then if you still have rattles and buzzes its simply a matter of playing a bass heavy CD and then tracking them down one by one.

much cheaper than dynamat and a better alternative IMO

I totally agree Cody. I also recommend their rattle pad, it works very well behind vibrating plastic panels. I used both the rattle pad and damplifier on my front doors. I plan on doing the same on the rear doors and reard deck area.
