Sound deadening Question...

How many square feet of sound deadening material will I need to do the Driver and Passenger doors on my 06 Access Cab?

Also does it make any difference what Brand I use, Dynamat, Hushmat, Fatmat, etc?

 

Basic coverage for the front doors is going to be about 6 square feet each, but you can put more to quiet things up even more. Check out one of the sound deadening project threads on here, there are a few good ones that explain what kind of coverage you should go for.

As for the brand, pick something reputable. There's nothing worse than sound deadener mat that separates from its foil backing and/or turns into goop inside of your door. DynaMat is always a safe bet, though more expensive than most. There are other good brands out there. Check out STP Atlantic, too.

 

I just ordered 12 sq. ft. GTMAT from Amazon, it has a lot of great reviews. Dynamat has worked great in the past, but it's so expensive for what it is, IMO. Going with the GTMAT for my install coming up, most likely next weekend. I can keep you posted.

I'm leaning towards putting 4 sq. ft. in each front door, and 2 sq. ft. on each rear. Since I'm throwing in some sweet Focal 6x9 components up front, I want to maximize the low end of those (not going to install a sub, at least at the moment) and am really not that concerned with the rear fill. Just putting some inexpensive Pioneer 3 way 6 1/2s there.

Excellent SilverComa,,,,, I'll be following your thread with interest!
I agree that the DYNAMAT seems a bit excessively priced.
I recently got in on a group Purchase of ShokMat via Manethon, here on the forum.
Gonna give his stuff a try..... I got enough that I should be able to do Driver & Passenger doors and still have a bit left over. Ill post my results when I get done doing the deed.

 

Follow up: I ended up putting the same amount on all 4 doors, approximately 2.5 ft per door (had a couple sq. ft. left over). I basically cut strips and patches/squares and places on all flat surfaces that made sense. I only peeled off the edges of the plastic sheet enough to put big patches of deadening under it. Sound deadener is only meant to absorb sound waves and basically make things heavier. It doesn't affect the sound to apply in a patch work manner as I've done. You're more than welcome to line the entire door with one sheet, but I genuinely think that is a waste of time and material.

I put about the same amount right behind the speaker on the inside of the sheet metal and down the door a little, as I did on the inner stamped metal framework. Something I think made a big difference was cutting strips to go directly behind the mounted 6x9's, so sound waves are immediately dampened.

Road noise is down a little bit, but most of the noise in vehicles comes from the windshield, top of cab, and floor from my experience. The doors have a great "thunk" now.

I used a heat gun directly to the sheet metal (not the material) as it was a cold weekend. Just got it hot enough to be warm/hot to the touch. I'm sure if it was summer (or above 75) this wouldn't be necessary.

I'm pleased with the results, I have no rattling in my doors AT ALL due to bass and I'm running amped up 6x9's (50w RMS) in my front doors. The midbass sounds fantastic and I ALMOST don't need a sub. But we all know how that goes...once you change your speakers you want a sub even more!

 

Thanks for the Rep,

Op, Pm me and we can chat about what you want to do and your over all goal.

 

Anybody have any thoughts on an Ensolite alternative? RAAMAUDIO apparently doesn't ship to Canada.
