are you going to do the full job like hokierunner? i'm thinking about a partial job to save on weight...

it would be interesting to get a total added weight from you.

Yes...planning on the total. I'll add up the weight as I get all the stuff this week.

Wow! Not sure how I missed this post before, but that is an impressive job! If there were a Hall of fame for mods here that would get my vote.

Great job Hokie! I like your choice of speakers & amps I do hope though you don't have a door lock actuator go like I did. You'll have to rip off all the deadening to get inside the frame.

It's the reason why I didn't make the doors completely sealed like you. It's great for midbass & sound resisitance. But crap for door access.

Anyway, props to the hard work. I know how your back felt after all that!

Awesome write up. Very Detailed. But...

What did you use on the tailgate? I'm assuming FatMat?

I have a sub and the only thing that I ever hear rattle is the rear window, license plate, and rear panel.

Also, DynaMat suggests that their material blocks heat? Does FatMat and/or mastic peel & seal do this? That would be awesome because its about to be a hot ass summer in TX.

I agree, covering 100% is a waste but it his money- his choice. he did an awesome job at that. I brt it`s not even close to 1000lb weight, maybe 100.
5db noicereduction is great now it`s almost 4 times quieter, I can only imagine. I`d use different sound deadener. raamat or second skin if money were no object. as it always is I`m using elemental design e-dead

what speakers did you put in back door if anything? if so, how did wired them stock or pulled new wires?

Can I ask why you put the peel and seal over the rubber? And does the P&S smell like asphalt?

peel and seal is asphalt, it stinks but it get job done.

Good luck with the install! Can't wait to see how you set those amps up but I'm sure it'll perform great.

I still have yet to deaden the tailgate. I'll be doing that soon and will use the FatMat just like on the doors. I've worked with FatMat and Dynamat and I notice very little difference. You just pay for the name with DynaMat, IMO. The FatMat (any dense material for that matter) should help insulate the vehicle.

I used the same speakers front and back. Ran new wires everywhere. The entire OEM setup was removed or bypassed.

I used peel and seal on the rubber to seal off the edges. I also bought more sound deadener than I needed so I figured I might as well use it. As someone mentioned above: peel and seal is asphalt and smells like it! Working in 90+ degree weather for 4 days burned off all that smell by the time I got back to re-assembly so it worked out fine. No hint of asphalt smell since then.

As has been addressed - the coverage was definitely overkill but for the price I paid, I have no regrets.

I just finished deadening my rear hatchback door. I used FatMat and applied generously, because like someone else mentioned, all I heard rattle with my system was the rear door.
When others get around to doing this on their own vehicles, make sure you disconnect the negative post from the battery before unplugging any wiring harnesses. Otherwise, you'll find that your electronic door handle and automatic closer won't work anymore, until they're reset.

Unlike HokieRunner, I didn't replace the plastic water shield with ABS plastic sheeting...it's just too expensive for the minor purpose it serves. Even Amazon and Ebay were about $10-12 (shipped) for one 12"x12" square of 1/8" ABS plastic sheeting. Could not find any sheets locally either. When I come across some material that I feel will work, I'll replace the water shield and do like HokieRunner did to his 4 passenger doors.

Here's some pictures. I also removed the door handle assembly on the exterior (right above the license plate)...the thing with the logo and the license plate lights...and applied FatMat directly on the body of the car where that plastic assembly goes, but I didn't get a picture.

In the picture above, you can see I removed the black plate on the right side of the "Before" picture, and let it hang by the wires. That allowed me to get behind it and apply FatMat on the inside part of the door. Behind the white box on the left side of the picture (which is where your manual release levers are located, btw), I applied two layers. It's the central area of the overall door.

I also decided to line the majority of the inside of the plastic trim cover:



Effects after Installation
After installing, I noticed I was hearing new rattles in other places. Those new ones will be gone as I slowly cover the entire car. From the outside, bass is definitely quieter, and the loudest** thing rattling with the window rolled all the way up is the glass itself hitting vibrating metal. The metal that the window is contacting is in a very tight location which will make it hard to install FatMat.
The trunk feels solid when shutting the door. No more of that hollow shaking sound when closing. I can't wait until the rest of my car gives a nice solid thud.

**I have two Kicker Comp VR 12" powered by a Kenwood 9105D 1800W Mono amp. There is a lot of bass for the rear door to handle, and I'm not going to lie and say all the rattles in the rear door are gone. The window is the loudest source of rattling ONLY when it is rolled all the way up. I have found that rolling the window 1/4 the way down eliminates the glass hitting the metal and the horrible rattle noise that it makes. Even then, with the glass not contacting any metal, the rattling is there, but it is so faint. With the window rolled down, the loudest rattle is probably...the rear window wiper blade. Besides the rear wiper blade, there are some rattles coming from both of the rear quarter panels, but I'll get to those at another time.

The rear door has so many objects in the way. It kind of sucked to do, and required several small pieces. Overall, it took me about 9 hours (cleaning, applying, testing).


As for the license plate, I put a piece of sticky back foam that I bought from Michael's (arts and crafts store). It's cheap, ~ $1 for a 9"x12", perfect to make a license plate cutout from. There is absolutely NO rattling from the license plate, even at times when I can see the plate oscillating. The one piece stuck great for about 6 months, and it's just now starting to peel at the bottom edge. Alternatively, you could apply FatMat, but I think the aluminum backing on the FatMat might cause a small noise. By the way, I don't use any license plate frames. They rattle like crazy.

Like I said above, the rear panel itself doesn't rattle too much. The loudest rattle is the glass itself, but ONLY when it's rolled up. When rolled all the way up, from the outside it sounds like a jackhammer nailing a steel beam. When rolled 1/4 of the way down, the jackhammer (glass on metal) sound is gone, and there's only slight panel vibration now.

Quote from FatMat:
"Our FatMat and RattleTrap products are constructed from premium acoustical sound dampening material and space age heat shielding material. With proper installation dramatic noise reductions as well as tremendous bass gains can be accomplished."

While the panels with FatMat installed themselves may not allow heat to pass through as much as before, it will not make your car cooler when left out in the sun. Even with tint on your windows, the sun's energy passes through your glass and is absorbed by materials inside the car. Theoretically, your seats can't be hotter than the air or any other material inside your car, which means that everything inside the car will try to balance out so it reaches thermal equilibrium. No matter what you do to your car, if left long enough in the sun, it WILL eventually surpass the temperature outside. The only thing any insulating material companies can claim is that they can reduce the time it takes to for temperature to change. I think I'm right there with ya with the heat in Las Vegas, NV, if not worse!

Anyone know what cargo barrier this is?

Tailgate window rattles when its all the way up on mines too, i got 2 15s, sometime u hear like a clap on short bass notes, but on high excursion it produce some rattle, but its not loud and nasty. I need to do my rear panels to complete my dynamat install. Best thing i did, more volume and clearer sounding music.
