Sound Deadening Project (picture heavy)

[Skidmarcx]

That's a clean install! I miss my Slash amps they sounded better to me... but the power/size of an HD is hard to beat and they still sound good for a class D amp

Thanks, I loved it but I was over it, and I lost interest in the car as a whole. I loved how everything sounded for sure. and yes the HD's are a hell of a amp for what they are.

Dude, I had no idea that your sound system was so extensive. You are gonna have to show me that sucker once you get it up and running again!

LOL yea man that's one of the reasons I did the 4WD swap versus selling and buying one

Skid, great writeup!!!!

I had a few questions for you based upon your selection of materials. I am about to rip out my interior and mirror your project.

Materials used
- 45^2 ft Dampifier Pro B-Stock (Constraint Layer Damper)
- 90^2 ft Overkill (1/8" Closed Cell Foam)
- 45^2 ft Luxury Liner (Mass Loaded Vinyl)
- 20^2 ft 3M Thinsulate (Acoustic Barrier)

Overkill vs Overkill Pro. In your experience, is it worth stepping up to Overkill Pro? Especially with all the other deadening materials used. Is there a value add?

Luxury Liner vs. Luxury Liner Pro. Same question. Worth the extra money to step up to pro?

Greater than 25% coverage for CLD? I have about 70 sqft of dynamat xtreme coming in the mail. I saw that you were using CLD sparingly in the cargo area and across the floor. Any benefit for increasing CLD coverage to 50-75%?

I'm at a point right now where spending a few more bucks for better materials isn't that big of a deal, especially when compared the amount of labor involved and the base amount invested. But then again, if there's only a minimal difference, no reason to overspend.

Thanks for all your help in advance!

I appreciate it man... I chose to use Overkill because the door panels don't have much room to spare, so it gets tight with MLV layered on top... Same with Luxury Liner I wasn't sure how much trouble it would be to lay down since it already has the CCF layer attached. After doing it I can tell you that Luxury Liner Pro will work fine on the floor, but will be tough in the door panels. I didn't use MLV on the tailgate for two reasons... Not much noise comes through there and I don't want to weigh it down. For Dynamat (CLD) you don't need a tremendous amount because it won't block noise it only subdues rattles and vibration, so basically cut up small tiles and add as much as it takes to quiet down a specific area. The majority of your noise control will come from the CCF and MLV layers since they actually block sound... So full coverage on the floor and door panels helps a lot. I used 3M Thinsulate on the roof because I'm not too concerned about noise coming from above, but I am concerned with the amount of heat that penetrates from above.

Just noticed you were in Phoenix. I guess heat would definitely be an issue for you. Let me tell you about our 75 degree summer days in Portland!

Thanks again for the info. I might actually invest in a bit more sound deadening and resonance modifying CLD's on my roof. My roofrack howls like a mofo at highway speeds, and I think the vibrations are carried through into the cabin. Especially during winter when I'm carrying snowboards and skis atop.

Lastly. Besides the door panels, any other areas that might be a tight fit?

Thanks again! I'll do the community a service and post pics once I start into this madness and share my experiences.

Surprisingly some CLD tiles and the Thinsulate provides excellent noise control I don't hear any wind noise and when I go through a car wash the high pressure sprayers don't sound like they're going to pierce through the roof. The door panels were the only tight spots I remember... Around the seat mounts and rear heater you'll have to do some trimming to fit... Under the rear seat some trimming to fit is required too... The rear quarter panels are pretty forgiving

Reviving the thread!!

Just ripped out the back seats, gonna pull everything back there and put down some roadkill and then a layer of raammat ensolite over it. I noticed there is a ton of foam and rug crap already down. My question is can I fit the layer of road kill and the layer of ensolite underneath it and still tuck my carpets back in.

I have a 5th gen, but this seems to be the only thread allowed for these things, should I post in that section also?
