    What direction is that looking from? How easy/difficult is the door panel to reinstall after layering it up?

    Inside out - left to right. This is the view from the passenger side door jamb near the door latch.

    Getting the card back on is plenty easy as long as you trim the treatments around the latch release carefully. It's good & snug, but that's the idea.

    Nice I like it. Where do you recommend buying MLV and CCF from? Apologies if you mentioned this already in this thread.

    I get MLV from TMSoundproofing

    I get neoprene from Foam by Mail. Get the 'high quality'. It's a much higher density - really nice stuff. You can use scrap for all sorts of things - like custom beer koozies :D

    Thanks. I'm feeling like I will go this route. I had been planning on getting the RAAMMAT kit but everywhere I read, I'm finding 25% CLD coverage plus MLV and CCF is the way to go. It's looking like it will cost more but will be a more effective end result.

    There are places we can cut corners in mobile audio, but sound deadening seems to be a pretty rigid exception. There's a minimum buy-in to get it right. Then again, it's a massive upgrade at $300-400. You go from a rattletrap of a truck to a luxury car environment with an insulated cabin. That's money well-spent IMO. That and you need less effort from your stereo gear as you aren't overcoming all that extra noise.

    Just an FYI, you can get MLV from Soundproofcow.com for cheaper, even with the shipping costs factored in. I paid $241.92 shipped for 144 sq ft. of 1/8" MLV, which works out to $1.69 per sq ft vs. the $1.99 per sq ft. on TMSoundproofing.


    EDIT: Looks like they have a 15% off coupon code (Moo440) on all materials. So it will end up being less than the $1.69 per sq ft it cost me.

    Thanks for the heads up! I’ll check them out.

    I just tried to look at it now and it gave me the same error.

    From your pic you posted yesterday, you put neoprene on both sides of the mlv? Would you do the same for the back wall as well? Did you glue each layer together?

    I think their website must have recently went down because i am getting the same error. It did work an hour ago when i was pulling up the link to provide on here. I would say try again in a few hours. Maybe they're doing website maintenance or something.

    It's working again haha...

    Any idea how their Sound Deadening material compares to some of the other mentioned so far? I was considering using CLD tiles from Sounddeadenershowdown before looking at this site.

    Appears to be much cheaper, it's worth a try. The overall thickness between the two, Soundcow's RoadBlockR CLD (78 mil) vs. SDS's CLD (80 mil), seem to be negligible.

    Now I see why the cow's MLV is cheaper. It's not virgin material (uses recycled material). This can mean smells that never go away and it may not be as resistant to tears and chemicals as virgin material. They also make a claim (several times actually) that this stuff doubles as a damper (err they call it a dampener o_O). It does not. It could potentially act as somewhat of a constraining layer with a suitable substrate, but as it stands it's not going to work as a damper. MLV is a barrier.

    Never heard of anyone using their CLD, but at $3.63/foot before shipping I'd personally use one of the many other proven options. The thicknesses they report on the website are absolute hooey as well. They're trying to say their damper uses a 4mm (about 3 pennies stacked) constraining layer and a 20mm thick substrate. That's an inch thick total. Maybe they meant mils while they actually write mm. If that's the case, it's not going to wind up in the bin with the better dampers. Heat tolerance is MUCH poorer than SDS at 140F compared to SDS' 400F. That's enough reason to leave it alone. Boosted, IMHO you were on the right track with SDS CLD tiles. From experience however I found it difficult to work with on the back wall. I'd use the CLD sheets for that.

    While I'm at it, since the soundcow goes there repeatedly and it's the subject of this thread, there is dampening and damping. They aren't the same thing. Dampening is what you do with a garden hose - generally bad for auto interiors. Damping refers to changing resonant frequencies and amplitudes and is a well-understood branch of physics. There's a link to a paper in this thread which explains CLD (Constrained Layer Dampers) in greater detail than probably anyone here will care to read.

    Thanks for that clarification @rob feature . That is very helpful. I think I am going to use the material estimates on SDS along with my truck's measurements to estimate how much of each material to buy. I'll probably go with SDS CLD, and the MLV and Neoprene you recommended earlier to do my doors and back wall. I was also looking at the HMF that SDS sells as well to put in the headliner.

    No problem boosted - good luck with your shopping and install. That HMF is good stuff I hear. Haven't used it yet personally but it gets good marks. Looking forward to hearing what you think about it.

    Interesting, thanks for all the clarification. I've used SDS CLD before. For my Tacoma i used Second Skin Damplifier. I didn't buy anything from Soundproofcow.com except for the MLV. It doesn't smell (or stink) any different than previous MLV i've used before.

    Good to know. Even the virgin MLV from TM had a slight odor to it out of the box, but I can't say it wasn't the box & tape. Never smelled it once installed in a vehicle.

    Silicone on those rear vents though - I'd expect that to linger. That's a good place for butyl rope

    Just did my floors and back wall today with mostly double layered Noico 80mm. I put my drivers seat back in for a coffee run.

    The carpets not even back in yet and WOW what difference! I can’t wait to finish the back floor, doors and ceiling! 43B21473-E1DA-4E54-929C-AD10D41F7910.jpg2DA73986-8F61-416E-BBC9-8AFC2EBFDB66.jpg 949EC0EC-D05F-40A1-9120-0FDDC1B10A41.jpg
