Sound deadening the doors was totally worth the time.

Yeah, actually, resonance is the issue. If it wasn't, then why did you install a CLD product instead of foam diffusers or absoption panels?

I mean look, if it works for you then great.

It does the same thing because the Siless is primarily a CLD tile with some foam sandwiched between an outer mass layer. The primary butyl layer against the car panel does the heavy lifting here. CCF is a poor absorption layer, and at that thickness provides neglible benefits; it is strictly a decoupler.

The outer butyl mass layer may block a tad bit of sound, but it's really not doing anything except adding weight here. Without full coverage you're going to have sound enter the cabin. That's one of many reasons why MLV has fallen out of favor as an acoustic treatment. It is simply is too hard to install properly to fully benefit from its use.

What that boils down to is the foam and outer mass layer aren't really useful here. For the money spent, you're better off buying CLD that will further reduce panel resonance. I suggest NVX because it's priced well for the reduction in resonance it provides and easy to get, not because it's the best product out there. If you were fully covering the inner door skin or a full covering of the floor and bulkheads, then maybe the Siless would be okay. But for what most people are doing at home, like the outer door skins and maybe a little extra here and there, it's just extra weight.

PS - resonance was what was coloring your music.

I'm done arguing because you're clearly challenged and believe whatever you want to believe regardless of what anyone says. The crazy thing is I installed the first layer of butyl deadener behind the speakers TWO WEEKS before I installed the Siless 3 in 1 because I purchased it locally on a day off and I had to order the 3 in 1. That alone made zero difference in the sound, I wouldn't have even installed the rest if it had. All it did was reduce the vibrations a bit when you cranked the sound and make the door feel a bit more solid. The 3 in 1 made a large difference, exactly for the reasons I mentioned. You can keep telling the multiple people on here they are wrong and you are right when you're assuming everything you're saying, but why don't you screw off and make your own thread about it and preach there instead of derailing this one?

"Yeah, actually, resonance is the issue. If it wasn't, then why did you install a CLD product instead of foam diffusers or absoption panels?"

Really? You're going to quote reply me and ask a question that I literally answered in the post you quoted. I'm done.

It's interesting to note that the folks disagreeing with you here are the ones who actually bought a product, applied it, and heard a difference (whether in road noise, the door closing, or tone/quality of music from the stereo). May I suggest you argue a bit less until you too experience the difference in the stock truck and then again with whatever sound deadening material you choose.

I went the same route as the OP and it's noteworthy how accurate the OP was in their assessment of the benefits of the products he used. I ran out of time after doing the driver's side (both front and back) and drove around for a week with the passenger side completely stock. The noise coming from the passenger side was noticeable, and I had passengers who aren't car people, or particularly observant, notice the noise from their side and one even insisted their door wasn't closed. Sexy graphs aside, unsuspecting folks who had no idea what I had done to the truck noticing the difference like that tells me that there's more to the siless than just "extra weight".

I agree with you 100%. I did sound deadening (doors) right after I purchased the truck, and only had time to do the passenger side before my wife's first ride in the new Ranger, she asked me "why is the drivers side of the truck noiser and why are the passenger doors more solidly built?"

sound deadening the roof of my non raptor did wonders (my doors are fully deadened and resonix black mat on the panels)

12sqft on the roof with 1" Resonix Black Mat acoustic fiber to fill the voids of the open area.

I keep think about doing the roof.... any tips on dropping the headliner?

Recline the power seats before you disconnect the battery and start dismantling. It's annoying but the deadening makes a big difference.

go slow ha. lots of small screws and clips. i did it on a hot day and was maybe 3 hours start to finish so wasnt too bad.

remove the headrests or recline the seats all the way back to let the headliner drop low enough to work above it

Anyone know how this affects PDR if you need it in the future?

I ask because I had a hail claim the first week I got my Raptor and they did great work but truck was pristine with no deadener applied at the time. I actually wish I would have had sound deadener material on hand to install while they had everything apart, would have made everything easier for me.

I installed deadener in the doors and roof and that was a lot of fun. But it got me thinking about PDR and how that would have to suck, assuming they'd even touch it.

Love the difference. I added acoustic foam behind the speakers. Overall I'm happy with the results but I definitely want more. I guess next will be the Mobridge amp setup for me.

I’m thinking of doing this next to help deaden the loud heavy rains, but I admit I’m intimidated by the thought of dropping the headliner :-( Hopefully I’ll get over that soon and get it done.

Me too! I watched the video...it seems "doable" but I think another set of hands sure would help.

Yeah -- I did it solo and getting it down is not too hard, getting it back in place would have been easier with a helper. There's a magnetic catch and some clips to align when putting it back up and that got a bit awkward.

But like others have said -- just got slow, keep the clips and screws and parts, disconnect the battery (there's airbags in the pillars).

I installed CLD (NVX) and absorber (Thinsulate batts and Resonix) this past spring. Even posted these pictures on here too help others with their installs. Only thing not done is the floor, firewall, and wheel wells.

I just did my door skins this past weekend. HUGE difference. I plan on doing the roof and back wall with 120mil Siless. I also installed a Kicker HS10 and new Infinity Primus speakers (5 1/2" rear and 6x9 components front). It's coming together.....

I got 3 different quotes today.
To do the Doors , Roof , and floor.
$1700 6-8 hr job
$2000 10-12 hr job.
$3000-4000 3-4 day job. lol
All quoting different brands and somewhat different type of materials.
No idea what is a fair price for this sort of work.
