Hello all,

I am starting a project on upgrading the audio and adding an amp to the stock non bose system. As I have been digging through the items that I need. I am considering adding some type of Dynamat but most likely another brand do to cost.
My question is will one see a big difference in the brands of these products. I do realize that there are different thicknesses and materials but most appear the same. self sticking back and offered in pads or rolls. I am not entering an audio car show but would like to get the best bang for my buck on this. Main goals is to improve sound quality. better installation on hot days. reducing road noise is always a plus.
I am wondering what others have gone with and why. Presently leaning on the Siless brand but they do offer different options

I applied Second Skin Damplifier Pro to my truck and noticed a decent improvement; lower frequency of noise and a perceived reduction.

On mobile but some pictures can be seen here in my build thread #38

I didn't do 100% coverage, since it was not my main purpose for ripping out my interior, but still quite happy with it. So happy, I bought more and did the same to my appliance car.

Not sure if you're aware, but about half the design team from the Silverado was pulled off to do the Colorado - it got all the latest and greatest from that model, including lots of sound deadening material. Behind every nook and cranny is sound deadening. The little trucks are very quiet already.

If you're hellbent on adding more, anything rubber will an adhesive will work. Tires make more difference than anything.

I have the Bose system, it's been fine, but I'm not much of an audiophile. The Cadillac has it too and it's WAY better - in a 2013.

Not all sound dampening is created equal. If they don't show the density of the material and the thickness, don't buy it. Lots of really good cheaper options now days. I'd just browse Amazon for a couple days saving certain ones to a list and comparing them before I pulled the trigger.

I plan on doing the whole cab when I add my sub in the 3rd gen.

Post up some pictures if you end up doing it !

Heads up, you can't get the front of the headliner out without removing the windshield so I applied sound deadening to the roof by leaning it down from the rear. Also took the opportunity to delete OnStar while I was up there.

That's neat (not sarcasm). I noticed a fair bit of sound deadening in my 2nd gen already, a combination of vibration dampening goop on the floor and decoupling via ~0.5-1.0in thick foam underneath the carpeting or foam pouches behind plastic trim. Similar to my 2022 Bolt, but found more vibration dampening on that. I'm sure 3rd gen is great too.

Sound deadening was a secondary objective for me, as I pulled the interior to run power and RF cables. Figured while I was there, might as well. And it made a difference. I think especially the roof, though I could only lean the headliner down since you have to pull the windshield to get the front out.

Totally agree. In general, the more technical data I find published on a product the more confidence it inspires in me.

I have not found any sound deadening on my 2017, I pulled the plastic from behind the rear seat and just the outside steel also along the rear winow back of cab pillars, nothing there either
I took a 1/2in thick yoga mat and put behind the plastic cover behind the rear seat, seemed to help with road noise a little

Was there not a giant air duct/foam piece behind the rear seat panel ?

Great information, Thank you. I think the design team has a long way to go when I look at my white liner, back seats, grey armrest, and I think it may be a 3 colored dashboard. It's just horrible

Totally agree on your statement as I have read many reviews of many brands recently. I ending up ordering the Siless brand that works as a sound proofing and installation barrier but to be honest I am nervous if it the best product for me or not. Brands like Dynamat and other brands I can not justify as they were almost triple the cost.
I got the back all seats and paneling all ripped out. I need to losen the console next to remove carpet and try to fight with the headliner. Thank you ARCowboy for the tip on this as I am not removing the windshield and I am now scrapping the idea of painting it to match more of the inside of the truck.
I will be taking some photos of the work and so far all is just a little time and pertinence.

I've used Fatmat in the past. Works pretty good. Here's a link: https://amzn.to/3o4hCQe

I've used Killmat, NVX, Stinger, Noico and Dynamat. I can't say I've noticed any significant difference between them. However, I don't think my hearing is as sensitive as some ppl to notice anything beyond major differences. On my next project I'll try the Amazon branded one and see if it's any good.

I appreciate everyone's feedback as I learned a lot from reading all of the links. Some I think are still to push their own products. An interesting comment one made was smelling like asphalt. I got a mild oder from this and just added an air freshener. I used 2.1/3 boxes of the 36 cubic feet boxes. Flooring was done, back cab wall, and doors. Headliner was also dropped and installed. My truck is as quite as my Porsche now lol. Loving it
I think this was needed but I will be honest and say the floor may have not been needed but it is not that hard to take the seats out.
regarding the brand and cost. So far I am very happy with the purchase and I do not think some of the more premium ones would have made any difference other then a smell. I chose this one as it was the only version that mentioned it as in installation material and not just sound dampening.
great project it was now I need to finish the audio upgrade.

where do you think most of the noise was coming from?

Most of the engine noise was coming from the back of the truck. The door was a huge improvement. Especially the front doors had the most opportunity to fill due to the size. I should have test drove after each section to see what truly made all of the difference.
