Design EngineeringBoom Mat Black Complete Sound Deadening Kit Compatible with 4-Door Jeep Wrangler JL (2018-up)

First of all, when I tried to buy this, the message "This Does not fit your Gladiator" popped up. No idea why it said that, and I nearly didn't buy it, but it DOES fit my JT. Perfectly. This is an Amazon glitch, so they need to fix that.This liner looked great in the box, and it looks great installed. It is highly recommended that the top be taken off to put this on, but I did not take it off. As a result, I have a couple of small errors, but no one will ever notice them but me. It was difficult doing, and it required considerable strong words, but I hate taking the top off. If I had to do it again, I probably would take it off, just because I like perfection.It fits great, and it looks great. I got the white, and it's hardly noticeable. A couple of the backer foam strips were a bit to long, but I just trimmed them off.I just finished the project, and haven't driven it yet, but I anticipate a much reduced sound level. I applied it in the sun (and my top is black) and I could tell a huge difference in the heat coming through as I did each panel. That alone is worth the price.This adhesive is fantastic. It's instant adhesion, so don't let it fold back on itself. Buy this liner! You won't regret it.

OK, wasnt really sure what to really expect with this. Reviews were mixed. The installation is pretty simple. I did take the rear top off my Gladiator but I just rolled it into my bed cover and applied the BoomMat where directed that way. Made that part of the job really easy and it was the first time I had removed that part of the top since buying it a year ago.The install is easy overall and if anyone is unsure if this stuff actually reduces outside noise, take your Jeep through a touch-less carwash before and then after. You will definitely be able to tell the difference.I think it works great! Had one middle piece that wasnt quite cut right but a similar section of the front toos isnt even done in the instructions, so I just didn't put that one in the rear top either.All in all, happy. For this price, its worth it. We’ll see how it holds up to the weather impacts this summer.

Perfect fitting, accurate cut parts, improved sound and temperature control. Needs to get better on the glue,after a few days needs to reinforce with 3m double tape to ensure in place in some corners.

At initial glance when this kit arrived I was admittedly doubtful this would make much of a difference as it looked and felt very lightweight and mediocre, but I’m glad to report I was wrong. After a few weeks exposed in the Arizona sun in July, I’m happy to report I was wrong: this kit makes a SIGNIFICANT difference in lowering the temperature inside, especially when paired with a windshield visor. A must have for anyone living in a hot climate like mine here in AZ. The instructions are clear and easy to follow. Be careful, the adhesive on each piece is extremely strong. Overall, very glad with the purchase. We shall see how durable it is by the end of summer.

The product came with no wrinkles, in pristine condition. Installation instructions were a breeze, and the whole process took less than an hour (with taking the whole roof off.) Road noise level is definitely down, and it's easier to listen to tunes and talk to each other in the cabin.Make sure to properly stick it, otherwise it gets the wrinkly effect, which some end users captured. Not over stretching it or pushing it into the corners will get you the perfect result. Killmat IMHO is an overkill, since this set comes with the foam strips already, and there's plenty of buffer.Some folks said you don't have to take the roof off, but with 8 bolts, just take it off and do it right instead of trying to work around the speakers (unless you have baby hands).

Even if you are a little OCD, you will not like this kit. I got the full kit including the side window frames, I wish I hadn’t. The cuts are off just a little here and there which was my first concern. Second was their warning of “don’t stretch the material” when applying. The problem is, at least with my kit, sometimes the material wouldn’t come apart from the adhesive backing. Because of the extra strength needed, it would get stretched. The shape would change just a tad and that lead to wrinkles in the material I would have to try and reshape. I will say this, their adhesive is top notch. If it wasn’t, I would have pulled it off, reapply the backing and returned. The adhesive is so good, after just a short time if you would try to remove the material it tears and falls apart, the reason I feel struck with this product. It does block heat and sound on the areas it covers. All areas that remains white, still hot to the touch in the Florida sun and radiating heat. For this reason as well as wanting a more professional/factory installed look, I wish I would have spent a little more and went with the full interior roof package another company offers. LEARN FROM MY MISTAKE. Since you have to take the roof off for this install, go with the other better product that requires roof removal as well.

I would definitely suggest. Helps the inside interior for sound , cool and heat.
