KILMAT 80 mil 36 sqft Car Sound Deadening Mat, Butyl Automotive Sound Deadener, Audio Noise Insulation and dampening

Ive done all sorts of upgrades/enhancements to my cars over the years, and installing sound deadener has been the most transformative. Sure, upgrading the stereo/amp/speakers all at once is hugely transformative, but its also expected to make a huge difference. The reason I say sound deadener is more transformative is that it improved things in many unexpected ways, on top of the expected reduction in road & mechanical noise. Background on my vehicle: - Medium sized pickup truck with extended cab - 2006 but only 40,000 miles, so enough miles to develop some rattles - 4 doors (2 normal, 2 smaller) - Smaller doors provide access to extended area for storage or jump seats I took the driver/passenger and jump seats out but only moved the carpeting out of the way vs fully removing. This, and because I didnt remove the center console, meant that I was able to cover the sides of the drivetrain well but not the top . In my truck, most of the mechanical noise comes from the engine, not the drivetrain. What I covered with 72 sq ft of 80 mil mats (i.e. purchased 2 boxes of 36 sq ft): - 4 doors - Rear of extended cab (area facing bed) down to the floor - Ceiling - Driver/passenger footwell up thru firewall - 3-4 wide area running between seats and doors from front to back - 2/3 of area below drivers seat (was too lazy to remove passenger seat again just to apply a single sheet) - 1 sheet of mat leftover I was very thorough. I removed the speakers in the doors and covered the area behind them (I also installed speaker baffles, which improve the sound quality and provide some sound deadening qualities). The rear doors have built-in pocket storage areas so I ended up covering the exterior metal panels of the doors and the some of the interior metal panels. Maybe overkill, but those doors were also the source for a lot of road noise. Expected improvement: significant reduction of road and engine noise. This stuff delivered the goods. My 9 y/o immediately noticed the difference and said something before I could tell her I was done. And this was on city streets, so not even highway. Its that noticeable. Hands-free phone calls, music, talk radio, you name it, all sound much cleaner, crisper and without having to crank it up as much. Unexpected improvements: - Doors close with a more solid feel - Near silence when going over potholes and changes in pavement - Sensation of that I installed a new, more sophisticated suspension because everything feels tighter and smoother All in all, money well and one weekend well spent. Installation tips: - Run a small heater if installing in temps below 60 degrees. The mats will adhere better. - Buy the metal rollers to make sure the mats are completely flat and fully adhered. - Before removing the paper backing, put the mat into the desired location and press hard on the areas that need to be accessible (screw holes, wiring, etc) to create an impression. Then use exacto knife or razor blade to make the opening marked by the impression. Be sure to double check all access points twice so you dont find yourself all ready to put everything back together and you have to find the one you covered. For rubber gasket access points, I cut a path around the edges so you can remove the gasket, but theres still mat on the bulk (center) of the gasket.

I installed this throughout my Montero Sport, mostly in the rear cargo area to quiet the many rattles that come from 200k+ miles of driving around Montana/PNW. I pulled off the interior trim panels and placed a layer on the inside of the exterior sheet metal fender panels, then a layer on the inner sheet metal panel that frames out the cargo area and the trim panels clip in to. I got about 70-75% coverage, mostly because I was being a little lazy and a bit rushed, but I also didnt want to interfere with any holes that were used for trim clips. Or run out of the 65sq/ft before ordering more. I feel like the 80mil material is heavy/dense enough that 100% coverage wouldnt really be necessary. I did do both front doors so far, along with most of the rear and there is definitely a difference. A lot of the rattles are completely gone, while the bigger, louder noises that came from offroad driving are considerably quietier. The loud banging from rocks getting thrown into the wheel wells is much less noticeable. The doors close with a much more solid sounding thud with no rattles then before. I have decent Rockford speakers in my doors but nothing loud enough to notice any sound quality differences as far as stereos and such are concerned. This product will probably stick to anything, but I strongly suggest giving the surface a wipe down if its dusty. Its repositional as long as youve only got a few square inches stuck down, any more than that and good luck. Cuts pretty easily with a utility knife on a scrap of OSB or something. Definitely worth the money and time invested to not hear everything rattle on long off-road trips.

I am in the midst of upgrading the audio system in my (new to me) 2009 Acura RDX. Six of the ten factory installed speakers had seen better days. The voice coils were shot in several of them found in the driver and passenger, front and back doors. There is a lot of great information available on you tube videos on steps to take to improve the sound quality of your auto sound system. Of course, replacing the speakers with some quality aftermarket models is an obvious first choice. I learned that another item to consider is Kilmat Car Sound Deadening Mat, available in 80mil and 50mil thickness. The thicker the better is good to consider installing when possible. Cut out paper templates of the various shapes and sizes of the mat for good fitment. Disposable surgical trauma scissors do a good job of cutting the mat to desired size. Be sure to also purchase the 3-pack of installation rollers. It is important to roll over the mat with the rollers to ensure proper adhesion of the sound deadening sheets to the metal door panels. Kilmats waffled aluminum top sheep product design easy shows where the mats have been rolled. The installed mats do add some weight to the vehicle. However, the marked decrease in sound reasonance is a welcome trade-off. Even installing mat to ~25% of the door panel will result in considerable sound deadening.
