DynamatDynaPad Heavy Duty Automotive Insulation – Noise & Heat Dampening Kit for Car Floor, Reduces Road Noise – Easy Install – 32” x 54” x 3/8”, 12 sq ft

What I like:I only had the Dynapad installed on the engine tunnel area and it has already made a HUGE difference to the annoying sound level.I wasn't able to listen or speak on my speaker phone before. I only had the dynapad installed on the tunnel area where most of the noise and heat comes from. It has made a big difference.I cut and installed it myself. The carpet is heavy and sit well on the engine tunnel. I do not want to use glue on the carpet as my restored BJ40 is known and very prone to rust. I am afterall living in a humid climate.This is NOT a closed cell foam. It's very porous, so I would use this on area where water will not sit or stay stagnant in case water seep unknowingly in from some where. The lighter side foam absorbs water. The darker side is more resistance to water.I will be using Dynadeck for the rest of the car.What I dislike:Its bloody expensive for a small carpet for a 32 x 54 in.

I was looking for a way to cut down on the road noise in my C6 convertible. I bought this mat cut it to fit and placed in the trunk, cut the noise tremendously. I'm a second one to put behind the seats to cut more of the noise.

I just fully restored the interior of my foxbody Mustang. Between the supercharged motor, full exhaust, and very firm racing suspension, the car is LOUD inside and out. After stripping out the entire interior and trunk down to bare metal, I first applied a Foxbody coupe specific matched Dynamat kit from Late Model Restoration. But there were a lot of flat metal panels left untreated, and flat panels are what tend to vibrate the most. So I got a couple of generic Dynamat kits to cover more area. And then I put this Dynapad over the Dynamat on the floor pans and able hump area. Overkill? Maybe. But considering how loud the car is to begin with, I figured it couldn’t hurt anything but my wallet (this stuff isn’t cheap, haha) and maybe the penalty of added weight (so what, it’s a light car with over 670 HP and nearly the same in torque, so what’s an extra 90 or so lbs of sound dampening?). I can say that even with half the interior still out of the car, the reduction in Noise and vibration is noticeable. The car is still loud as hell, but to a lesser degree and the exhaust drone isn’t as palpable. So while not cheap, this stuff works, and is very easy to cut and install.

I am writing this review for all the people who are on the fence about getting dynamat and dynapad for their car. I have both us these products in two different cars. It has made a very big difference in both of them. Car number 1 is a Nissan 240sx fastback with a sr20det turbo engine and a full 3 inch exhaust. Car number 2 is a 2016 Toyota Yaris 2 door hatchback. You will need to get at least 1 mega pack of dynamat extreme to do most of the car. 1 mega pack did the entire floor, roof, trunk area and rear quarter panels of my Toyota Yaris. I will need to get some more to do the two doors. I used 2 rolls of dyna pad in this car. I used 4 rolls of dyna pad in my Nissan. 1 roll just for the fastback area. If you only use dyna mat its good to about 30mph. At highway speeds you won't really hear a big difference. That is where the dynapad really helps. The faster you drive the more road noise enters your vehicle. If you are sitting in either car and they are not running they are extremely quiet.

-- update -- If it's audio clarity you're after, then I'd say dynamat alone is better. I love that this dynapad reducesoverall noise in the cabin, but it did muffle the audio some. So, for my Jeep, I've purchased JKU-pods to be attached to theroll bar in the rear of the cabin and disconnecting the soundbar speakers that point straight down to the floor where it ismy belief that a lot of sound just gets absorbed right into the dynapad. The soundbar speaker location is bad no matter what,but I'm hoping that having the rear speakers actually pointed across the cabin will make a notable difference so that I can enjoy the benefits of both the dynamat and dynapad.-----I don't know if adding this made my audio better than just dynamat alone. I did notice a hugedifference after the dynamat which I also put in the doors. I did notice less road noise for sure after the dynapad,but again I'm not certain that the audio is better. In fact it may have become a bit muffled afterthe dynapad, but I still love the way my new Head Unit, Amp and speakers sound. Like a rolling studio.

must-have for all my old cars

This mat is very dense, very heavy and easy to work with. However the price is high and for it to be effective I think you'll need to cover your entire floorboard with this stuff. I used it and the Dynamat Xtreme to covert the front driver and passenger foot wells and didn't notice a tremendous difference. But then again I have a late model car, if you're trying to quiet an older car then you might get a better ROI. I do know that the Dynamat Xtreme does in fact deaden resonance in the doors but since the floor is already stiffer and has features (meaning it's not a flat piece of metal) I'm not sure if it's as effective on the floor as the doors.
