Great quality

Good product. Used for inner roof and doors of my hotrod truck. Will purchase again.

I installed this product in the doors of my 2006 Mazda MX-5. Do they reduce road noise? Probably, but the reduction by just doing the vehicles' doors is minimal. BUT noise reduction was not my goal.Improving the radio performance and sound quality was my goal. The sound deadening instalation does change the sound. The aftermarket system is a Sony AX5600 head unit, door speaker are Kickers KS 5x8. Kicker HS8 subwoofer behind the passenger seat.The sound: The highs will be less tiny and maybe not as loud. The middle tones impoved in clarity and are easier to hear. The singers voice does sound better and more seperated from instuments. The bass distortion is less. The bass hits hard, but the low end rumble of the bass is reduced. Noise vibration from the door is greatly improved. I adjusted the subwoofer to address the loss of low end bass rumble.The overall sound quality did improve. Plan to have about two hours per door for installation. This includes disassembling the door, cleaning the door interior and installing the sound deadening material. There are videos on YouTube. Watch a video for tools needed and if you are up to the door disassembly process. I would do it again, because I have an ear for detail and quality sound. The second reason I'd do it again is it only costs me $30.00 and about 4 hours in the garage on a hot day. I used 10 square feet of sound deadening material for both doors (19 sheets)If your goals is to reduce road noise. My understanding is the wheel wells is where you should start. I don't have experience with this installation, but there are videos on YouTube.Good luck.

I bought 2 different types of the "same thickness" of sound dampening from two different brands. This brand was much thicker and denser in reality. It worked well to quiet down the metal vibration and I believe it is a great choice if you're looking to balance cost and performance.
