it has made a noticeable difference in reducing road noise and improving the sound quality of my audio system. The package comes with 20 sheets, covering a total of 20 sqft (1.9 sqm), which was enough to cover key areas in my car. The 80 mil (2mm) thickness offers excellent sound insulation, and the butyl material is durable and effective at dampening vibrations.The adhesive backing makes it easy to apply, and once it’s in place, it stays put. I also found that it significantly reduces engine noise and outside sounds, making the driving experience much quieter and more comfortable. However, cutting the sheets to fit specific areas can be a bit tricky.Good: • Excellent soundproofing: Effectively reduces road noise, engine sounds, and vibrations. • Easy to install: The self-adhesive backing ensures a hassle-free application. • Durable material: The butyl construction holds up well and provides long-lasting noise insulation. • Improves audio quality: Enhances the car audio experience by reducing background noise. • Sufficient coverage: 20 sheets cover a large area (20 sqft), enough for most cars.Bad: • Difficult to cut: The thick material can be a bit challenging to trim for smaller or irregular areas. • Adhesive strength: While the adhesive works well, it may require additional pressure or a roller to ensure full contact, especially on uneven surfaces. • Limited flexibility: The stiffness of the material can make it harder to apply on curved or awkward areas inside the car.Overall, the DKIEI sound deadening mat is a great solution for reducing noise and improving audio quality in your car, though a bit of effort is needed for precise installation on tricky areas.
