Great product - Add foam product for complete solution
Model: 36 SqFt(3.4 SqM)
Used in two cars with speaker upgrades. Easy to install but get the roller for assured adhesion.removes "tinnyness" from large metal resonators. Use with foam absorptive material for a complete system.

Great Product for noise reduction in Auto Use.
Model: 36 SqFt(3.4 SqM)
I use this on many builds to dampen the metal echo in cars, vans, and trucks. Just one sheet in the center of a body panel is a huge difference maker. You can also cover the entire surface and get added insulation value. The noise is greatly depleted and it's easy to install with a roller tool. Looks Great when done. Good Product I will use again!

Impressive Sound Deadening Solution with Enhanced Audio Quality
Model: NewSLS50_52
I recently purchased the Siless 50 mil (1.3mm) 52 sqft Car Sound Deadening mat, and I am delighted with the results it has delivered. Right from the start, I was impressed with the packaging, which ensured the product arrived in perfect condition.
One of the standout features of this sound deadening mat is its ease of use. It was a breeze to cut and modify according to my specific needs. Whether I needed to cover specific areas or customize the size, the mat accommodated my requirements effortlessly. This flexibility made the installation process a breeze.
The Siless Sound Deadening mat has proven to be highly effective in reducing outside noise within my vehicle. With just a half cabin install, I noticed a significant reduction of approximately 10 decibels, making my driving experience much quieter and more comfortable. The mat acted as a reliable barrier against external noise, allowing me to enjoy a more peaceful ride.
Furthermore, the sound quality from my vehicle's audio system experienced a noticeable improvement. The Siless mat effectively dampened vibrations and minimized resonance, resulting in cleaner and more refined audio output. The mat's thickness of 50 mil (1.3mm) ensures optimal sound absorption, contributing to its effectiveness in creating a quieter and more enjoyable driving environment. I can now appreciate the full range of tones and enjoy a more immersive music experience during my drives.
Overall, I highly recommend the Siless 50 mil Car Sound Deadening mat for anyone seeking a reliable and effective solution to reduce noise and enhance audio quality in their vehicle. The easy cutting and modifying process, along with the excellent packaging, contribute to a seamless installation experience. With a significant reduction in outside noise and an improvement in sound system performance, this sound deadening mat has exceeded my expectations.
