Review on 🚗 Enhance Your Ride: KILMAT 50 mil 25 sqft Car Sound Deadening Mat, an Automotive Audio Noise Insulator and Dampener by Adam Gardner

This product is an amazing price for what you get. I have an electric car and the lack of engine noise (especially on freeways) makes every other noise more and more obvious. Also, the insulation in my car door wasn't staying where it was supposed to, leaving me with some cold air. I've spent 45 minutes on each door (I've only done the back ones so far) and it's already changed the world. The cold air no longer passes and the noise from the back seat is quieter. Placebo maybe, but I feel like the extra insulation in the door helps the speakers sound better. I think I have enough to do my front doors but if not I'm happy to buy another pack to finish the job. It's worth it!
