Product arrived well packaged and is a quality item - every bit the enthusiast consumer product you would expect it to be.
My truck is what I lovingly refer to as “poverty trim” - so while I can’t speak to additional sound deadening/road noise mitigation effect to my ears, the retention of mid-bass within the cab - the way it feels like every bit of thump doesn’t leave the vehicle at all - is dramatic.
In short, death metal go thump thump thump and shakes everything. Wife hates it. 10/10. If you ever thought “maybe I should do a minor sound upgrade because I could use 10-15 percent more” - stop here. Save money,
