            Fun project, big impact

            It wasn’t particularly difficult to strip most of my rubicon’s interior and apply the hardtop strips and the half floor kit. It did take a few hours, but I also wasn’t working in a big hurry. The road noise is definitely reduced, and even better- the stereo/audio acoustics are *significantly* improved. Worth it completely.

            The best option around

            Don't waste money on the OEM stuff these are a little less expensive and a much better quality. I have used these in two jeep products and they are by far the best.

            Immediate difference

            I ordered the sound assassin and headliner kit in July and noticed how much cooler my black on black 2 door JL was. In November I ordered the sound assassin complete floor system with the heavy duty roller. My jeep is so much quiter and the stereo system sound improved. Best investment so far!!!!!

            What a MAJOR difference !!!!!

            I am so happy that I spent the time and money to install the Sound Assassin. It has made such a difference in the overall driving experience in the 2018 Wrangler JK. It has really significantly reduced the road noise in the cabin and it is so easy to hold a conversation on the freeway. This was the best $250 I have spent on my wrangler as before this, I would not drive it on a long journey. Now I am more than happy to. Great product. I would recommend including one more sheet of the product with the full car coverage, as I could have used one more sheet to finish the install.
