Review on 🚗 Enhance Your Car's Acoustic Experience with Stinger RKX4 Roadkill Expert Series Universal Pack by James Salem

I bought this for my rear end. I used a Dynamat wooden roller for application and smoothing. I honestly didn't notice the difference, but the knocking stayed. Very disappointed. I only gave it 3 stars because I will leave room for error when installing it as I don't know if there is a special way to install it. I just cut it out, laid it out and rolled it out. They feel heavy and well built, I just wish it would solve my rattle problem.
