Everyone wants a killer stereo that rocks. You can’t just roll out in your car without something fabulous to listen to. The factory equipment just won’t work for those who demand more, especially if you are trying to show off. You have to be able to turn up the music and be heard—it’s all part of the game. If you’re going to roll, you know the rules: you have to roll hard and that means your entire stereo system has to be up to the task. Nothing is worse than blasting a stereo and hearing everything rattle and shake. That’s a huge no-no. There is a simple solution to this problem, however. To do a proper stereo installation, you must first lay a solid foundation. The first layer of this foundation is called sound damping or sound control.
