Hello so I have no idea at all and don’t know what to look for or how to install something like that. Can someone tell me what you have to pay attention to with a good system and what you need for it. She should listen well but also not be too expensive. A good subwoofer is important to me. I don’t have a car yet because of more precise information, but I’ll get it soon. And 2 more questions: Does good sound really come from the beginning, because with a home cinemasyst he comes to every side? What are kickbass speakers?
