hi 2 months ago I bought nx450h plus and very disappointed with its audio system. Basically I’m a music lover and the audio system in my car is very ( below ) average. Bass is just unbelievable when we spend so much. How come Lexus made this decision? When we buy a luxury car, the audio system is most important isn’t it? So, has anyone changed their audio system recently? If, what’s the system name? Pl share your story….
