Replacement for Jensen Entertainment Center

I find rv sound systems are garbage. what I would do if it mattered that much to me is get a good quality sound bar set up for the tv and replace the radio part with a deicent quality car sterio. I don't worry about the blueray as I have a Iptv box that I just bring with me if I know im going to have internet , if not we can watch dvd's if we have to, but don't realy turn on the tv unless we are using it as a house for work or kids sports.
