I think most factory stereos would be the equivalent of HTIB or a sound bar
. I really don't know what all the new vehicles have but from being into car audio in the past I doubt they still come close to what you can get for a fraction of the price doing things with aftermarket parts(but quality install/labor is expensive if you don't install things yourself). But most are sold as part of a premium package so you probably don't have much of a choice in it.
