The difference may be in that the 2024 is not really alpine speakers from what I gather, they just put their name on some cheap Chinese made speakers. Perhaps your 2014 alpine system has real alpine speakers? Plus, as I said in another post, the 2024 head unit only has one full definition speaker and that is the rear doors, everything else is mid and mid base, so its muffled. When you combine that with low definition satellite radio, then the 2024 is probably not going to sound as good ad your 2014, although I don't know how the 2014 is setup, sound stage wise.
