I have yet to see the raw parts on either the MX950 or MX1375 systems but I would be highly suspect of the actual hardware and how it was sourced, *especially* being a Chrysler product. What I mean is, what I consider largely the best automotive audio system on the market… the BMW Bowers and Wilkins Diamond system uses actual B&W speaker drivers and miraculously, even Diamond tweeters just like their home counterparts. Can’t speak to the amplifiers, but the rest of it is very much B&W.
Stellantis on the other hand, remarkets about 5 different sound system brands that all sound largely the same (Alpine, Harman Kardon, Beats, “unnamed hifi”, Infinity, Kicker etc etc) and for example the Kicker’s Class D amp module was on parts express for a long time for all of about 50 bucks.
I heard the MX950 recently in a Wagoneer. It’s a very good sounding system. But without A/B’ing with some of the others I can’t really say how much better it is. The nifty meters display on the infotainment screen is sadly, mostly a gimmick… it’s movement is so glitchy as to be unusable. Hopefully someone soon will locate the part numbers or dissect a door panel on one of these Jeeps to find out if the drivers are truly McIntosh manufactured.
Another thing that would be fun to see again which I believe Edmund’s did many years ago is a shootout of the current crop of top of the line systems: We now have competent systems from Revel, B&W, AKG, McIntosh, Burmester and at least briefly, even Krell was in the game. Although Samdung now owns many of these car audio brands and Becker so the actual differences between the Harman International/Samsung based systems would be interesting to see.
