Keyword here is “branded”. McIntosh doesn’t make the head unit, amp, speakers and radio modules - those come from Panasonic, Denso(they bought out the automotive side of Fujitsu that’s a long time AV/Infotainment supplier for Toyota), Clarion(now owned by Fareucia, and a long time Nissan/Subaru audio supplier), Pioneer, Alpine, Visteon or Delphi.
Harman, now a part of Samsung enjoys a dominant position in “premium” OEM-level audio. The “branded” JBL/Mark Levinson/Harman-Kardon/Revel/Lexicon/Infinity and now B&O Play in Ford and Audi are all tweaked versions of what Becker(also a long time Mercedes/Porsche audio supplier) makes. The head unit will still come from Panasonic and Pioneer in those cases.
if anything, McIntosh will put their signature on the head unit’s firmware/UX and their Sonic signature on the amp’s DSP. The aftermarket will come up with solutions to replace factory amps or head units on those. Kenwood now makes a 10” floating display and Pioneer’s latest has a modular display with the aim of OEM replacement.
