The McIntosh system is available only on the top trim lines, and the blue "meters" and badging are virtual on the display. The speaker distribution is better than the base and mid-line sound package and performance is supposedly pretty good. Mc was looking for product placement and Jeep is the most successful domestic brand in the Stellantis/FCA group. It is a large car system, high-powered (1375W, class D, DSP, 19-23 speakers, depending on the model) and is slotted above the mid-spec Alpine system and a non-brand base system.
I can't see how this will hurt the brand. It is a draw in that it is Jeep-exclusive, at least for now, and it is a broader market than the very limited placements McIntosh has made in the past. They already do some bespoke marine installations.
Given the need for every premium audio brand to establish its brand identity, this is far from the worst thing a company could do.
