In this review the Wagoneer's McIntosh audio system was reported to be the best and an audiophile's dream.
Verdict: No matter what kind of driving I was doing — sitting at a light or cruising on the highway — the McIntosh system in the Grand Wagoneer offered up the best car audio I’ve ever heard. The price of admission is steep with the 23-speaker system only standard on the Obsidian and top-of-the-line Grand Wagoneer Series III (optional on Series II as part of a $3,995 package), but I don’t think that anything even remotely close to this Jeep in price ($109,025 as tested) is capable of offering up a superior audio experience. The premium sound arms race just keeps picking up steam, though, and I’m excited to see what comes next.
McIntosh steps up big with the 2022 Jeep Grand Wagoneer's in-car audio system.
