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.
