I test drove a Jeep with the upgraded system in the past 14-21 days. Not impressed at idle, even less impressive while driving. I blame the lack of deadening in the doors for the low end failure. Its possible if that issue is overcome it will greatly improve overall performance. Not a bad upgrade though.
Who is Gonna Buy A New Jeep Grand Wagoneer For the MacIntosh Stereo?
Not I, Just wondering.
