I just had an after market Clairion 4 channel amp installed by a friend and the red airbag light in the instrument cluster stays on. How do I reset it and turn it off? Also, the whine from any electrical component, especially the engine whine, even when the head unit is off is awful....what has he done wrong that I may correct? It sounds as if the speakers are powered on even if the head unit is turned off. Thanks for the help....oh, it isn't a JBL head unit...new rear speakers installed during amp install.....the amp is a 400 watt. Alex
ps,,,it's a 2006 Avalon XLS
