Is the Auto Volume Level option engaged? If that is your issue, I have read other members disconnect the microphones on the rear passengers headliner. I hope someone better versed in this technique answers your query.

The speed volume is turned off. The system does it all on it's own. I'm considering replacing the head unit with an after market unit. Hopefully that works. If not I'll start slowly replacing the lamps as well.
