I have no problem with the sound levels of the system from 2100-2800 and from 3100-8700. yet when the car settles into the 2k and 3k ranges it produces a sound in the cabin when the windows are up that drills right into your skull. even when the radio is up at about 70% volume you can still feel this overwhelming hum. unfortunately when driving at 80MPH on the highway (3krpm on auto) and 55mph on the side roads (2krpm on auto) driving the car becomes a complete annoyance not because of volume, but a mind drilling hum.
