Contour Enthusiasts Group Archives Forums Modifications Audio new Kenwood, sound degradation problems

take the CD out when your having the sound issues after a half hour... is it hot??? after an hour in a kenwood it should be warm, but not super hot. Try what Natestour said and try running the HU outside of the dash, see if it overheats or changes anything that way.. All I can say is make sure that the heatink is clear of jumbled wires. The heatsink on your unit is silver right in the middle of the back.
If it still overheats then it sounds like one of the mosfets in your HU is not connected to the heatsink internally.
