Remove dangling accessories

Some cars come with accessories like iPod docks which stick out of the stereo itself. These should be removed whenever you turn off your car otherwise they can become loose and damage to your stereo.

Don’t let water get into the CD player

If you leave a window open just a little and it starts raining and reaches your stereo, this could damage your whole system because water could easily flow inside and reach electrical components. If this occurs just remove the faceplate of your stereo and dry it out thoroughly.
