The marine stereo is designed with the appropriate marinizing techniques and provides to counteract the effects of marine agents such as salt, humidity and high sun exposure.
Car stereos, although often similar in size and appearance, do not provide these production techniques and would therefore have a very short life on board a boat.
Not everyone knows that the most dangerous trap is humidity (sometimes more than salt), especially if the stereo is left inside the boat even in winter. In fact, the humidity concentration in a boat (except in summer) is almost always high and constant, so that the internal components are subject to continuous aggression of this element.
Appropriate marinizing can also prevent the effects of prolonged exposure to moisture.
While the degree of UV protection plays an important role in preserving the original aesthetics. In fact, poor coatings could change the original color in a few days of sunshine and deteriorate the quality of the body itself.
