The dynamics of Kia Sorento 2 may be silenced for the following reasons:
Option 1. Due to the sharp cooling of the KIA Sorento II salon, the metallic parts of the speakers freeze at the condensation of the dynamics.
Option 2. The rubber balance of the rubber makes the elasticity. In this case, when the music system is turned on, the dynamics will not work.
Option 3. Condensation will be measured on the boards of the audio system. In this case, the circuit board may be short circuit when the system is powered on. In some cases, there may be an open fire.
Before you turn on the music, you have to warm up the salon.
