If the car stereo or amplifier powers off when raising the volume, then there may be an issue with installation. This usually occurs when the ground wire is not connected properly. However, it also can occur when an amplifier becomes overloaded by connecting too many speakers. It is recommended that a professional installer be consulted to ensure proper installation.
WARNING: There is a risk of personal injury. Never install a car stereo system or amplifier without first disconnecting the car battery. Failure to do so is dangerous and puts you at risk for electric shock.
NOTE: It is recommended a professional installer be consulted for installation. Sony does not provide installation assistance.
If the installation was performed or inspected by a professional installer and the issue cannot be resolved, service may be required.
