Introduction of sounds outside a vehicle is automatically controlled according to a driving state of the vehicle. In a vehicle, a microphone device that collects sounds outside the vehicle and a speaker device that reproduces the collected sounds are installed. When a gear position for the vehicle is a reverse driving position, and until the vehicle reaches a predetermined speed for the first time after a key position in an ignition key switch is switched from an off position to an accessories position or an on position, the collected sounds are reproduced. The collected sounds are transmitted to a car navigation device or a car audio system via wires or wirelessly. When the sounds outside the vehicle are reproduced, sound reproduction in the car navigation device or the car audio system is stopped and the sounds outside the vehicle are reproduced at a set volume.

An amplifier that employs ultracapacitors to accommodate the peak power needs of an electrical system, such as car audio system. The amplifier operates off of a primary power source for average signal power levels and then uses the ultracapacitors when operating at peak power levels. As such, the amplifier can operate off of a primary power supply that supplies less than the peak power required by the amplifier.
