An audio system includes a variable voltage power supply and at least one remotely positioned speaker assembly. The speaker assembly includes a driver (e.g., a tweeter) and a switching amplifier. Moving the switching amplifier to a remote position within the speaker assembly provides numerous design advantages and allows for utilization of a smaller power supply. In addition, the audio system is configured to detect a type of the at least one speaker and to adjust an output voltage of the variable voltage power supply accordingly. This allows for reconfiguration and/or expansion of original systems. A related method of detecting a type of speaker electrically connected to an audio source is also provided.

An antenna apparatus is for use in connection with a light and a switch for selectively supplying power to the light through associated wiring. The apparatus comprises a circuit connected between the light and the switch, the circuit including a filter, a decoupling circuit, and an antenna formed at least in part by the wiring associated with the light. The apparatus may be used in connection with a light on a vehicle, such as a brake light for a motorcycle, and may thus be concealed from view. Related methods are also disclosed.
