Zusammenfassung:	Various aspects include audio amplifiers for driving at least one speaker. In some cases, the amplifier includes: a controller for amplifying at least one input signal to provide an amplified audio output signal, the controller configured to operate the amplifier in at least two modes, including: a first mode including a dedicated connection to the at least one speaker; and a second mode including a direct physical connection with an additional audio amplifier and the dedicated connection to the at least one speaker, where in the first mode and the second mode the amplifier is configured to provide the amplified audio output signal to drive the at least one speaker, and in the second mode the amplifier is configured to forward the at least one input signal to enable the additional audio amplifier to control audio output at an additional speaker.
