When connected to an 8 ohm loudspeaker this would deliver: = ( ) ( ) = In most actual car systems, the amplifiers are connected in a bridge-tied load configuration, and speaker impedances are no higher than 4 Ω. High-power car amplifiers use a DC-to-DC converter to generate a higher supply voltage.
Sixteen ohm drivers (or loudspeakers systems) would be connected to the 16-ohm tap, 8 ohm to the 8 ohm tap, etc. This is significant since the ratio between the loudspeaker impedance and the amplifier's impedance at a particular frequency provides damping (i.e., energy absorption) for the back EMF generated by a driver.
Connecting a low-impedance load such as a loudspeaker (usually 4 to 8 Ω) to a line out will essentially short circuit the output circuit. Such loads are around 1/1000 the impedance a line out is designed to drive, so the line out is usually not designed to source the current that would be drawn by a 4 to 8 ohm load at normal line out signal ...
Recent models generally use Bluetooth 4.0 or even Bluetooth 5, and wireless speakers generally have a range of 10 meters. [4] Bluetooth devices use a radio communication frequency such that the devices do not have to be in a visual line of sight with each other. Some speakers may benefit from the NFC system to facilitate pairing with the source ...
A horn-loaded speaker can have a sensitivity as high as 110 dB at 2.83 volts (1 watt at 8 ohms) at 1 meter. This is a hundredfold increase in output compared to a speaker rated at 90 dB sensitivity and is invaluable in applications where high sound levels are required or amplifier power is limited.

The Home Speaker 500 is the flagship model in the Home Speaker Series, featuring larger drivers (speakers), and more room-filling sound. The 500 also features a color LCD display screen that is used strictly for song information (similar to the screens on early Apple iPod models).
