Bi-wiring is a means of connecting a loudspeaker to an audio amplifier, primarily used in hi-fi systems. Normally, there is one pair of connectors on a loudspeaker and a single cable (two conductors) runs from the amplifier output to the terminals at the loudspeaker housing.
Bi-amping is the use of two channels of amplification to power each loudspeaker within an audio system. Tri-amping is the practice of connecting three channels of amplification to a loudspeaker unit: one to power the bass driver ( woofer ), one to power the mid-range and the third to power the treble driver ( tweeter ).
The article describes active loudspeaker systems. In audiophile circles though, bi- or tri-amping refers to the act of hooking up multiple amps to the individual binding posts of a passive speaker where each amp and speaker terminal receives the full signal and the passive crossover still does what it always does.
It is sometimes called a four-wire serial bus to contrast with three-wire variants which are half duplex, and with the two-wire I²C and 1-Wire serial buses. Typical applications include interfacing microcontrollers with peripheral chips for Secure Digital cards, liquid crystal displays , analog-to-digital and digital-to-analog converters ...

The ownership of on-premises wiring varies between jurisdictions: It depends on the location of the demarcation point. The location determines ownership and responsibility for maintenance and repair. [citation needed] In the United States and Canada, most premises wiring is owned by the customer.
In telecommunications, a four-wire circuit is a two-way circuit using two paths so arranged that the respective signals are transmitted in one direction only by one path and in the other direction by the other path. The four-wire circuit gets its name from the fact that is uses four conductors to create two complete electrical circuits, one for ...
