The power supply in either a guitar amplifier or in a professional sound amp reduces the 110v alternating current to a direct current. Also it reduces the voltage that can be used by the speakers, usually 12+ volts. Also if there where no power supply and there could be a possible way of reducing the voltage that could be used in the same was a direct current, you would here a constant phasing type noise from the current alternating. A power supply unit converts power that can be used in correctly in sound frequencies.
It doesn't. You can make a differential amplifier with a single power supply.
A voltage amplifier does not have to supply significant current bur a power amplifier does.
Power supply, oscillator, modulator, and amplifier.
you need to choose speakers according to the power supply of amplifier, so that the amplifier can wrok. Besides, to create good sound effect, you need to take your room area into consideration, if the room is small, amplifier and speakers with high power is not necessary. You can visit website of Unify company, they have many packages for amplifier and speakers, hope it can help somehow.
It is the power supply terminal.
Typically, the speaker cabinet is powered by the Amplifier. It's the amp that is raising the volume and power to make the speaker move. "Combo" amps have the amplifier and speakers in one box.
You need a 12volt dc power supply. Be aware that these get very expensive if you need more than 10 amps.

It depends on the specific models of each, but typically, Yes. Of course you will need a 12VDC power supply for the amplifier, though. You will also need a AV receiver with a preamp output. You cannot run speaker level outputs into the input of an amplifier.
Yes, an amplifier can be operated on ac supply.
It depends on where the wire is being used, but for the power supply for an ordinary domestic audio amplifier, wire of 0.75 mmsq is adequate, and need to be protected by a 5-amp fuse.
You need a power amplifier in between.
