To get all the audio voltage from a source to a target without loss you need voltage bridging, that is a relative low output impedance to a higher input impedance. Usualy the input impedance is at least ten times higher then the output impedance.
An input impedance is called also a load impedance or an external impedance.
An output impedance is called also a source impedance or an internal impedance.

Why do amplifiers have zero output impedance?
Good amplifiers have low output impedances. The reason is "impedance bridging". Scroll down to related links and look at "Calculation the damping of impedance bridging or power matching an interface connecting Zout and Zin".
What are the importance of impedance matching in amplifiers?
Two reasons. 1...When impedance of source and destination match, power transfer is maximum. 2...If a long transmission line is involved, the characteristic impedance of the line must match the destination impedance, or reflections will occur on the line.
In a multistage amplifier input impedance is high and output impedance is low justify the statement?
no. input impedance is low & output impedance is high
How do you connect 4 ohm speaker to 16 output amplifier?
No Problem to do this, but there are really no amplifiers with an output impedance of 16 ohms on the market. All loudspeaker amplifiers have an impedance of less than 0.5 ohm. Scroll down to related links and look at "Impedance bridging - Wikipedia".
Will a 4 ohm sub work on a 8 ohm system?
With system you mean the output impedance of an amplifier. No Problem to do this, but there are really no amplifiers with an output impedance of 8 ohms on the market. All loudspeaker amplifiers have an impedance of less than 0.5 ohm. Scroll down to related links and look at "Impedance bridging - Wikipedia".
Which is better high input impedance or low input impedance and why?
That depends on the output impedance. In electronic we use voltage bridging, that is a relative low output impedance to a higher input impedance. Usualy the input impedance is more than ten times higher then the output impedance. An input impedance is called also a load impedance or an external impedance. An output impedance is called also a source impedance or an internal impedance.
If an amplifier has an output of 350 watts rms 8 ohms what is the output at 4 ohms?
There is no amplifier with an output impedance of 8 ohms or 4 ohms on the market. All audio amplifiers really have an output impedance of less than 0.1 ohms. Scroll down to related links and look at "Amplifiers, loudspeakers and ohms"
Why is output impedance kept low?
To get all the audio voltage from a source to a target without loss you need voltage bridging, that is a relative low output impedance to a higher input impedance. Usualy the input impedance is at least ten times higher then the output impedance.An input impedance is called also a load impedance or an external impedance.An output impedance is called also a source impedance or an internal impedance.

Can 8 ohm subs be used on 4 ohm amps?
No Problem to do this, but there are really no amplifiers with an output impedance of 4 ohms on the market. All loudspeaker amplifiers have an impedance of less than 0.5 ohm. Scroll down to related links and look at "Impedance bridging - Wikipedia".
What kind of desk to use for 8 ohm amplifiers?
The output impedance of a power amplifier is always less than 0.1 ohms. There are no 8 ohm amplifiers on the market!
How do you parallel 2 speaker 8 ohm on 8 ohm amply?
No Problem to do this, but there are really no amplifiers with an output impedance of 8 ohms on the market. All loudspeaker amplifiers have an impedance of less than 0.5 ohm. Scroll down to related links and look at "Impedance bridging - Wikipedia".
