In general, the output voltage of an Audio Power Amplifier remains fairly constant as the load changes. The changes in output voltage as the load is varied occur for several reasons: resistance between where the negative-feedback point is in the amplifier to the output terminals, how much negative-feedback is actually used inside the amplifier, some other (minor) factors.

8V x 8V / 4R = 16 Watt. Therefore many vehicle sound systems use bridge amplifiers to power speakers. A popular belief is that 4 times the power is achieved from bridging 2 amplifiers in comparison to single ended application. This is partially true, but there is no such thing as something for nothing.

So there should be a volume control to allow for variation how large amplitude to output depending on how you are playing, and depending on what is the sensitivity of the input where the audio is fed. Line level output from modern DACs is 2 Vrms for full scale audio, which equals +/- 2.83 V or 5.66 Vpp.

That's an increase of (66.02/36)-1 = .83 or 83%. Because power increases with the square of the voltage a small increase in supply voltage will give a large increase in power output. So if our amplifier's output at 12 volts was 100 watts then at 14.4 volts it would be 144 watts and at 16.25 volts it would be 183 watts.

I did a quick experiment to compare the amplifier voltage output for the center channel between full range and 80 Hz crossover, using: The Dark Knight Rises, 04:35 to 06:35 Full range: Max 3.4 Vrms, Average 1.4 Vrms XO at 80 Hz: Max. 2.85V rms, Average 1.16 Vrms So the power difference is >40% between full range and XO=80 Hz in this particular test.

Now, modern head units offer dedicated RCA preamp outputs to make things easier. Manufacturers specify how much voltage their source units can produce on these preamp outputs. Most radios offer at least 2 volts of signal, but some offer 4 volt, 5 volt or even 8 volts. Does this preamp voltage matter?
