What is the criteria for choosing capacitor and resistor values to obtain better sound quality? What i mean is, when i connect my speakers to the output of amplifier i designed they sound horrible. I tried randomly different capacitors and resistors couldn't find a solution.
Is there formula for that? I guess i should know the output impedance and speaker impedance? But then what should i do?
Edit to specify what is meant by "horrible"
There is hissing sound. There is noise. By horrible I meant there is some distortion which is not in the original recording.
