power amp

This is the circuit that we will be using in our power amplifier..

**broken link removed**

Is it possible that the circuit above can be reduced to a single supply? If so,could you tell me what to edit?..

If that circuit is already ok,do i have to ground the other supply so that it would have a single supply?

Thank you very much!

I answered this question an hour ago on another website.

Of course a single polarity supply can be used if it has the correct voltage and if the input is biased at half the supply voltage and the speaker is coupled with a big capacitor.
Then the speaker will probably make a huge POP when it is turned on and another huge POP when it is turned off.
