    No, but its easier and generally cheaper just to buy one ready made such as one of these.

    Can i ask you about the power amplifier cct, does it really have to use the class amplifier such class A, B etc, or can i just use an opamp instead?

    No. You need a power amplifier that can deliver many watts into a low impedance speaker load. An op amp can only provide a few tens of milliwatts of power into a high impedance load.
