How to make a small amplifier?

How to make a small amplifier:

This is the circuit diagram for 20watts using tda2030. These chips run a 4Ω speaker at 18W or an 8Ω speaker at 14W. this circuit diagram runs with positive negative and ground voltage. we can use a maximum of 15-0-15 voltage. 12-0-12 voltage is the best for these chips. this is a mono-circuit diagram.
