Simple Audio Amplifier with tda2003-10w

Using a very low number of external components you can build this simple amplifier using the cheap Tda2003 who has protection against DC and AC short circuit between all pins and ground, thermal over-range, load dump voltage surge up to 40V and fortuitous open ground.
The power supply can be between 8v and 18v making this amplifier a very usefull testing kit or general use in simple setups.
You can use Cx=0.039uF and Rx=39ohm , below is example of simple pcb
Vi is the signal input, +Vs is the positive power supply connector and the speaker will be connected between RL and ground
