TDA2030 35 watt audio amplifier circuit

This TDA2030 35 watt audio amplifier circuit project is designed to provide an output power of 35 watts on to a 8 ohms load.
The TDA2030 is a monolithic IC in Pentawatt package intended for use as low frequency class AB amplifier.
The TDA2030 provides high output current and has very low harmonic and cross-over distortion.
This 35 watt power amplifier require a very good filtered DC power supply , that will provide an output voltage of +/- 16 volts .

Using this circuit you can design a very simple and efficiency subwoofer amplifier with a maximum output power of 35 watt power .
The device incorporates a short circuit protection system comprising an arrangement for automatically limiting the dissipated power so as to keep the working point of the output transistors within their safe operating area. Also a conventional thermal shut-down system is also included .

Can i be able to use 20v with 2 output speakers?

Can't I change the ic rather than using TDA What about when I use STK?

What STK ic you want to use? STK is not an equivalent for TDA and I think that most STK circuits needs additional protections for shortcircuit.
