Following is the TDA2030 DIY Powerful Amplifier. This circuit diagram with extent bass volume utilized in nearly all amplifier initiatives at this site. All the headings and photos are clickable to look at the associated mission motion pictures or downloading the circuit diagrams.
Take a be aware which you need to use aluminium heat sink with a fan (if possible) to save you over heating at the transistors. These circuits require symmetrical/twin and unmarried polarity strength deliver. The capacitors of strength deliver kind is electrolytic capacitor.

I would like to build a 2.1 channel subwoofer using Tda2030 but my problem am not able to source 680 ohm resistor but i have 510 ohm resistor ¼watt, can it be perfectly serve or i have to Get the exactly number?
510 will also work. but if you have two resisters of any number and their total is as required then you can join them in series will get the same resistant. Like 340+340, or 220+460 like wise.
Or if you have two double value resisters then join them in parallel, which will become half value of one resister’s value.
What is the recommended wattage of the speaker?
