Because the time of transistor amplifiers has passed, circuits very complicated for a beginner electronist, I'll focus on some simple things, easily achievable even by a beginner in electronics. In this article, I will introduce you a simple  2.1 audio amplifier made with the integrated TDA1554Q circuit.

Circuit to use the possibilities of the TDA1554Q which

 has 4 outputs, 2 simple for satellites and the other two bridged for the subwoofer.
The circuit has no balance.  Adjust  the overall volume  10 k pot   tone control  and volume 22K  pot  adjustment of the subwoofer.
We have a pre amp ic 4558 and bass filter

The circuit already has power supply by simply connecting a transformer (AC) simple 12-0-12  Volts / 3 Amps, can also be connected a source (DC) 12 volts / 3 amps
