Stereo Amplifier 44 Watt electronic kit
This electronic circuit is a gem; a TDA 1554 Integrated Circuit (included in this electronic kit) is used to produce an amplifier that will output up to 22 watts per channel with distortion typically not in excess of 0.1% thd. Sound quality is very, very high. Originally intended for use in an automobile, the kit could just as well be built for home use. If you build it to power-amplify your car radio, be sure that your speakers (4 ohms best, 8 ohms OK) are big enough to handle the power.
Special Note: An automobile generally provides from 13.6V to 14.4V when the engine is running. Anything between 12 volts and 14.4 volts DC will do but the amplifier can draw as much as five amps, so the average "wall adapter" is not going to work. If you do use an AC operated power supply; get a clean one with very low ripple.
