20w car audio amplifier circuit

20w car audio amplifier based TDA 2004

This 20w car audio amplifier circuit described here offers a 20 watt booster that will allow you to realize the power amplifier with which one can increase the power output from the car stereo up to 20 Watts maximum.

Audio amplifier with crossover

Two way 20 watts audio amplifier

This is a 20 watts audio amplifier is supplied with a voltage 14.4 volts, giving a total power of 20 watts into two different channels, each of which is connected to the tweeter and a woofer. […]

10 w mosfet amplifier

10 watts Mosfet Audio Amplifier

The scheme presented here is a MOSFET 10W audio amplifier circuit which requires only single power supply. Single rail supply is rarely used in Class-B power amplifiers. Anyway, it’s good enough for low power applications. In […]

36 watt power amp based TDA1562q

36 Watt Audio Power Amplifier based on TDA1562Q

The amplifier based on the class H from Philips audio amplifier IC, it can deliver 36W RMS and 70W power music, all from the supply voltage of 13.8V.  This amplifier can provide 36W RMS continuous into 4 ohm load when using a 13.8Vsupply.

30w stereo amplifier circuit

30W Stereo power amplifier based TDA 1521

It is small and compact stereo amplifier is powerful but can easily be used to replace your broken amplifier or new construction, or to make an active speaker, in all cases combined with a preamplifier. With remarkable features make it the true Hi-Fi amplifier.
